HJ 732-2014 Sampling Bag Method for Volatile Organic Compounds in Fixed Source Exhaust Gas

HJ 38-2017 "Determination of Total Hydrocarbons, Methane and Non Methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources by Gas Chromatography Method"

2、 Product Usage

The XA-12 intelligent vacuum bag sampler is a professional instrument that uses passive sampling method to collect various gas samples, especially suitable for sampling volatile organic compounds. It can be used by departments such as environmental protection, health, labor, security, military, scientific research, education, etc. for the collection of various gas samples.

3、 Performance characteristics

1. Small size, light weight, easy to carry, simple operation, and adjustable flow rate.

2. The transparent box is convenient for observing the real-time situation of the sampling bag and is equipped with an aluminum alloy protective box.

3. The vacuum box is used for positive pressure evacuation and negative pressure collection of gaseous samples. The sampled gas does not pass through the sampling pump, and the entire sampling process is not affected by the sampling equipment. The collected sample is the original gas sample, and the sampling speed is fast, achieving zero cross contamination sampling.

4. The gas path uses chemically inert materials to ensure that the collected gaseous samples are free from cross contamination and adsorption.

5. Equipped with a high-performance lithium battery, it can be used for both AC and DC, and can be optionally equipped with a heated flue gas sampling tube.

6. The instrument has a reverse rotation function, and the replacement of residual gas in the airbag and the entire gas sampling process can be completed through the conversion switch on the instrument panel;
