MIP (Membrane Interface Probe)

MIP (Membrane Interface Probe)

The MIP measures:

• Volatile petroleum hydrocarbons

• Solvent contamination

• Soil electrical conductivity

• Soil permeability

Working Principle:

• Inert carrier gas continuously flows over the heated membrane in the probe.

• The gas is then transported to a series of surface detectors.

• Each detector responds to specific contaminant characteristics, enabling MIP operators to identify contaminant groups (e.g., petroleum hydrocarbons vs. chlorinated solvents), and map contaminant plumes from source to dispersion zones.

Applications:

By analyzing soil conductivity, permeability, and contaminant data, investigators can determine whether volatile organic compound (VOC) contamination is:

• Adjacent to primary migration pathways (e.g., groundwater flow channels).

• Trapped within accumulation zones (e.g., low-permeability layers).

This information is critical for designing effective in-situ remediation strategies.
