Online Analyzer For Phosphate Measurement

June 30, 2011
The easy-to-use and economical CA-6 Online Analyzer from Electro-Chemical Devices uses colorimetric analyses to accurately and reliably measure phosphate and total phosphate levels.
The CA-6 Analyzer is available in models measuring phosphate at 0-5.0 mg/L, 0-50.0 mg/L or 0-200 mg/L and total phosphate at 0-2.0 mg/L, 0-20.0 mg/L or 0-100 mg/L. Phosphate and total phosphate levels are important indicators of water quality. Sources of phosphates include sewage, industrial waste and fertilizers. Excessive phosphates can lead to extensive algae growth called "blooms" which can have serious ecological consequences. The CA-6 precision online sequential sampling analyzer is lightweight and easy to install. Weighing less than 40 pounds, it can be wall mounted or simply set on a bench using the optional Bench Top Stand. After the sample, waste and reagent lines have been connected to the analyzer and provided with power, the CA-6 will begin its preprogrammed analysis sequence. The CA-6 is available with up to 4 channels (optional) each from a separate sample point. A simple, user-friendly menu structure and touchscreen interface makes it easy to access information or customize analyses. The CA-6 utilizes photometric differential absorbance to analyze over 20 other common parameters in addition to phosphate including: aluminum, silica, nitrogen, iron and sulfate. It operates at a wide temperature range of 5-50°C and offers repeatability of ±2% on the absorbance value if the turbidity <80 NTU and drift of ±2% per month on the absorbance measurement. The highly accurate CA-6 Analyzer improves ISE measurements requiring significant sample conditioning for measurement accuracy, reducing the volume of conditioning chemicals required and minimizing the associated waste. With the CA-6, the result is a faster, accurate measurement requiring fewer consumables with less waste to reduce overall operating costs-saving labor and money. The CA-6 Analyzer's easy-to-use touch-screen display shows the measured parameter, analyzer status, percent reagent volumes, time and the menu bar, which provides access to the Run, Display, Program, Service and Help menus. It includes two alarm relay outputs and a 4-20 mA channel that connects with PLC's or distributed control systems. The rugged and reliable CA-6 features two separate compartments to isolate liquids and electronics and is enclosed in an epoxy powder coated, cold rolled steel cabinet. The liquids enclosure houses all the components necessary for sampling and reagent flow, mixing and reaction stages (sampling pump, reagent micro-pumps and colorimetric reaction cell). The electronics enclosure contains the main power supply, the controller printed circuit board assembly and the touchscreen interface. It is easy to use the CA-6 to create customized analysis routines and access results via the touch-screen unit's simple menu structure and function commands. It can be programmed with numerous analysis configurations, depending on the accessories and the number of micro-pumps mounted in the liquids enclosure.
