Gas Chromatography
Gas Chromatography (“GC”) is an analytical technique used for separating liquids or gases via a capillary column, using gas as the solvent medium.
This technique is used to characterize, identify, and quantitate volatile and semi-volatile components in various sample matrices. Contaminants can be determined from the percent level to part per billion (“PPB”) depending on the analyte being detected.
While GC is performed in a temperature controlled oven, it is the detector to which it is coupled that determines what can be seen. At Element Midland, our scientists can use detectors such as:
- Flame Ionization Detection (FID)
- Thermal Conductivity Detection (TCD)
- Electron Capture Ionization (ECI)
- Mass Spectrometer (MS)
- Odor Analysis
By utilizing both purchased (NIST) and in-house spectral databases, our scientists can identify unknown or dangerous chemicals like Diethylene Glycol (“DEG”) and Ethylene Glycol (“EG”).
EG is a toxic chemical that is found in antifreeze and industrial applications; if ingested, it can cause serious health issues. DEG is a similar chemical that is even more toxic; it has mistakenly led to poisoning deaths due to its presence in cough syrups and other liquid medicines. Due to this, gas chromatography has proved to be a vital pharmaceutical contamination testing technique.
Element Midland is committed to cracking down on these contaminants that have been linked to global health risks by offering both EG testing and DEG testing. Gas chromatography testing for DEG and EG ensures these toxins stay away from public consumption and consumer products.
The gas chromatographers at Element Midland are qualified for testing under cGMP or GLP (FDA, EPA) guidelines.
