Gas Chromatograph BK-GC900

BK-GC900 gas chromatograph is a popular, high-performance, multi-functional series of chromatographic instruments. FID, TCD and FPD detectors can be combined as needed to meet the needs of ordinary laboratories, daily production, routine detection and trace quantities analysis requirements. It can be widely used in many fields such as petroleum, chemical industry, environment, food safety, disease control, teaching and scientific research.

Features

  • Ethernet communication interface is adopted, so that the instrument can realize long-distance data transmission through the internal LAN of the enterprise, which is convenient for the management of analysis data.
  • The unique design of the injection port solves the injection discrimination, and the dual-column compensation function not only solves the baseline drift caused by temperature programming, but also reduces the influence of background noise, which can lead to lower detection limits.
  • Unique vaporization chamber design, smaller dead volume; replacement of accessories such as injection pad, liner, polarizer, collector, nozzle can be done with one hand; packed column, capillary injector, TCD, FID detector and other main bodies The replacement only requires a wrench to be completely disassembled, and the maintenance is very convenient.
  • The intelligent rear door system has stepless variable inlet and outlet air volume, which shortens the stable balance time of the system after programmed heating/cooling.
  • The inlet can be installed up to 4 types (packed column, capillary column split/splitless injection system can be used), multiple detectors with the same or different detectors are installed, automatic/manual gas injection device can be selected, top Empty sampler, thermal desorption sampler, pyrolysis furnace sampler, methane reformer, etc.
  • The instrument is equipped with a 4.3-inch color LCD touch screen and keyboard input for user operation.
  • Adopt the dual-stable gas path design of primary pressure stabilizer valve and stabilizer valve/pressure stabilizer valve.
  • With seven temperature control devices, the temperature control accuracy is lower than ±0.1℃.
  • With double over-temperature protection and power-off protection function.
  • With linkage trigger signal acquisition system.

With fault self-check and alarm function.
