FAQs

What types of gases can I collect with Xin Tester Aluminum Foil Gas Sampling Bags?

These bags are ideal for collecting chemically stable and low-reactivity gases, such as inorganic gases (CO, CO2, N2, etc.) and ambient air samples for environmental monitoring. The premium multi-layer film ensures low permeability and sample purity. Please note: they are not recommended for non-methane hydrocarbon detection or highly corrosive gases that may react with the aluminum layer.

How do I choose between the Single Valve and Double Valve configurations?

It depends on your sampling procedure. A Single Valve is perfect for standard one-way gas collection or extraction. A Double Valve is recommended for applications requiring gas displacement or continuous flushing; it allows you to inlet gas through one port and outlet through the other, ensuring the most representative sample of the target environment.

What are the pressure limits and safety precautions for using these bags?

To ensure safety and prevent leakage, the maximum recommended inflation pressure is 3KPa. Over-inflation should be avoided as it may damage the heat-sealed edges. The bags should be operated within a temperature range of -20°C to +65°C. To open the PP valve, simply rotate it 1/2 turn anticlockwise. Always keep the bags away from sharp objects and open flames.

Are these sampling bags reusable, and what is the best way to store them?

For high-precision laboratory research, we recommend using a new bag to avoid cross-contamination. For general industrial use, they can be reused if thoroughly cleaned and flushed with high-purity nitrogen or clean air. When not in use, store the bags flat in a cool, dry environment, avoiding direct sunlight and heavy pressure.
