Electronic Refrigeration Pre ConcentratorIt is an analytical device that uses multi-stage cold trap technology to achieve sample concentration and impurity separation, mainly used in fields such as environmental monitoring and laboratory analysis.
The electronic refrigeration pre concentrator adopts semiconductor electronic refrigeration and rapid thermal desorption technology. Composed of electronic refrigeration, injection valve, cold trap, mass flow meter, and pump, it can pre concentrate volatile and semi volatile organic compounds with carbon numbers below C20 in the sample, including polar (aldehydes, alcohols, esters, ketones, ethers), non-polar, active sulfur, nitrogen compounds, etc., and effectively remove H2O, CO2, N2, and inert gases from the gas sample.
Operation process:
Software control: All operations are controlled by computer software, and parameters (such as temperature, speed, time) are set through a touch screen to monitor the concentration process in real time.
Preparation for startup: Check if the power cord and data connection cable are intact, and ensure that the door cover is completely closed.
Operation monitoring: Observe whether the instrument reaches the set vacuum degree, speed, and temperature, and promptly shut down for troubleshooting in case of abnormalities.
Maintenance points:
Vacuum pump maintenance: Regularly check the oil level and quality. If the oil is cloudy or insufficient, it needs to be replaced or replenished.
Cleaning of the cavity: Clean the residual solution in the sample chamber after each use to avoid corrosion of the components; Wipe the outer shell with a warm water soft cloth and avoid using organic solvents.
Regular inspection: Check the aging condition of the sealing ring every month, clean up pipeline blockages, and ensure normal gas flow.
