Introduction of Gas Chromatographs for Mask Ethylene Oxide Residue Detection
       
  NB-4000A Gas Chromatographs               Head-space sampler
 
Main features
-Five detectors to choose (TCD, FID, FPD, NPD, ECD)
-Unit-type overall structure design, convenient for installation and maintenance
-Large-volume column box, three chromatographic columns can be installed at the same time.
-The design of the instrument is reasonable and flexible, and any three detectors can be installed at the same time, and there are three independent circuit systems and three signal output terminals.
-Flexible packed column and capillary column system can be connected with capillary columns of different calibers.
-Stable temperature control system, 10-stage temperature program, sampler and each detector can be independently controlled temperature, and has over-temperature protection function.
The heating zone can be controlled by seven channels
-The host automatically ignites analysis through the workstation
-Strong expansibility, the instrument can be upgraded to GC/MS
Inlet: Magnetic fixed sampling system is adopted.
