Gas Chromatograph • The Gas Chromatograph must use a 30-meter fused silica capillary column as stated by the EPA 524.2 Method. • Must have an integrated keypad (or touchscreen) for manual entry of parameters and built-in screen readout of settings and instrument status. • The system must have capabilities for independent temperature set- points for inlets, column oven, transfer lines and interfaced detectors. • Must be capable of rapid cool down cycle (minimum acceptable would be on the order of 450ºC to 50ºC within <10 minutes.) • GC must have a minimum of two inlets that could work independently with multiple detectors (if needed). • GC System is to be equipped with all method approved columns for the following methods: VOC (Full panel) using EPA 524.2 THM using EPA 524.2 • GC must be equipped with electronic pneumatics to automate and maintain pressures for both inlets and column. All pneumatics must be controlled electronically by the instrument software without the use of manually adjusted knobs or valves. The flow of gas through the system must be accurately measured by internal meters that are displayed in the instrument software interface. The software must have sensors to detect pressure drops (to detect leaks).
