There are many different methods of chromatography, but in the cannabis industry, the two most widely used methods are gas chromatography GC and liquid chromatography LC , and more particularly, high performance liquid chromatography HPLC.
Non-gas chromatography methods like HPLC are generally preferred because GC adds high amounts of heat to samples, decarboxylating cannabinoids in the process. Essentially, it measures the masses of molecules and chemical compounds within a sample.
By ionizing compounds and subjecting them to an electric or magnetic field, their deflection rate can be displayed in a spectrum that can be analyzed. They are sorted by their mass-to-charge ratio. GC and HPLC testing require large amounts of solvents and can be incredibly time-consuming, so those methods drive up the price of testing.
