A substantial proportion of all domestic aviation accidents and fatalities that occur each year involve GA, which includes all aviation except commercial and military.

Another difference is the type of matter that the techniques can separate. In thin layer chromatography, the compounds are usually solids and some liquids. Meanwhile, gas-liquid chromatography separates gases.
