Residual Gas Analysis

by Hiden Analytical     based in Warrington, UNITED KINGDOM

Residual Gas Analysis is a general term for the analysis of gas and vapour species in vacuum chambers and vacuum processes. The Hiden RGA series quadrupole mass spectrometers provide for routine, fast, wide dynamic range residual gas analysis, measuring the partial pressures of the species that are critical to vacuum quality and process requirements. Applications include: vacuum chamber leak detection vacuum quality measurement and monitoring virtual leak detection outgassing studies bakeout cycle/vacuum pump down monitoring

Analysis of VOC compounds in water by Purge & Trap or dynamic headspace

by Chromatotec Group     based in Val de Virvée, FRANCE

Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA – “Volatile organic compounds in water by purge and trap capillary column gas chromatography with photoionization and electrolytic conductivity detectors in series – Revision 2.1”. - 524.2 method from US EPA – “Measurement of purgeable organic compounds in water by capillary column gas chromatography/mass spectrometry – Revision 4.0”.

Measurement solution for FTIR Vs. GC in gas analysis

by Protea Limited     based in Middlewich, UNITED KINGDOM

Comparison of Technologies

A gas chromatograph (GC) has traditionally been the technology of choice for laboratory analysis of gas samples. GCs have been used for over 50 years in the qualification and quantification of complex mixtures of gases. The techniques and methodology required to run GCs are often a pre-requisite for any laboratory technician. Recent developments in Fourier Transform Infra-Red (FTIR) gas analysis has enabled this technology to start to replace GCs in the lab.

Odor Control for Asphalt

by OMI Industries (OMI)     based in Long Grove, ILLINOIS (USA)

Control Asphalt Odors Naturally

The production of hot mix paving asphalt generates odors that can be strong, persistent, and a nuisance to employees and neighbors alike. Controlling and abating these odors can be a challenge.
