Silica Analysis in Boiler Feed Water

The latest addition to the Alert Colorimeter range from Applikon Analytical is the new colorimetric Silica analyzer. Designed for reliability and minimal operator attendance the Alert analyzer is perfect for boiler feed water analysis.

The analyzer utilizes the unique Differential Absorbance Colorimetry (DAC) methodology to prevent reagent colour interfering with the analysis result. The Alert Colorimeter is available in two ranges, 0 - 50µg/l and 0 – 1mg/l. The detection limits are 0.5µg and 0.001mg respectively.

Automatic calibration checks are carried out either on a periodic basis or as a conditional action to validate out of range results. The Alert Colorimeter features extensive I/O capabilities such as high result relays, remote start/stop and analogue outputs. Multistreaming units for up to six sample streams are also available.

The running costs are kept to a minimum by low reagent use, using 0.5ml of each reagent per analysis, and minimal consumables. Attendance for planned maintenance is usually carried out on an annual basis.
