Analytical Method for Determination of the Solution Color of Raw Sugars, Brown Sugars and Colored Syrups at pH 7.0 (According to ICUMSA Method GS1/3-7)
Method: Spectrophotometric Color Determination at 420 nm Zero adjustment For each measurement series, a zero adjustment is required. It is recommended to use the same cell for zero adjustment and for sample measurement. The zeroing procedure for the measurement series is automatically prompted by
Ultrasensitive Determination of Silicate in Process and Boiler Water Using Rapid Photometric Tests
Efficiency of industrial plants and equipment constitutes one of the basic preconditions for sustainable economic operations. One avoidable problem is posed by the undesirable build-up of deposits, i.e., scale – in pipes, boilers, and turbines, whose principal cause is silicate.
