PID Correction Factors, Ionization Energies, and Calibration Characteristics - Jul 05 "Can I detect TCE with a 10.6eV lamp, or do I need an 11.7eV lamp?" "What method is best for calibrating a PID?" Questions such as these are answered in our most requested technical document. Workhorse for Tough Environments - Jul 05 After a dream run in its Californian trials, QED’s new air-driven piston pump has arrived in Australia. Digital Detection of Wastewater in Stormwater - Jul 05 This paper was written by the South Gippsland Shire Council, and published in "Environmental Health" Vol.5 No.1 2005. In the paper the predecessor to the LevelTroll, the MiniTroll was used obtain the crucial data for this study. Pump Placement for Low Flow Sampling - Oct 03 Pump placement is often an issue when changing to Low Flow Sampling from traditional purging; concern is that samples will come from a narrow zone within the well screen, possibly missing contamination above or below the pump intake. However this is not the case! Read on... Measuring trichloroethylene with PIDs - May 2003 Can I measure trichloroethylene with a standard 10.6 eV PID lamp? Measuring diesel fuel or kerosene with PIDs - May 2003 Can I use a PID to measure diesel fuel or kerosene? Options for Sampling Very Low Yield Monitoring Wells - May 2003 Obtaining samples from wells set in low hydraulic conductivity formations is a challenge.
