Portable carbon dioxide CH4 analyzer for soil gas sampling

Portable carbon dioxide CH4 analyzer for soil gas sampling

1. Introduction: The idea of drawing conclusions about substances in soil from soil gas analysis comes from petroleum exploration. Currently, soil gas analysis is mainly used to evaluate contaminated sites and their remediation. On the one hand, it is used for pre identification and preliminary investigation to determine pollution priorities. On the other hand, soil gas monitoring can be used during the implementation of remediation measures, and post remediation checks can also be conducted through soil gas analysis.

Another key focus of soil gas analysis is to control landfills.

The significance of soil gas analysis is determined by the sampling type. In principle, the sampling system should have a flexible structure and be adjustable for use according to different sites.

These requirements can be met through Meta's soil gas sampling system BLPS 404. It can perform representative and reproducible sampling analysis of soil gases.

Product Description: How to Translate

BLPS 404-CH4 is a portable soil gas sampling system that enables repeated sampling of soil gas, providing relevant gas information for soil surface biological status and soil remediation.

This instrument can be configured according to the CO of the sampling system itself₂,O₂,CH₄And H₂The soil basic parameters (persistent gases, GB/T 36198-2018) measured by the S sensor are used to determine the soil gas sampling time.

This instrument can also achieve clustered (adsorption tube) and non clustered (headspace bottle) sampling, and can be directly connected to the manufacturer's portable GC chromatographic analyzer to measure TVOCs and benzene derivatives (volatile organic compounds VOC, GBT 36198-2018) in soil gas.

Main purpose:

This instrument can be widely used for daily soil monitoring, monitoring of polluted areas, and exploration of polluted areas.
