Description

The APL-PTC series automatic blowing and capturing container is mainly used for the analysis of volatile organic compounds (VOCs) in water and soil, and can also be used for the analysis of volatile compounds in food. Compliance with standards includes "HJ639-2012 Determination of Volatile Organic Compounds in Water Quality by Sweep Capture/Gas Chromatography Mass Spectrometry", "HJ686-2014 Determination of Volatile Organic Compounds in Water Quality by Sweep Capture/Gas Chromatography Mass Spectrometry", "HJ605-2011 Determination of Volatile Organic Compounds in Soil and Sediments by Sweep Capture/Gas Chromatography Mass Spectrometry", etc.

一、 Characteristics and main functions

1. Easy operation, method parameter setting, real-time animation display of working status, fully automatic operation of 1-75 samples;

2. The injection valve, sample transfer tube, water trap, and capture tube desorption zone are all separately heated and temperature controlled;

3. Set up the analysis program, press the run button to automatically complete sample blowing and injection, and start chromatographic analysis;

4. Through time programming, automatic functions such as blowing, trapping, desorption, injection, and backwashing cleaning can be achieved;

5. Equipped with magnetic stirring function, the sample can be automatically stirred with adjustable stirring speed;

6. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;

7. It can automatically start the startup line interface of various brands of GC and GCMS, and can connect to all models of GC and GCMS at home and abroad;

8. The sample passes through a water trap to prevent water vapor from entering the capture tube, reducing the impact of water vapor on GC and GCMS;
