Introduction Portable VOC (Volatile Organic Com- pound) analyzers have been widely used in the identification of fugitive emission sources, a process commonly called "screening." Screening is important both in research to develop emission factors and in proposed regulatory monitoring of fugitive emissions.

Response of portable VOC analyzers to chemical mixtures Author: D A DuBose ; G E Brown ; G E Harris ; Industrial Environmental Research Laboratory (Research Triangle Park, N.C.). The sensitivity of the analyzer was characterized by a response factor, which was defined as the ratio of the actual chemical concentration to the observed instrument response.

Bag samples of known concentration were prepared by introducing a measured weight (or volume) of the subject chemical into a Tedlar bag containing a known volume of hydrocarbon-free air.

In this paper, chemoselective response dyes were employed as probes to capture VOCs, including a novel chemoselective response dye called BODIPY.

The spectral data of distinct sensor color difference pattern due to the rapid chemical reaction between the dye molecule and organic compound molecule was collected by portable Visible-Near Infrared Spectroscopy (Vis-NIRS) Hao Lin, Yaxian Duan, Song Yan, Zhuo Wang, Muhammad Zareef.

This book is ideal for chemists, industrial hygienists, toxicologists, safety engineers, emergency responders and others responsible for assessing chemical threats from volatile compounds.

The ideal chemical sensor is an inexpensive, portable, foolproof device that responds with perfect and instantaneous selectivity to a particular target chemical substance (analyte) present in any desired medium in order to produce a measurable signal output at any required analyte concentration.

Field chemical analysis (FCA) of volatile halogenated hydrocarbons is a highly debated topic of widespread interest due to the significant negative impact of these compounds on public health, on ecosystems and in the environment (e.g. destruction of stratospheric ozone).This article reports, for the first time, the use of a unique, lightweight (11 kg), man-portable membrane inlet mass.

Portable Emissions Analysers Portable FTIR and TDL emissions analysers from Protea allow for a wide range of industrial pollutants to be measured periodically or as a back-up to existing CEM systems. VOC products are harmful to environment. Leaks often occur in cooling towers / heat exchangers, run-off water, waste water, and bilge water.

By using a process analyzer to continuously measure for VOCs, the user can save hundreds of thousands of dollars in lost product, help protect the environment and prevent possible explosions if the leak is large enough and the VOC reaches LEL. Fixed gas. HazMat incidents do not often involve a single chemical, but may involve a compound that is a mixture of toxic chemicals.

This “witches’ brew” of toxic compounds requires greater care in determining alarm setpoints. If the mixture is identifiable, then the individual. As stationary or portable gas analysers for sampling or continuous gas analysis, they are available for a wide range of technical gases and applications.

Witt offers gas analysers for example for oxygen, carbon dioxide, helium, hydrogen or methane. The gas analysers are used, for example, in food and pharmaceutical industries.

the sample/water mixture. The PID response is measured within 2 - 3 sec of puncturing the foil liner. The sample response is compared to a working standard containing the principal volatile contaminant of concern at the site or in the waste, and an estimate of total VOC concentration is calculated.
