A new method has been developed to enhance the detection of the cannabinoids present in cannabis-based consumer products. This has been achieved by a team at the United States Food and Drug ...

In gas chromatography (GC) the paint sample is placed in a solution. This solution is then injected into a stream of gas, usually helium. This gas in turn is forced through a thin heated tube.
