With the availability of a wide range of field-portable
instrumentation the market for them is slowly but surely emerging. This
approach is quietly getting accepted as it has made possible performing
high-quality and rapid analyses at the site of investigation itself. There
is off course much ramifications in the nature of business and logistics
involved before a lab becomes truly portable. Before we go further in
discussing the challenges of field- portable instrumentation it would be
prudent enough to understand what is exactly a field-portable
instrumentation
What
is Field-Portable Instrumentation?

The
answer is it refers to the instruments which is fast, lightweight, small
enough to carry, functions on a simple infrastructure and lastly, is adept
in generating laboratory quality data. Each of these factors is crucial.
To cite an example, say an environmental laboratory conducts on site
analyses. The objective of such analysis using field- portable instrument is
that it should be capable of generating effective data. This translates into
the fact that the data quality generated should accomplish the data quality
objectives (DQOs) of the project. If it fails in this endeavour then there
is no use of it Some of the categories of instruments which falls under the
ambit of field-portable instruments include the follwing.
- Gas chromatographs(GCs) and micro-GCs,
- Mass spectrometers(MS)
- Continuous flame ionization detectors (FIDs)
- Photoionization detectors(PIDs)
- Extractive Fourier transform infrared (FTIR) spectrometers
- Filter-based and other infrared (IR) spectrometers
- Xray fluorescence (XRF) spectrometers
- Selective monitors
- Hand-held Raman Spectrometer to be used for organic solids and
liquids
