Routine analysis of “dirty matrix” samples can contaminate a GC liner, leading to peak broadening and loss of analytes. This can happen within a few GC runs and is due to compound adsorption in the liner, therefore column backflush does not help. Under such conditions, frequent liner replacement is necessary, interrupting of the analysis while the liner is changed manually. Running a large series of samples under these conditions is a serious challenge. GERSTEL’s Automated Liner EXchange (ALEX) technology performs automated CIS liner exchange at user defined intervals when used with the GERSTEL MPS.
Automated Liner Exchange
Specially designed trays hold 40 CIS liners in individually sealed, contamination-free storage compartments. GERSTEL MAESTRO software provides integrated control of the MPS, ALEX system and CIS. In combination with the Agilent Technologies ChemStation or MassHunter software, a single method and sequence list control the entire system including GC and MSD.
