Reactions under high pressure and high temperature in a closed system
Polyamides that are hard to analyze by normal reactive pyrolysis GC or PyGC can be analyzed by organic alkali derivatization under high pressures and high temperatures.

Online GC analysis of reaction products.

After reaction in a sealed glass capsule, the products can be analyzed online directly by introducing them to a GC separation column without working up the reaction mixture.

High pressure reactions using a small amount of sample and reagent.

Only a few milligrams of sample and reagent are required for the On-line Micro Reaction Sampler; therefore, it is safe to handle.
