Leco Pegasus HRT
Pegasus GC-HRT – the high resolution MS:
This is the instrument for demanding non-target GC analyses, where the combination of good EI (and/or CI) spectra together with exact mass spectra is essential for the identification of unknowns in the chromatogram. However, this does not help if you also handle isomers in the analysis. Here GCxGC is yet another essential tool, see below:
GCxGC
Due to the high scanning speed and the robust pump system Pegasus GC-HRT 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. The system has, due to the long flight path, “only” a scan speed of up to 200 spectra / sec, and it is therefore necessary with a small compromise in terms of the number of scans per peak.
The sharpest peaks, down to 35msec, can only be expected to reach 5-6 scans over the peak, and peaks in 35 – 50msec interval can therefore be expected to be less accurate quantitated.
However, the combination of comprehensive GC and a high-resolution MS is a unique combination in the identification of unknowns. Again, 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.
