Characteristics of GC-2010 gas chromatograph
1Adopting320 x 240dot matrix5.7An inch large screen LCD Chinese display, real-time display of various temperatures and operating conditions, clear and intuitive content, truly realizing human-machine dialogue; 2Power on self-test, wide range self diagnostic function, can accurately determine the fault location and alarm; 3Six independent temperature controls (vaporization chamber and capillary vaporization chamber can be independently controlled),Five level program heating function; 4OvertemperatureProtection function: If any circuit exceeds the set temperature, the instrument will automatically power off and sound an alarm; 5The vertical heating device of * makes sample vaporization more reliable, reduces the heat radiation generated in the vaporization chamber to the minimum, and ensures minimal temperature deviation inside the column box; 6Intelligent fuzzy control rear door opening system, automatically tracks temperature and dynamically adjustsThe angle of the air door can achieve precise temperature control even near room temperature; 7Configure filling column head injection, glass lining injection, with diaphragm cleaningFunctional capillary diversion/Non split injection device and capable of installing gas injectors; 8High precision dual stable gas path, capable of installing four types of detectors simultaneously; 9Optional electronic flow pressure display system with built-in workstation device. Temperature control indicators 1.Temperature control range: room temperature 5℃~400℃increment0.1℃ 2.Temperature control accuracy: superior to±0.01℃ Program heating: Five step interval constant temperature time0~999minincrement0.1minTemperature increment0.1℃ Heating rate:200℃The biggest one below40℃/min 200℃Up to the biggest20℃/min
Note: Dimensions: 660 * 460465mm machine weight: 60kg input power supply: AC 220V ± 10% 50HZ 2KW
