Fully automatic chemisorption analyzer

Model：MPMS XL-7

Country of Manufacture: America

Date of purchase: 2016/08/03

Place: F-105, State Key Laboratory of Fine Chemicals

Main specifications and technical indicators:

1, Stable baseline and high quality data: high precision mass flow controller, the flow rate of 0-50 cm3/min in the range of thermal drift 0.08%.

2, reduce peak expansion: use 1/16 "stainless steel pipe to minimize the dead volume.

3, easy to load and unload samples: flexible mobile shell heating furnace and can load powder, ball and other samples of a variety of specifications sample tube

4, wide temperature range: room temperature to 1200°C, heating rate of 1°C/min to 30°C/min. Increase the temperature of low-temperature components up to -100℃.

5, condensation and adsorption: eliminate condensation and adsorption retention

6, Control the temperature of all pipelines and valves between the sample and the detector, accurate measurement.

Main functions and features: Sequential temperature desorption TPD programmed Temperature reduction TPR * Programmed temperature oxidation TPO * 

programmed temperature reaction TPRx pulse chemisorption * Catalyst treatment * Dynamic BET surface analysis * Pulse calibration Automatic dynamic 

chemisorption instrument integrates pulse chemisorption and programmed temperature technology functions. A wide range of chemisorption and temperature-

programmed reaction studies can be performed to obtain information on the physical properties of catalysts, catalyst supports, and various other materials. Typical applications include characterization of the structure of heterogeneous catalysts using programmed temperature techniques.
