5 Detectors to choose
Thermal Conductivity Detector (TCD) : Used for macro analysis of gases and liquids.
Flame Ionization Detector (FID): Used for analysis of hydrocarbon group and of organic in other fields.
Flame Photometric Detector (FPD): Used for trace level analysis of sulfide and phosphide.
Nitrogen-Phosphorus Detector (NPD): Used for trace level analysis of nitride and phosphide.
Electron Capture Detector (ECD) : Measure compounds that are capable of capturing the electrons.
A5000 Chromatography Data Workstation:
TD-01 Thermal Desorption Device
Coupled with GC, TD-01 Thermal Desorption can be used to detect total volatile organic compound (TVOC) for indoor or outdoor air samples.
Features
n Heating system controlled by a microprocessor. Uniquely designed heating oven. Quickly rise/drop 
temperature. Safe operation and good repeatability.
n Simple touch buttons on the panel, making operation easy to understand. From beginning of desorption program, to raise to temperature and inject the samples, the whole process can be completed automatically.
Unique “trigger” structured design for sampling tube, making assembling and disassembling the sampling tubes quick and convenient, suitable for analyzing large quantities of samples.
