Gas sealed sampler is a device used to collect gas samples in a sealed environment, mainly for sampling hazardous media in industrial production and monitoring laboratory environments to ensure the safety and accuracy of samples. A gas sealed sampler is a device designed for safe and pollution-free collection of gas samples. Through a fully enclosed structure and specific operating mechanisms, it ensures that the samples are isolated from the external environment during collection, transmission, and storage. Its core value lies in preventing the leakage of toxic and harmful substances, avoiding sample contamination, and meeting the requirements of high-purity analysis. It is widely used in fields such as chemical, petrochemical, pharmaceutical, and environmental monitoring.
Sealed sampling mechanism: The sampler is connected to the process pipeline in a closed manner through dual valve control or quick plug interface, and uses negative or positive pressure technology to press the gas sample into the sampling bottle without the need for an open environment throughout the process. For example, in the petrochemical industry, for highly toxic gases such as hydrogen sulfide and chlorine, the sampler adopts a fully enclosed design to ensure the safety of operators.
Pressure and temperature control
High temperature gas treatment: Cooling and dehumidification devices should be equipped to avoid equipment damage caused by condensed water.
High pressure gas sampling: Made of 316L stainless steel or duplex stainless steel 2205 material, with a pressure resistance range covering 4-38MPa, meeting the requirements of high-pressure working conditions.
Low temperature sampling: Operators need to wear antifreeze gloves to prevent frostbite.
Material selection for anti pollution design: The inner wall is coated with PTFE to reduce trace element adsorption and ensure sample purity.
Blow and replace: Before sampling, blow the sampling bottle and pipeline with nitrogen to eliminate residual air or impurities.
core functionality
Sealed sampling: A sealed design that isolates the external environment to prevent sample leakage or contamination, ensuring the safety of operators and the environment.
Safety protection: Suitable for sampling flammable, explosive, toxic and harmful gases, preventing residual gas and liquid leakage through a sealed structure.
Accurate sampling: ensuring the accuracy and authenticity of sample collection, avoiding external interference, suitable for quality control and safety testing in industrial production.
