Geoprobe - GeoProbe Services
Currently, Direct Push Analytical has multiple Geoprobe® model units available for use on your projects. Two units are Geoprobe® Model 5400’s, mounted in 4-wheel drive trucks. Geoprobe® Model 6600DT Series Track Mounted, and is one of the largest probes that Geoprobe® makes. The 6600DT Series Models are 48-inches to 60-inches wide and 13 feet high when fully deployed and offer exceptional maneuverability and accessibility when setting wells in confined areas (ie. gas stations). We also have a Geoprobe® mounted on a hand cart (i.e. dolly) that can access entranceways with a minimum 32.5 inch width.
Mobile Lab Services
One of the most practical services available to environmental projects with time constraints or a high number of samples to be analyzed is Mobile-laboratory service. On-site gas chromatography analyses for volatile and semi-volatile organic analytes is available through Direct Push Analytical`s mobile laboratory associates with NELAC accreditation, the `gold standard` in laboratory certification. Mobile-laboratory service provides projects with the service and quality of a fixed-base laboratory, but without the associated time delays. Direct Push Analytical and its mobile-laboratory associates can provide “real-time” analysis of air, water, soil, and hazardous waste samples. Within just a few hours of arriving on-site, chemists can be producing screening data in support of site investigations or fully defensible data packages suitable for site closure, dependent on client needs.
MIP Services
In general, the Membrane Interface Probe (MIP) system has the ability to detect concentrations of Volatile Organic Constituents in the soil down to concentrations of roughly 200-500 ppb, depending on the compound and the detector used for the analysis. The results obtained from the MIP system are only semi-quantitative as each chemical has a different transfer rate across the MIP membrane and each compound reacts differently in different sub-surface mediums. This transfer rate simplistically relates to: the volatility of the compound, the solubility of the compound, it’s concentration in the surrounding lithology, the permeability of the material in contact with the probe, the gas flow in the MIP system, the status of the membrane.
