Water/Wastewater 29 available and solar cells or other sources are used.
On the ATMS 600 series, all electronics are included on a microprocessor card and a PC is only needed for input and output data and graphical presentation. Normally a laptop or network is used for such purposes. The ATMS 600 consists of one cabinet only, with the cell system and a metal enclosure with the microprocessor card inside.
An extension of the ATMS 600 is an ATMS using a dual measuring cell system, called ATMS 600D. This enables one to measure two systems using different experimental conditions.
The advantages of the ATMS 600 are:
•Higher stability over time by using a micro processor card instead of the PC-processor
•Simpler maintenance as the micro processer card is the only part that may need to be replaced
•Increased sensitivity because Square Wave Voltammetry is used •Less weight with one cabinet only
•No computer is needed except for input and output of data and data analysis. For that purpose a laptop PC is included in the system, but this can be removed during installation
•The use of 12V DC is convenient if electricity is not available. If electricity is available, a simple adapter to 12V DC can be used

New Communication Option for Water Quality Loggers
Innovative water quality instrumentation company, Intellitect Water (UK), has increased the flexibility and compatibility of its flagship product, the Intellisonde™. An optional voltage output card can now be fitted internally to enable data communication with PLCs and other dataloggers.
Commenting on the announcement, the company’s Operations Director John Howell said, "Many of our clients already have data-logging and communications infrastructure in place so they do not need to utilise RS232 or GPRS. Instead, the new output card provides a voltage signal for each of the sensors, which further helps to lower the cost of water quality monitoring."
The Intellisonde™ features up to 12 sensors in a tiny sonde head that inserts directly into a pipeline, logging water quality data and providing remote access to the data through a variety of communication options.
The optional Analogue Output Card provides up to 12 channels (0 to 2.5V) and can be fitted on request to allow simple connection to other data-loggers and programmable logic controllers.
Uniquely, the Intellisonde™ technology offers utilities the ability to monitor water quality in the many thousands of miles of pipe that carry water to industrial and domestic consumers. This reduces the cost of water treatment, improves water quality and aids the management of water distribution networks.
Reader Reply Card no 99 Determination of Total Phosphorous in Wastewater
Dionex (USA) is pleased to announce the release of an application on the determination of total phosphorous in wastewater. Application Note 254: Determination of Total Phosphorous in Wastewater Using Caro’s Reagent and Ion Chromatography describes two IC methods, one with simple carbonate/bicarbonate eluent preparation and a second method that uses generated potassium hydroxide eluent and has the high reproducibility of an RFIC™ system.
Phosphorous in the environment is beneficial for many biological processes, but too much phosphorous can create an imbalance in the ecosystem. Monitoring the concentration of phosphorous in the environment is a good indictor because higher than normal concentrations lead to environmental problems. AN 254 demonstrates accurate measurement of the total phosphorous content of a wastewater sample using a Reagent-Free™ IC (RFIC) system with all its benefits, including excellent retention time reproducibility for accurate peak identification, and time and labour savings by eliminating eluent preparation and associated errors.

Chromatotec (France) is pleased to announce a new analyser system for the surveillance of VOCs in water, which is named airmoPURGE.
The sample preparation technique is based on US EPA method 502.2 for purging the VOCs from water using an inert gas, followed by their analysis using our certified airmoVOC C6-C12 analyser.
There are many applications for this technique including the analysis of raw
source water, seawater, rain water and also for the analysis of finished drinking water. Headspace analysis is available for analysis of wastewater.
It should be noted that the analysis system used in this application can also optionally measure VOCs in ambient air i.e. the concentrations of VOCs in both air and water can be measured using this one single system!
