Parallel Processing for Sample Cleanup The GPC Quattro from Pickering Laboratories can be used to run four GPC columns with the same method or four fully independent methods, providing a fourfold increase in productivity in comparison to traditional single-column instruments. The instrument is suited for cleaning up complex animal tissues, food products and environmental samples by separating high molecular weight matrixes, such as lipids, carbohydrates, and pigments, from analytical samples. Concentrated samples can be easily analyzed by GC, GC-MS, HPLC and LC-MS. The GPC system includes full error management, so it can be safely operated without an operator in attendance. Storage run timers make resuming the sample or aborting the run easy in the case of a power outage. Safety features include high- and low-pressure shut-off, and waste level sensor with shut-off and defined “load” and “inject” positions. The instrument delivers a maximum operating pressure of 1000 psi (70 bar), making it suitable for low and medium pressure GPC columns.
