Adaptation of a cold vapour mercury analyser to flow injection analysis
Minor modifications to a Coleman MAS-50A Mercury Analyser System allowed the determination of mercury by flow injection analysis. Using sample volumes of 600 mul it was possible to analyse up to 120 samples per hour, with a detection limit of 0.2 mug. l(-1) (120 pg) of mercury. The authors also report on a simple digestion procedure which replaces the time- and reagent-consuming EPA procedure, ...
متن کاملA versatile injection system for flow-injection analysis
Analyser injection systems based on the principle of flow-injection analysis depend on the technique used. They generally take the form of an injection loop valve; the injected sample volume is determined by the volume of the valve. Injection systems are seldom designed with a time factor to define this volume. The authors report on an original injection system, which enables the two techniques...
متن کاملA novel flow injection technique: all injection analysis.
Water quality control has become extremely important from industrial and environmental view points. Flow injection analysis (FIA) has been increasingly recognized as a valuable tool for such a monitoring system.1 However, some problems exist when FIA is used for a monitoring process. The most important problem is the consumption of large amounts of reagents and carrier solutions during continuo...
متن کاملFlow Injection Analysis: a new tool to automate extraction processes
Present needs have forced the growth and improvement of analytical methods; an area of analytical chemistry which has received a great deal of attention over the last few decades is automatic analysis, with many and varied instruments having been developed and commercialized.
متن کاملFlow injection: A new approach in analysis
The manual handling of solutions (known as “beaker chemistry”) remains the Achilles Heel of modern analytical instrumentation. It is currently being replaced by flow injection analysis (FIA), which is computer compatible and allows automated handling of sample and reagent solutions with a strict control of reaction conditions. The flow injection analysis (FIA) was preceded by the success of seg...
