Mobile Laboratory Services

ACT’s Mobile Laboratory includes Gas Chromatographs, Photoionization Detectors, Multi-Gas monitors and Infrared Spectrophotometers. With our trained personnel and equipment, we can analyze vast numbers of samples as they are collected in the field. The data generated can be utilized for real-time tracking of contamination and the identification of additional sampling locations. It can also be utilized to select appropriate samples for confirmatory analysis or to locate conventional monitoring wells or vapor points.

mobile2Gas Chromatographs

Utilizing our SRI 8610C Purge and Trap Gas Chromatograph, we can perform a wide variety of volatile and semi-volatile organic compound analyses in the field on any sample matrix: soil, soil-vapor or ground water. Your results will be immediately provided to you in the form of a computerized laboratory data sheet, most often even before your next sample has been obtained. The detection limit of the 8610C is generally about 1.0 parts per billion for soil-vapor or ground water and 10 parts per billion for soil. The standards utilized in the 8610C include the full array of volatiles found in the EPA Methods 601, 602, 8010, 8020 and 8021 analyses.

Infrared Spectrophotometers

The Miran 1A CVF Infrared Spectrophotometer allows for the detection of total petroleum hydrocarbons in either a soil or ground water sample. Petroleum hydrocarbons are identified utilizing a modified version of EPA Method 418.1. In addition, the Miran 1A CVF can perform a scan in any range of the infrared spectrum. The detection limit of the Miran 1A CVF is 0.1 milligrams per kilogram for soil and 0.1 milligrams per liter for ground water.

Photoionization Detectors

Our ppbRAE and Microtip Photoionization Detectors (PID) provide instantaneous qualitative data regarding the total organic vapors of soil or soil vapor samples. The detection limit of the PID is as low as 1 part per billion and it can identify vapors at concentrations up to 10,000 parts per million. By utilizing the alarm feature, we can compare the results to a standard set by either you or a regulatory agency that can be utilized as a “cut off point” for investigatory or remediation requirements.
