A dedicated GC– MS analyser was developed to address the increasing need for more sensitive catalyst poisoner analysis. The system combines the separation power and robustness of a classic backflush configuration with the selectivity and sensisitivitiy of mass spectrometry.
Can databases of column characteristics be used to help with HPLC column selection ahead of method development?
A GC–MS analyser is described that is reported to substantially expand the workable application range of a classic catalyst contaminants analyser. The use of FS/SIM mode permits identification of unknown contaminants in combination with reliable quantification at trace and ultratrace amounts.
