Product Overview
The Vacuum Box Gas Bag Sampler is a specialized device for collecting gas samples using the gas bag method. It is widely used in environmental protection, public health, labor safety, safety monitoring, military, scientific research, and educational fields, particularly for collecting volatile organic compounds (VOCs) and other gaseous pollutants. This device employs passive sampling through the vacuum box's negative pressure, preventing direct contact between the gas and the sampler, thus achieving zero cross-contamination. It is a reliable gas sampling tool that ensures high-quality sample collection.
Key Features
- Vacuum Negative Pressure Sampling: Utilizes the vacuum box's negative pressure to collect gaseous samples, ensuring sample purity by preventing direct contact with the sampler, thus achieving zero cross-contamination.
- Easy Gas Replacement: When replacing residual gases inside the gas bag, there is no need for manual connection and disconnection of tubes. The "directional switch" on the vacuum box easily allows for gas replacement and sampling of new gases.
- Inert Gas Circuit Design: The gas circuit uses inert materials to ensure that the collected gaseous samples are free from contamination or adsorption, preserving sample accuracy.
- High-Performance Lithium Battery: Equipped with a high-performance lithium battery, allowing for sampling without the need for an external power source, increasing convenience and flexibility.
- Wide Applicability: Particularly suitable for sampling volatile organic compounds (VOCs) and other pollutants. It is also widely used for monitoring odorous gases and other environmental monitoring tasks.
Applications
- Environmental Monitoring: Used for sampling exhaust gases from fixed pollution sources, particularly for monitoring VOCs, meeting the sampling requirements of environmental protection agencies.
- Odorous Gas Detection: Follows the "Determination of Odor in Air: Three-Point Comparison Odor Bag Method" standard for sampling odorous gases in the environment.
- Indoor Air Quality Testing: Suitable for monitoring gaseous pollutants in indoor air to ensure air quality in work and living environments.
- Safety and Monitoring: Used for gas sample collection in various environments, ensuring workplace safety, especially in chemical storage and processing industries.
- Scientific Research and Education: Widely used in research institutions and universities for gas pollution studies and educational experiments.
