FTIR Spectrometry

Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time. Fourier transform infrared spectroscopy is used in geology, chemistry, materials and biology for and research fields.

Ultraviolet & Visible Spectrometry

Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, atoms and molecules undergo electronic transitions. UV/Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of different analyses, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied.

Mass Spectrometry

Mass spectrometry (MS) is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. In simpler terms, a mass spectrum measures the masses within a sample. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical structures of molecules, such as peptides and other chemical compounds. Mass spectrometry has both qualitative and quantitative uses. These include identifying unknown compounds, determining the isotopic composition of elements in a molecule, and determining the structure of a compound by observing its fragmentation. Other uses include quantifying the amount of a compound in a sample or studying the fundamentals of gas phase ion chemistry (the chemistry of ions and neutrals in a vacuum). MS is now in very common use in analytical laboratories that study physical, chemical, or biological properties of a great variety of compounds.

Gas Chromatography

Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analysing compounds that can be vaporised without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

Carbon/Nitrogen/Sulfur/Chlorine Analysis

Elemental analysis is a process where a sample of some material (e.g., petrochemical, soil, waste or drinking water, minerals) is analysed for its elemental composition. This information is very important for organic chemists working in refineries and quality control labs to ensure a high quality finished product, optimize production processes and ensure that the product complies with the laws and market regulations. Our products are compliant to standards such as EN ISO 20846, safe, cost-effective and fully automated.

TOC Analysis

Total organic carbon (TOC) is the amount of carbon found in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.

ICP-OES

Inductively coupled plasma optical emission spectrometry (ICP-OES), is an analytical technique used for the detection of chemical elements. It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. It is a flame technique with a flame temperature in a range from 6000 to 10000 K. The intensity of this emission is indicative of the concentration of the element within the sample.

X-Ray Fluorescence Spectrometry

X-ray fluorescence (XRF) is the emission of characteristic “secondary” (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects such as paintings and murals.

Atomic Absorption Spectrometry

Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. In analytical chemistry the technique is used for determining the concentration of a particular element (the analyse) in a sample to be analysed. AAS can be used to determine over 70 different elements in solution, or directly in solid samples via electrothermal vaporisation, and is used in pharmacology, biophysics and toxicology research.

pH Meters

The pH value of foods has a direct effect on the growth of microorganisms and therefore on food quality and safety. For this reason, many companies use the pH value as a quality characteristic for evaluating their food. For example, the pH value is of great importance in the manufacture of meat, sausage, delicatessen and dairy products. The pH value is an important quality parameter in the food sector. It particularly affects the properties of meat and meat-based products, especially with regard to water binding capacity, taste, colour, tenderness and shelf life. In the bakery sector, the acidity of the sourdough can be determined by means of the pH value. In the case of products such as salad dressings, the pH value helps to ensure consistent quality or consistent acidity of the product.

Colorimeters

A colorimeter is a device used in colorimetry. In scientific fields the word generally refers to the device that measures the absorbance of particular wavelengths of light by a specific solution. This device is commonly used to determine the concentration of a known solute in a given solution by the application of the Beer-Lambert law, which states that the concentration of a solute is proportional to the absorbance.

Dataloggers

The data monitoring system testo Saveris measures temperature and humidity values in sensitive goods and products, in the surroundings and in processes. The easily operated measurement system provides security as well as savings of time and costs thanks to automated measurement data recording. The measurement data transfer takes place by wireless and/or Ethernet connection-to a Base station. This documents and monitors all measurement data. If limit values are exceeded, a number of alarm options such as SMS/e-mail alarm or alarm relay are available. Remote alarms can also be triggered even when the system is not connected to a running PC. In addition to this, transmitters of all measurement parameters with standard current/voltage interfaces can be integrated into the testo Saveris system. The integration not only of Testo transmitters, but also those of other manufacturers is possible. All recorded data are centrally stored in a software. At the same time, the testo Saveris software also allows a comprehensive analysis and evaluation of all recorded measurement data.

Anemometers

Every duct inlet and outlet should only contain the volumetric flow that, according to its calculations, is the basic requirement for a system that works efficiently. It must therefore be possible to measure the volumetric flow in a reliable way.

Luxmeters

Pressure Gauges & Transmitters

Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure gauges or vacuum gauges. A manometer is a good example as it uses a column of liquid to both measure and indicate pressure. Likewise the widely used Bourdon gauge is a mechanical device which both measures and indicates, and is probably the best known type of gauge.

Temperature Gauges & Transmitters

Temperature measurement, also known as thermometry, describes the process of measuring a current local temperature for immediate or later evaluation. Important devices for measuring temperature include: Thermocouples, Thermistors, Resistance temperature detector (RTD).

Differential Pressure Gauge

The measurement of gas flow and static gas pressure in the system are especially important. Because the burner can only operate well at a flow pressure between approximately 18 to 25 mbar. Outside this range, explosive flame formation can occur. The consequences are malfunctions or even breakdown of the heating system. For this reason, the acquisition of a reliable, easy-to-operate differential pressure measuring instrument is worthwhile.

Level Gauges & Transmitters

Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a peak. The substance to be measured can be inside a container or can be in its natural form (e.g., a river or a lake). The level measurement can be either continuous or point values. Continuous level sensors measure level within a specified range and determine the exact amount of substance in a certain place, while point-level sensors only indicate whether the substance is above or below the sensing point. Generally the latter detect levels that are excessively high or low.

Alarm Gas Detectors

The ALTAIR Gas Detectors are capable of measuring from 1 to 6 gases simultaneously and is now available with integrated PID sensor for VOC detection. Driven by advanced MSA XCell® Sensor Technology, the ALTAIR Gas Detector delivers faster response time, better stability, accuracy, longer service life, and cost savings over the life of the instrument.

Chemical Fume Hoods

Is a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts.

Water Stills

A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale. Stills have been used to produce water for Injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol.

Pure Water Systems

Pure water, also known as purified water, is water from a source that has removed all impurities. Distilled water is the most common form of pure water. … Pure water can be used in cooking, drinking, scientific studies and laboratories.

Centrifuges

A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a potentially strong force perpendicular to the axis of spin (outward). Centrifugation is a process and is used in industrial and laboratory settings. This process is used to separate two miscible substances, but also to analyze the hydrodynamic properties of macromolecules. More-dense components of the mixture migrate away from the axis of the centrifuge, while less-dense components of the mixture migrate towards the axis. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top.

Ultrasonic Baths

Ultrasonic cleaning is a process that uses ultrasound (usually from 20–400 kHz) and an appropriate cleaning solvent (sometimes ordinary tap water) to clean items. The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned and the type of soiling present enhances the effect.
