Fully automatic chemical adsorption instrument HL1800

Beijing Haixinrui Technology HL1800 SeriesFully automatic chemical adsorption instrumentFor automated instruments, various chemical adsorption and programmed temperature reactions can be studied, and information on the physical properties of catalysts, catalyst supports, and other materials can be obtained. Researchers can study active metalsSurface area, surface acidity, distribution and strength of active sites, specific surface area, and other properties. The HL1800-MP series chemical adsorption instrument can perform pulse chemical adsorption, temperature programmed reduction (TPR), temperature programmed desorption (TPD), temperature programmed oxidation (TPO), and temperature programmed reaction, and multiple analyses can be designed in the same experiment.

1 HL1800Fully automatic chemical adsorption instrumentMain technical parameters:

1.4 internal temperature control zones can be independently heated, with pipelines reaching up to 150 ℃. Avoid condensation points in the pipeline (the pipeline temperature can be increased to 300 ℃ according to actual needs).

2. Steam experiments can be conducted.

3. The small volume of the internal pipeline ensures high resolution and fast detection, reducing the deviation in calculating gas volume.

4. A high-sensitivity linear heat conduction detector (TCD) ensures that the calibration volume remains constant, so that the peak area is proportional to the volume of the reaction gas.

5. Four high-precision mass flow meters ensure highly accurate and programmable gas flow control, ensuring baseline stability and precise measurement of gas volume.

6. The corrosion-resistant detector filament can analyze most corrosive gases and reduce filament oxidation.

7. The open close heating furnace can heat quartz sample tubes to 1200 ℃ (which can be increased to 1800 ℃ according to actual needs). Multiple heating rates and analysis parameters can be set for easy design and analysis experiments. Cooling furnace can quickly lower the furnace temperature to ambient temperature, shorten analysis time, and increase testing volume.

8. Twelve inlet ports for preparing gas, carrier gas, and loop gas can be connected to more gases for more complex experiments, such as TPR/TPO cycles.

9. The mass spectrometer port and integrated software can simultaneously perform detection on both the thermal conductivity detector and the mass spectrometer.

10. The steam generator can perform steam adsorption reactions, such as pyridine, benzene, and water.

11. The cold bath can start the reaction under low temperature conditions, which meets the research requirements for noble metal catalytic reactions.

12. Hardware advantages:

The HL1800 series chemical adsorption instrument is made of stainless steel, with fully automatic control of flow and pressure, and real-time monitoring of reactions through the software interface. The temperature controlled stainless steel pipeline provides an inert and stable operating environment, avoiding condensation in the pipeline. The embedded microprocessor allows real-time control of the HL1800 series chemical adsorption instrument, enhancing its stability.

13.8 air intakes are capable of conducting a series of experiments such as TPR/TPO cycle testing.

14.4 high-precision, independently calibrated mass flow meters provide highly accurate, program-controlled gas flow control. Ensure baseline stability and accurate measurement of gas volume.

15. The analysis gas can be introduced into the carrier gas through a precise fully automatic six way valve. Equipped with calibrated injection diaphragms, the analysis gas can be injected into the carrier gas using a syringe.

16. The high-sensitivity linear thermal conductivity detector (TCD) can detect subtle concentration differences in gas before and after flowing through the sample tube. The corrosion-resistant detector filament is at a constant temperature to prevent heat loss.

17. Various customizations can also be made according to customer needs
