The workhorse for all types of GC analysis. This model has “unit” resolution, a scan speed up to 500Hz, and a significantly larger pumping system than the Pegasus BT. It is therefore the versatile system for all types of GC analysis, from 0.53 (up to 10mL He / min) columns down to 0.10 and fast chromatography if desired.
Due to the high scanning speed and the robust pumping system, Pegasus HT-C is also particularly suitable for GCxGC analysis. Because of the cold-spot refocusing before the second dimension, in GCxGC the individual peaks are considerably sharper than conventional GC analysis. Typically, a peak elutes over a 35 – 200msec period, and good quantization typically requires 10 scans/top, which therefore requires to complete scans performed on <3,5msec, that is, around the 300scans/sec. This can only be achieved with a good TOF, but in this context it is essential that the software can manage the GCxGC data, that it is robust, logically constructed, and operates each time. This is what ChromaTOF does.
