ZY-01Type online atmospheric pre concentration device

1、 Instrument Introduction

To meet the requirements of the online monitoring system for volatile organic compounds in the supporting environment airVOCThe detection limit of s has been reachedppbLevel, independently developed and launched by the companyZY-01Type online atmospheric pre concentration deviceIt can seamlessly integrate with online monitoring systems from various manufacturers.

2、 InstrumentCharacteristics and main functions

1. Color touch screen display, controlled by microcomputer program, with main functions including:

⑴ Method parameter setting, real-time display of working status, and running time;

⑵ The desorption zone, injection valve, sample transfer tube, and secondary desorption zone are all separately heated and temperature controlled;

⑶ Load the applicable analysis program and automatically complete the processing of the entire sample;

⑷Can be increased according to user needsDouble cold trapcomponent；

Equipped with dual interfaces: receiving sampling system output signal interface and sending start signal interface;

2. Adopting electronic refrigeration technology, convenient and practical;

3Through time programming, automatic functions such as adsorption, desorption, low-temperature secondary adsorption, desorption, injection, and blowback cleaning can be achieved;

4The sample transfer tube and injection valve treated with inertization have automatic blowback function, which avoids cross contamination of different samples;
