Automated analyser for monitoring trace amounts of volatile chloro-organic compounds in recirculated industrial water

Automated analyser for monitoring trace amounts of volatile chloro-organic compounds in recirculated industrial water

An automated analyser of volatile chloro-organic compounds in water was constructed and tested using standard mixtures of dichloromethane and dichloroethane. It was based on continuous, countercurrent gas stripping of the liquid sample followed by periodic trapping of the analytes on two traps alternately connected to the bubbler outlet, and thermal desorption. When one trap performed adsorptio...

An automated GC/MS system for the analysis of volatile and semi-volatile organic compounds in water

This paper describes a GC/MS system capable of performing Volatile Organic Analysis on liquids, solids, and air. When combined with a syringe auto-injector, the system is completely automated for both volatile and semi-volatile analyses. An OI Analytical Model 4551 Vial Multisampler and an OI Analytical DPM-16 Multisampler are interfaced and then connected to an OI Analytical Model 4560 Sample ...

Volatile Organic Compounds Monitoring for Semiconductor Foundry Clean Room Air

Air samples were collected in consecutive days using Summa canisters from semiconductor foundry clean rooms and air entrances. By coupling a NuTech preconcentrator with an Agilent GC-MS, an optimized method for qualitative and quantitative analysis of VOC compounds was developed. Method detection limit (MDL), blank spike (BS) and blank spike duplicate (BSD), etc. were estimated for method valid...
