Type of Detectors

Detectors are the flame ionization detector (FID) and the thermal conductivity detector (TCD). Both are sensitive to a wide range of components, and both work over a wide range of concentrations. While TCDs are essentially universal and can be used to detect any component other than the carrier gas (as long as their thermal conductivities are different from that of the carrier gas, at detector temperature), FIDs are sensitive primarily to hydrocarbons, and are more sensitive to them than TCD. However, an FID cannot detect water. Both detectors are also quite robust. Since TCD is non-destructive, it can be operated in-series before an FID (destructive), thus providing complementary detection of the same analytes.

Also various other detectors are also available: CCD, ECD, TID, PID, PDD etc.

Atomic Absorption Spectrophotometer

Atomic absorption spectroscopy (AAS) is a common technique used in many analytical chemistry protocols, as well as applications requiring a high degree of precision and accuracy, such as food & drug safety, clinical diagnostics, and environmental sampling. Atomic absorption spectrometers may be used to analyze the concentration of over 70 different elements in a given sample solution, making them a very valuable instrument in any laboratory procedure that requires reliable measurements and reproducibility.

Atomic absorption spectroscopy relies on the Beer-Lambert law to determine the concentration of a particular analyte in a sample. The absorption spectrum and molar absorbance of the desired sample element are known, and each element will preferentially absorb light at a particular wavelength, due to each element having a defined and discrete quantity of energy required to promote its electrons into higher orbitals (excited state). During atomic absorption testing, a known amount of energy is passed through the atomized sample, and by then measuring the quantity of light remaining after absorption it is possible to determine the concentration of the element being measured. The technique behind atomic absorption spectroscopy instruments has a great impact in many different applications, ranging from one of the first instruments that a science student will work with, to an instrument that leading scientists around the world use every day.

Background correction techniques, such the built-in self-reversal (Smith-Hieftje) correction method and deuterium background correction adjust for molecular absorption overlap which would otherwise result in false atomic absorption spectroscopy rates.

Various industry sectors and applications that rely heavily on atomic absorption spectroscopy are drug research and design, metallurgy and mining industries, petroleum industries, health and medical services, forensic science, clinical diagnostics, food safety, agriculture, and environmental monitoring. With an ever-increasing number of uses for atomic absorption spectrometry,

We hope to help the progress and the development of all of these fields by providing a quality line of atomic absorption spectrometers that will ensure reliable analyte measurements as well as reproducibility.

Elemental Analyzer

Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition. Elemental analysis can be qualitative (determining what elements are present), and it can be quantitative (determining how much of each are present). Elemental analysis falls within the ambit of analytical chemistry, the set of instruments involved in deciphering the chemical nature of our world.
For organic chemists, elemental analysis or "EA" almost always refers to CHNX analysis—the determination of the mass fractions of carbon, hydrogen, nitrogen, and heteroatoms (X) (halogens, sulfur) of a sample. 

We offer various models to determine the structure of an unknown compound, as well as to help ascertain the structure and purity of a synthesized compound according to our customer needs. 

TOC Analyzers

A typical analysis for TOC measures both the total carbon present as well as the so called "inorganic carbon" (IC), the latter representing the content of dissolved carbon dioxide and carbonic acid salts. Subtracting the inorganic carbon from the total carbon yields TOC. Another common variant of TOC analysis involves removing the IC portion first and then measuring the leftover carbon. This method involves purging an acidified sample with carbon-free air or nitrogen prior to measurement, and so is more accurately called non-purgeable organic carbon (NPOC).

Our range of TOC Series utilizes the 680 °C combustion catalytic oxidation method to efficiently analyze all organic compounds. With a wide sample range from 4 μg/L to 30,000 mg/L, the TOC is suitable for analyzing ultra-pure to highly contaminated samples of wastewater, brine water, seawater, drinking water and pharmaceutical water. 

The TOC Series offers a number of features, including automatic sample acidification and sparging, an automatic dilution function, and a zero-maintenance Peltier cooler, for easier, more accurate analysis. A number of options, including salt kits, autosamplers, and a total nitrogen module, improve productivity.

Thermogrvimetric Analyzer

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a type of testing performed on samples that determines changes in weight in relation to change in temperature. Such analysis relies on a high degree of precision in three measurements: weight, temperature, and temperature change. As many weight loss curves look similar, the weight loss curve may require transformation before results may be interpreted. A derivative weight loss curve can identify the point where weight loss is most apparent. Again, interpretation is limited without further modifications and deconvolution of the overlapping peaks may be required. To determine composition and purity one must take the mass of the substance in the mixture by using thermal gravimetric analysis. Thermal gravimetric analysis is the act of heating a mixture to a high enough temperature so that one of the components decomposes into a gas, which dissociates into the air. It is a process that utilizes heat and stoichiometry ratios to determine the percent by mass ration of a solute. If the compounds in the mixture that remain are known, then the percentage by mass can be determined by taking the weight of what is left in the mixture and dividing it by the initial mass. Knowing the mass of the original mixture and the total mass of impurities liberating upon heating, the stoichiometric ratio can be used to calculate the percent mass of the substance in a sample. TGA is commonly employed in research and testing to determine characteristics of materials such as polymers, to determine degradation temperatures, absorbed moisture content of materials, the level of inorganic and organic components in materials, decomposition points of explosives, and solvent residues. It is also often used to estimate the corrosion kinetics in high temperature oxidation.
Simultaneous TGA-DTA/DSC measures both heat flow and weight changes (TGA) in a material as a function of temperature or time in a controlled atmosphere. Simultaneous measurement of these two material properties not only improves productivity but also simplifies interpretation of the results.
