Gas Chromatography LGC-B11

Overview

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.

Features :

  • 7-inch LCD display specifies temperature, gas flow and heating curve
  • H2 and N2 mobile gas phase with AFC and constant pressure gas flow type
  • Equipped with capillary analysis system and capillary split sampler
  • Injection system incorporates diaphragm cleaning, split flow and auxiliary gas adjustment
  • Standard unit for high-speed analysis with polar capillary column
  • PEG-20M and FFAP stationary phase polar capillary columns can be coupled
  • Dual FID detector with automatic flame ignition and baseline signal display
  • Self-diagnostic and automatic fault recognition function
  • Multi-core and 32-bit embedded hardware system ensures the reliable operation
  • Equipped with chromatography workstation software to process data
  • Memory function can store 20 sample test data
  • RS232 interface and LAN port
