The patented Series 5000 Silica Analyzer is an on-line instrument using the silicomolybdate/heteropoly blue method of analysis for colorimetric measurement of silica at a wavelength of 810 nm. The measurement range is 0.00 to 5000 micrograms/liter (µg/L or parts per billion) as reactive silica (SiO2). Accuracy is ± 1 µg/L or ± 5% of reading, whichever is greater for the 0 to 500 µg/L range and ± 7% of reading for the 500 to 5000 µg/L range. The minimum detection limit is 0.5 µg/L. The analyzer provides a digital display of concentration and is autocalibrating.

Features and Benefits of the Series 5000 Silica Analyzer

Sample failure alarm automatically shuts down and restarts analyzer when sample flow is interrupted

Continuous auto-zero on each sample analysis prevents interferences

Self-diagnostics alert the operator to any abnormal conditions in the instrument

Grab samples without interrupting normal sample flow

Low reagent consumption and pressurized reagent delivery system reduce maintenance requirements

Three choices for calibration, including programmable autocalibration
