Single Cold Trap Atmospheric Online Concentration Sampler, ZTD-1 (CAT#: STEM-C-2738-ZJF)

The ZTD-1 Single Cold Trap Atmospheric Online Concentrator is designed for:
Qualitative and quantitative analysis of VOCs in key monitoring areas and factory boundaries.
Continuous monitoring of ozone precursors (PAMS57).
Simultaneous detection of various types of compounds such as alkanes, nitrogen- or oxygen-containing aldehydes, ketones, esters, halogenated hydrocarbons, and sulfides.
Typical monitored compounds include benzene derivatives, acrylonitrile, acetone, methanol, methyl mercaptan, epichlorohydrin, m-xylene, dichloroethane, and vinyl chloride.

Utilizes semiconductor cooling for flexibility and convenience.
Employs imported high-inertness deactivation tubing for all sample transfer lines, ensuring no residue or cross-contamination, thereby guaranteeing the repeatability and accuracy of sample injection.
Equipped with high-temperature six-way valves, with a maximum operating temperature of 240°C (customizable up to 330°C).
The connection points between the six-way valves and the transfer lines are located within a heated insulation box, eliminating transfer cold spots and ensuring sample integrity.
Six-way valves are motor-driven for ease of use.
Features a full Chinese LCD display for simple and convenient operation.
Comes with a universal drive interface, allowing connection to chromatographs from various domestic and international brands, enabling automatic startup of chromatography and workstations.
