Needs forDifficult GCSeparations:
•
Stationary phase selectivity shouldbe optimized
for particular separation, tomaximize resolution
andminimize run time
•
Column dimensions should bematched to
analytical requirements (flow, capacity, etc.)
•
Current offerings of stationaryphases and
functionalities are limited
•
Selectionof phase and column, andoptimization
of separations needs tobe easy for enduser
