Finnigan A200S Autosampler

Automation of laborious, tedious, repetitive tasks in an analytical laboratory has received a great deal of attention in the last decade. One area that still has to catch up is the automation of sample preparation. Even though the analysis of a sample is a standardized procedure, sample preparation has been left with many uncertainties and variations. Analytical methods normally start as hand-methods. Automatic analyzers have been developed, but sample preparation and the loading of samples are still plagued with many uncontrolled variables, which hamper higher reproducibility and productivity. CTC Analytics is making a substantial contribution in the sample preparation and injection areas. The GC autosampler CTC/Leap/Finnigan A200S for many commercial testing, pharmaceutical research and chemical industry laboratories has become the autosampler of choice. The A200S provides a great deal of flexibility. The autosampler fits onto practically all GC brands and models that have vertical injection ports. That hardware adaptability is combined with user selectable parameters, which provide full optimization of the injection method for each application. The basic parameters are sample volume, number of needle washes with two different solvents, syringe plunger speeds, and pre- and post injection delays.
