Element

Gas Chromatography Mass Spectrometry, or GC/MS analysis, is a method used to determine trace and single elements in complex chemical mixtures. Rather than giving a full elemental breakdown, gas chromatography focuses on one element or compound in a substance.

GC/MS is a beneficial method for materials where a very small amount of the compound under test is suspected, or when 100% certainty of an element is required. Because of its singular elemental focus, gas chromatography is generally considered one of the most accurate analyses available. 

Element has world-class gas chromatography equipment, capable of performing both liquid injection and thermal desorption methods. Our experts are highly trained in GC/MS testing and supporting chemical methods, making Element the partner of choice for complex projects requiring a high level of accuracy. In addition to being ISO 17025 accredited, our GC/MS program is approved by the US. Consumer Product Safety Commission (CPSC), allowing us to stay up-to-date on compliance and regulatory requirements.

GC/MS Techniques

Gas chromatography mass spectrometry is usually performed in one of two ways: either through thermal desorption or liquid injection. Thermal desorption starts with a solid sample. The sample is then vaporized, and the resulting gas is analyzed for presence of the target substance. With liquid injection, a small sample of aqueous substance is injected into the GC/MS equipment, and the results are analyzed. In both cases, the sample must be discarded after testing. If more than one substance is under investigation, multiple samples must be provided.
