Nitrite Analyzer – Model CA6
The Model CA-6 Nitrite Analyzer is an on-line sequential sampling analyzer, a sequence of sampling, analysis and result processing is performed and repeated using colorimetric methods. The measurement is a colorimetric analysis using an LED light source and a heated colorimetric cell designed for measuring trace amounts of analyte in water.
The colorimetric analyzer is assembled with two separated sections with two lockable doors. The bottom section is the LIQUIDS section. It includes all of the components involved in the flow, mixing and reaction stages of the sample and reagents (sampling pump, colorimetric reaction cell, reagents micro pumps,..). Numerous analysis configurations can be programmed, depending on accessories and of the number of micro pumps mounted in the Liquid Section. The top section is the ELECTRICAL enclosure. It includes the main power supply, the controller PCB assembly and the touch screen interface.
A typical Analysis Program in the Model CA-6 Nitrite Analyzer would have the following structure: Rinse the colorimetric reaction cell with the sample solution and take a sample, add one or more reagents, like a buffer or masking agent and then make the first measurement, the Reference measurement. The Reference measurement eliminates interfering factors such as sample color and turbidity, miscellaneous color from the reagents and refractive index variations.
After the reference reading, the color producing reagent(s) are added. The sample is mixed and allowed time to complete the color forming reactions before taking the second measurement, the Reading measurement. The reference and reading values are used to calculate the concentration using the calibration factor. The reaction cell is drained and rinsed several times before starting the next measurement.
Model CA-6 Nitrite Analyzer
The CA-6 can also be configured to measure: Aluminum, Ammonia, Chlorine, Chloride, Chromium VI, Copper, Cyanide, Hardness, Iron, Manganese, Nickel, Nitrate, Nitrite, Phosphate, Total Phosphate, Silica, Sulfate, Zinc
