Atmospheric pre concentrator (free of liquid nitrogen)

BCT 990MTAtmospheric pre concentrator (free of liquid nitrogen)Adopting an electronic refrigeration three-stage trap design, it can pre concentrate volatile and semi volatile organic compounds such as polar, non-polar, active sulfur, and nitrogen compounds below C20 in the sample. After concentration and removal of substances such as water, N2, CO2, etc., the sample is subjected to thermal desorption focusing for gas separation and detection. With one injection, hundreds of VOCs can be accurately detected.

• Liquid nitrogen free design

Dual tank metering technology

Not affected by sample matrix - using pressure measurement method, abandoning traditional MFC measurement, pressure measurement is not affected by sample matrix, and any matrix measurement is accurate.

Wide injection range - The dual tank design has high injection accuracy, with a standard injection range of 5-1000ml. It has high accuracy for both high concentration small volume injection and low concentration large volume injection.

Fast injection speed - The injection flow rate is automatically adjusted, with a flow rate as low as 5ml/min or below. The injection flow rate can achieve a capture flow rate of over 150ml/min, with an injection volume of 300ml and an injection time of less than 3min.

• Independent focusing trap

Injection without diversion - independent focusing trap, no diversion loss during injection, improving detection limit level.
