ORGANIC MASS SPECTROMETRY
Description
Gas chromatography/mass spectrometry (GC/MS) is an analytical method that combines the separative features of gas-chromatography with the identification capabilities of mass spectrometry to identify unknown organics in a sample. It is a natural complement to standard IVA®testing. GC/MS testing allows for comprehensive testing of a variety of different substances and sample matrices, from individual compounds to complex mixtures and polymers, offering a level of sensitivity, speed and analysis that cannot be beat. ORS offers organic mass spectrometry testing services and method development services to clients across a variety of industries and a wide range of products.
Oneida’s GC/MS analysis services can be performed via Static Headspace, solvent extraction and direct injection, direct air injection, residual solvent analysis, gas cylinder analysis, IVA® of hermetic devices, and outgassing of samples sealed in ampoules. Testing is qualitative, semi-quantitative, and can be customized to suit your analytical needs. Testing capabilities and a partial list of applications are presented below.
ORGANIC MASS SPECTROMETRY
Applications
Gas Chromatography/Mass Spectrometry (GC/MS): Common applications of ORS’ GC/MC analysis services include contamination identification, material outgassing studies, purity determination, and identification of “unknown” compounds in bulk organics.
Internal Vapor Analysis® Gas Chromatography/Mass Spectrometry (IVA®/GC/MS): Used for the analysis of organic constituents in the cavity of hermetic packages and ampoules, identifying of volatile and semi-volatile organics. Package volumes as low as 8 nL can be tested.
Static Headspace/Gas Chromatography/Mass Spectrometry: A useful technique for the analysis of volatile and semi-volatile organics off-gassing from low concentration components in bulk materials, including solid and liquid matrices.
Direct Air Injection/Residual Solvent Analysis/Gas Cylinder Analysis/Gas Chromatography/Mass Spectrometry: Used to analyze components of gas phase samples for volatile and semi-volatile organics. Incorporates Liquid N2 cryofocus for improved chromatography and sensitivity. Samples can be whole air/gas samples collected in gas sampling cylinders provided by ORS, pharmaceutical products in hermetic packages, or other suitable containers containing gaseous samples.
