How does turbidity meter work?
What is turbidity meter? Turbidity meter, also known as turbidimeter, is mainly used to analyze water or solution turbidity level of water quality testing equipment. A Turbidity meter is a tool with optical properties due to the dispersion of light, which can be expressed as the ratio of reflected light to incident light. All other things being equal, the intensity of light reflected from the ...

Save time and money with Metrohm Inline Sample Preparation solutions
Why is sample preparation prior to separation essential for your analysis? When using ion chromatography (IC) as an analytical technique, samples often cannot be injected directly onto the separation column. There are several reasons for this: samples may contain particles or colloids, the analyte concentration can be too high or low, the sample matrix is unsuitable for a direct injection, or the ...

Multigas analyzer supports liquid fuel research - Case study
Two advanced FTIR analyzers are being employed to monitor multiple gas concentrations simultaneously in laboratory scale reactors at Sasol’s Research and Technology Centre in South Africa. The monitors, which were supplied by Gasmet Technologies (Finland), are being used to study changes in gas composition as gas passes through the reactor of the Fischer–Tropsch process – a key ...

Screening technique to estimate high benzo[a]pyrene concentrations near roads
The emission factors of benzo[a]pyrene for gasoline cars and for diesel cars were measured by directly collecting the exhaust gas using a portable sampling equipment and became 660 ng km–1 and 1700 ng km–1, respectively. The regression equations to easily evaluate the concentrations at the roadsides and at the crossroads were introduced as the functions of building height, road width, ...
