Features
|
|
characteristics of fast GC:
decreased column diameters, high heating rates and decreased column
lengths for faster GC separations with high resolution efficiency;
small inner diameters combined with very fast temperature programmes
can reduce the analysis time by up to 80 %
|
|
high heating rates place special demands on stationary phases: OPTIMA®
columns meet exactly this requirement, as they show very low bleeding
and provide long lifetimes, even when continuously subjected to high
heating rates

|
system requirements for fast GC:
small inner diameters result in high column inlet pressures and a lower
volume flow of the mobile phase, which as a consequence require very
fast injection of very small samples against a high pressure
the amount of sample, which can be injected, is limited by the inner diameter and the thin film
high sensitivity detectors with small volume and extremely short
response time, as well as a very rapid data acquisition and processing
are required
