Future Prospects

Much of the early work on the separation of free amines was done with columns packed with PEG and KOH on diatomaceous earths. Although this approach was reasonably successful, the analysis of free amines on packed columns has now largely been replaced by analysis on fused silica capillary columns. Application of capillary columns is expected to increase as further developments in these columns, e.g. shorter inactive columns with smaller internal diameters giving ultra-high column efficiency and speed, higher temperature phases and exterior coating for the fused silica tubing, permit the analysis of both high temperature and highly volatile amines. Furthermore, simple, rapid and automatic analysis of free amines in various samples will be achieved by combination with convenient sample preparation techniques such as SPME.
