Gas Chromatograph with EPC - Touch Screen GC System - 450°C Column Oven - 0.001 psi Control

The Master Science Gas Chromatograph EPC is a fully electronic GC with up to 18 channels of pressure and flow control and a 10-inch capacitive touch screen. Pressure is regulated to 0.001 psi with compensation for ambient temperature and pressure.

The column oven of 23 L or more runs from 2 °C above room temperature to 450 °C and heats at 250 °C per minute or faster. Three inlets and up to four detectors can be fitted, and dual independent ovens allow multi-valve, multi-column set-ups for gas analysis.
