Gas Chromatography LGC-B11

Description :

Gas Chromatography LGC-B11 is a benchtop unit with advanced flow controller (AFC) technology. System has digital control mode and polar capillary columns to separate polar analytes. GC oven is capable of 9 temperature program ramps and hold steps, and features rapid cooling: 250 °C to 50 °C < 10 minutes. Accurate flow rate control via AFC has higher level repeatability of retention time and peak area, enabling specific level of analysis by means of dual FID detectors.
