In any manufacturing industry, it is crucial to know exactly what chemicals you’re working with. Chemical testing labs that provide accurate, quantitative and qualitative chemical analysis enhance your control of the purity and composition of reagents and materials.
Engineers seeking to verify yield and purity for quality control and researchers investigating unknown chemical mixtures can rely on Covalent’s world-class team of analytical chemists and its full suite of spectroscopy instruments to solve problems faster. Covalent and its network of chemical analysis labs will help you identify and quantify elements, functional groups, and compounds with the exacting sensitivity needed for precise analysis of trace contaminants and impurities.
Attenuated-total-reflectance (ATR) is a sampling mode which enhances the Fourier Transformed Infrared Spectroscopy (FTIR) signal obtained from sample surfaces, increasing sensitivity and allowing efficient measurements with minimal sample preparation. Like standard FTIR measurements, ATR-FTIR is used for chemical qualification of a sample from raw optical spectra and is often used to determine organic composition.
Auger electron spectroscopy (AES) is a surface-sensitive analytical technique with high lateral resolution. It is used to quantify and map the elemental composition of the outermost 2-10 nm of a material.
Dynamic secondary ion mass spectroscopy (D-SIMS) is a technique used to analyze very low concentrations of elements in solid surfaces and thin films. The ability to detect up to ppb levels of trace impurities and dopants in solid materials makes D-SIMS the most sensitive surface analytical technique.
Gas Chromatography-Mass Spectroscopy combines two instrumental systems: a gas chromatograph component where the sample is volatized, followed by a mass spectrometer, which filters the incoming gaseous particles by their mass. This system outputs a quantitative representation of the chemicals present in a sample.
Glow discharge optical emission spectroscopy (GDOES) is a quantitative, chemical analytical technique used to study the elemental composition of solids. It is particularly well suited for analysis on thin- and thick-film samples, or for depth-profiling of multilayer film stacks.
Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) is a destructive chemical analysis technique which measures the elemental composition of a sample. It is one of the most sensitive multiple-element analysis methods, with detection limits down to ng/L.
Nanoscale secondary ion mass spectrometry is a highly sensitive chemical analysis technique used to acquire 2D and 3D maps of elemental distribution information with exceptionally high spatial and mass resolutions. It is typically used to produce images of elemental concentration. Covalent partners with Toray Research Center to offer NanoSIMS on one of only about 50 total instruments for this technique available around the world.
Nuclear magnetic resonance spectroscopy (NMR) is a chemical analytical technique used to assay the composition and chemical structure of solutions, solids, mixtures, and macromolecules. Due to its ability to capture dynamic molecular behavior, it can also be used to characterize reaction kinetics, real-time structural rearrangements, substrate binding and catalysis, and many other processes.
Raman spectroscopy is a chemical analysis technique which probes the vibrational modes of compounds. It produces a spectrum which can provide fingerprint identification of materials when compared against a reference library of known standards.
