Novel integrated digital electronic circuit has high controlling accuracy , stability and reliability . the temperature fluctuation can be controlled with in 0.001 ℃ . unique inlet solve the problem caused by deviation ; double-column compensation function can resolve the program drifting caused by raising the temperature and reduce the influence of background noise to get the least accuracy of detection . The volume of column box is large with intellective back-door system, and the air volume is stepless and variable.  So, the balance times of the system after programmed temperature raising or falling are shortened. Oven system: temperature range from ambient temperature＋7℃ to 400℃. Tree-stages programmed temperature with raising rates from 0 to 50 ℃/min,  temperature increment 0.1 ℃. User can re-adjust the oven temperatures, reset the highest temperatures at discretion, and set the balance times of the oven. Support fitting two inlet systems: packed column and split/splitless (S/SL) capillary(the septum can be self-cleaned); support fitting two same detectors or two different detectors: FID (flame ionization detector) , TCD (thermal conductivity detector) . Besides these , there are more selections, such as auto/manipulate six-channel gas ampler、headspace sampler、thermal resolution sampler、pyrolyzer sampler、methane reforming furnace. Detector system : FID (flame ionization detector) is convenient for take down and setting, it is also easy for cleaning  and changing nozzle; high resistance single column ECD with high accuracy, and shorten times for the baseline to stabilize (within 15 minutes). Inputting signal can be magnified logarithmically to reduce disturbance. The detector can use TCD, ECD, NPD, FPD and so on. The functions of the instrument consist of self-diagnose when starting up, stopwatch (for measure flow) , time controller, save data when power cut and keyboard lockout.   Technical target :           Temperature control Temperature control range : room temperature to 7~400℃ The order of programmed temperature : Tree-stages The rate of programmed temperature : 0.1℃~50℃/min (the increment is 0.1℃)           Detector FID Limit of detection : ≤5×10-12g/s (n-hexadecane) Baseline noise :    ≤6×10-12A/H Linearity range :   ≥105 Stabilization time : <20min           Detector TCD Sensitiyity : ≥10000mv·ml/mg (n-hexadecane) Baseline noise : ≤30uv (the purity of carrier gas is 99.999)           Detector NPD FPD Limit of detection : ≤5×10-12g/s (n-hexadecane) Baseline noise :    ≤2×10-13A/H   The configuration of GC5890 : serial  number instrument  name      configuration condition       remarks inlet  system detector system      1       GC 5890 packed column FID/TCD three-stages programmed temperature,back-door      2 capillary column + packed column TCD three-stages programmed temperature,back-door      3 capillary column + packed column FID/double-FID three-stages programmed temperature,back-door      4 capillary column + packed column FID/TCD three-stages programmed temperature,back-door      5 double- capillary column double-FID three-stages programmed temperature,back-door      6 double- capillary column TCD three-stages programmed temperature,back-door      7 capillary column + packed column FID+FPD three-stages programmed temperature,back-door      8 headspace sampler time frame setting : 0~99 min , temperature setting : room temperature to 110℃        9 RJ-1 pyrolyzer sampler temperature control range : room temperature to 900℃, temperature fluctuation : 1%       10 thermal resolution , reforming furnace heating-up range : room temperature to 400 ℃       11 auto gas ampler auto six-channel gas ampler , timing sampling analysis     南京科捷分析仪器应用研究所 Nanjing kejie institute of applied analysis instrument Phone : (025)83312752 83738955 84372482 Fax :  (025)83738955 84372482 Postalcode：210014 E-mail : kj17@21cn.com
