Product details
Product Overview
The Pre 3900 atmospheric pre concentrator adopts a three-stage cold trap design, using liquid nitrogen as the refrigerant to quickly reduce the temperature of the cold trap to -196 ℃. Combined with intelligent algorithm control, it reduces the consumption of liquid nitrogen. All sample flow paths are treated with inerting, suitable for the analysis of trace multi-component VOCs in the atmosphere, meeting the requirements of EPA TO-14A/15A and HJ 759 standards.
Product Features
Rapid cooling
Liquid nitrogen goes directly to the cold trap and can be quickly cooled to -196 ℃. The intelligent temperature control algorithm saves liquid nitrogen consumption.
high-throughput
Standard configuration includes 11 injection positions and can be equipped with an additional 3 16 position automatic injectors, supporting up to 59 continuous injection of Su code cans.
Wide range
The injection method can be quantitative ring or vacuum tank, with an injection volume of 1-2000 mL, which can flexibly handle the analysis of ppt ppm level samples.
Accurate sampling control
Adopting a high-precision proportional valve combined with a vacuum tank injection method, there is no need to worry about the influence of sample matrix on the injection volume.
Friendly human-computer interaction
The instrument adopts a rotating control screen design, which is convenient for viewing the real-time status of the instrument, and can also perform quick leak detection, system cleaning and other operations.
Application field
Environmental monitoring, emergency monitoring, occupational health, food processing, public health, scientific research
