Thermal analyzer

Thermal analyzerIt is a fully automatic dual channel thermal desorption instrument with direct injection. The gas path adopts a combination of electric six way valve and solenoid valve, which can automatically program the desorption, injection, and blowback processes of the adsorption tube. The heating temperature of the adsorption tube and the pipeline can be independently set, and synchronous signals are output during injection. Chromatography and workstation can be started simultaneously.

Thermal analyzerDetailed introduction of instrument performance:
1) Thermal analyzer connected to chromatographic working conditions
Power supply: 220 ± 22VAC, 50 ± 0.5Hz (ensure reliable grounding of power supply ground wire and chassis grounding)
Environmental temperature:+5 ℃~35 ℃
Relative humidity: ≤ 85%
2) Thermal analyzer connected to chromatographic technical indicators
a. Power:<300VA
b. Gas path pressure resistance:>0.4MPa
c. Synchronous signal output: Two 1-2 second switching signals

Thermal analyzerConnection chromatography for daily use:
1. Turn on the power switch, check if the time and temperature settings are appropriate, and then wait for the instrument to heat up to the preset value.
2. Connect the adsorption tube and place it on the bracket in front of the heating box. After the temperature reaches the set value, start the desorption process according to the user's own needs, as shown in the following figure. The reference time for each stage is: desorption for 5-10 minutes, injection for 30 seconds, and blowback for 10-20 minutes. The desorption process of the standard sample is only to inject the standard sample from the three-way injection port on the right during the "blowing" stage, and the rest is the same.
3. After desorption is complete, place the adsorption tube on the front bracket of the heating box to cool down before removing it, and then install the next sample adsorption tube.
4. Due to the temperature control system of this desorption instrument, it can independently activate the sample adsorption tube.
