  • A Portable High Speed Gas Chromatograph for Field Monitoring

    Over the last two decades a variety of portable or transportable gas chromatographs (GC) have been specifically designed for field use. Each instrument has introduced innovations that have simplified the task of on site air monitoring. Portable instrument users are well aware of the advantages of field sampling. These advantages include more representative results because there is no sample ...


  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Low Flow Groundwater Sampling Using RotaPump Inertial Lift Pump

    This article tells you how to perform low flow groundwater sampling using a portable, surface-mounted pump with no decontamination required before each use and  no chance of cross contamination between wells. An inertial lift pump moves a dedicated (stored in the well) pumping tube rapidly up and down.  A one-way valve on the bottom admits water on the down stroke and ...

  • On the suitability of Portable X-Ray Fluorescence Analyzers for rapid screening of toxic

    Abstract X-Ray Fluorescence spectrometry (XRF) has been routinely used for alloy testing, determination of Pb in paint, and determination of Cd in plastic. However, its use to screen for toxic elements in food and medicinal products has been surprisingly limited to date. While XRF is less sensitive than atomic spectrometry methods such as ICP-AES and ICP-MS, it offers a number of significant ...
