Overview

The sales gas sampling bag is suitable for filling various gas samples, such as sulfides, halides, and organic gases. Gas sampling bags are widely used for gas sample collection and preservation in industries such as petrochemicals and environmental monitoring. Characteristics of gas sampling bags: low permeability, good airtightness, low adsorption, and stable chemical properties.

Product Details

Selling gas sampling bags The usage method is as follows:

1. Press and hold the lid of the gas sampling bag valve with some force, then rotate the lid clockwise to press the silicone pad inside to the innermost position.

2. Valve closed: Rotate clockwise to the end; Valve opening: Rotate counterclockwise approximately once from closed to open;

3. There is a sampling hole on the top cover, with a built-in silicone pad that can be punctured for sampling, with high sampling accuracy. Suggest inserting needles about 15 times and replacing the silicone pad

4. The default gas sampling bag valve J is equipped with silicone tubing sizes of 3 * 5mm and 4 * 6mm; 5* 7mm, 6*9mm。

5. When filling standard gas or sampling, it is advisable to replace it with pre installed gas three times.

6. The gas sampling bag can be reused and needs to be cleaned with pure air or high-purity nitrogen or pre packaged with gas for storage and use. Keep away from open flames and high temperatures to avoid piercing with sharp objects.

7. The recommended inflation pressure for gas sampling bags should not exceed 20KPa.

Selling gas sampling bags

We recommend the following guidelines for the proper use of gas sampling bags:

before sampling

Store unused bags in a clean environment and pack them in a sealed outer bag to prevent the adsorption of pollutants.

Rinse with high-purity nitrogen before use and pre clean the sampling bag.

The leakage rate should not exceed 0.1 "Hg/min.

during sampling

Do not extract more than 80% of the gas from the bag.

Ensure to use clean PTFE tubing to connect the airbag.

Use a vacuum box sampler to sample the sampling bag to avoid contamination of the sampling pump.

The typical flow rate is 3 L/min.

After sampling

Due to the risk of sample adsorption on the airbag, the airbag should be used once.

The storage time usually does not exceed 48 hours, unless the validation study proves that the sample has longer stability.

Avoid direct sunlight and store at 0 ° C or above to prevent condensation.

Transport in rigid opaque containers to prevent puncturing of airbags.
