Screening for 57 odorous substances in drinking water using SPME ARROW

CTC Analytics AG
14 Apr 2021

This application note describes the routine screening method for 57 odorous compounds in drinking water. It uses the versatile SPME ARROW extraction on a PAL RTC System to screen and quantify odorous substances in drinking water. The entire process of online extraction of water samples, enrichment, and injection can be automated without manual intervention. The significant reduction of organic solvents used improves the operator safety, making this automated method an important contribution to green analytical chemistry.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Quality ControlQuality control is needed in all production processes. Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria.
