Gerstel’s PFC allows the use of GC as a purification method for difficult separable components and may over a few days collect sufficient material for a subsequent or 14C or NMR analysis. The same sample is run again-and-again and the selected components are sent to the cold traps. The system may be absolutely essential for the characterization of newly found components in biological matrices.
PFC is equipped with six traps and a “waste”. Cold traps are available with a trapping volume of 1μL or 100μL, cooling may be chosen between LN2 or cryostatic (-30 ° C) cooling. The system allows for the collection of individual compounds, a number of compounds, or certain classes of compounds. With microprocessor control the cold traps may be selected deselected in 0.01 minute increments. This allows the reliable collection of closely eluting components.
PFC is designed without valves or cold spots in the flow paths, ensuring maximum transfer efficiency.
The reliability and reproducibility of the system makes it possible to collect components over several hundred injections.
