Gas chromatography (GC) is an analytical technique used to separate and analyze volatile and semi-volatile compounds in a mixture. GC is used to help identify components of a liquid mixture and determine their relative concentration. It can also be used to separate and purify components of mixture. It is applied in many industries, including environmental, agriculture, petroleum, chemical, food and beverage, cosmetics, and pharmaceutical. We use chromatography for drug purity, food purity, pesticides, and various other samples. It uses a carrier gas known as the mobile phase, and the stationary phase is a microscopic layer of liquid or polymer on an inert support, inside a column. The range of GC detectors available, combined with our expertise, ensure quality service. We encounter lots of unique samples that may have unconventional testing requirements or specifications. If you are unsure what type of test or instrument is required to analyze your sample, give us a call and we’ll make sure it’s tested the way you want it.
We use them for
- Identifying chemicals
- Detecting the presence of contamination
- Determination of the quantities of chemicals in a product (assay)
- Quality Control
- Ensuring the product meets specifications
