VOCs

Highly Integrated
The PAMS analysis unit and the non-methane direct measurement analysis unit are integrated into a unified cabinet, featuring a highly integrated design that significantly reduces the space occupied by the equipment.

No Liquid Nitrogen Required
Utilizing Stirling cryogenic technology, the system operates without liquid nitrogen, directly enriching PAMS components and non-methane organic compounds at -130°C.

Non-Methane Direct Measurement Method
The system employs deep cold focusing combined with a direct method to measure non-methane total hydrocarbons, eliminating the need for a differential method, and making it suitable for monitoring trace levels of non-methane total hydrocarbons in ambient air.

DEANSWITCH Technology
The system utilizes deep cold focusing combined with DEANSWITCH central two-dimensional cutting technology for analyzing PAMS components.

Maintenance-Free
The Stirling cryogenic unit does not contain adsorbent packing, thus there is no need for later replacement of the cold trap.
