High Temperature Furnace
Room temperature ranges to 1100°（temporary use above 1100°）
Heating ratio 1-50℃ /min，not only the fast heating control but also the slow heating
Shell type which can dissipate heat open, cool to the room temperature within in 20 min with fan
Gas Circuit Port
Three paths of carrier gas (He, Ar, etc)
Three paths of reaction gas (H2, CO, CO2, O2, NH3, etc)
Three paths (analysis gas exit, carrier gas exit and reaction gas exit)
Flow Control
Two MFC control the flow, the range is: 0-100ml/min
Setting MFC parameter of different gas via the software, also for mixture
TCD
TCD, specially treated detector with safety device and secondary enlarging system
Detector close to the reactor, has very small dead volume
Vapor Generator
Equipped with thermocouple and soft heating jacket, it can vaporize the liquid carbinol, Ethanol and pyridine, etc.
Dewar Flask and Cold Trap Tube
Low temperature liquid can be kept in the Dewar flask (like liquid nitrogen or mixture of liquid nitrogen and isopropanol
Cold trap tube can cool the liquid products of TPR and TPSR
Reactor
U quartz tube, OD 8mm，ID 6mm, maximum 1300°
Internal thermocouple for temperature, measurement point is on the catalyst surface
Pipeline
3mm stainless iron pipeline, 316 stainless iron material, and smooth treatment for the inner wall of the pipe
Solenoid Valve
Solenoid valve controls the pipeline switch and selections, service life over 1 million
Selecting different valve body, spool and sealed material according to different air,
Sealing
Selecting fluororubber Perfluor rubber and graphite according to different application environment
Thermal Conductivity Cell Thermostatic
Thermal conductivity cell temperature controlled, precision is 0.2%FS
Lower cell temperature can be used on the condition of inorganicgas, therefore improve the TCD precision
