48 Measurement and Testing Quality Control of Potable Water Through Automatic Particle Counting
PAMAS (Germany) develops, manufactures and distributes Automatic Particle Counters for fluid cleanliness control, e.g. of hydraulic or lubricating oil, fuel, pharmaceutical liquids like infusion solutions, WFI (Water for Injection) and process water. For dedicated water applications, PAMAS offers both portable and online measuring instruments. Portable instruments for water applications are the particle counters of the PAMAS S4031 product series. For online measurement of water, the PAMAS product range provides the PAMAS WaterViewer fulfilling the specific requirements for water quality control: This online particle counter is the ideal instrument for the analysis of potable water, process water, purified waste water or raw water. The PAMAS WaterViewer has been tried and tested for water applications throughout Europe for many years and has become the trusted measuring instrument for use in water treatment plants and water distribution networks. PAMAS Automatic Particle Counters (APCs) deliver faster and more accurate measuring results than turbidimeters or nephelometers. They also provide a more sensitive, differentiated measuring result: Beyond the collective amount of particles, an APC detects, counts and measures each and every single particle. In an online environment, the trending of these results shows much more interesting events.
There are various existing methods to determine whether water is clean and free from particulate contamination. In water treatment systems, both particle counters and turbidimeters or nephelometers are used for water quality control. Turbidimeters and nephelometers measure the collective amount of solid contaminants in liquids. The more turbid a liquid is, the higher the measuring value will be. Contrary to this, Automatic Particle Counters do not measure the collective amount of solid particles, they analyse size and quantity of each single particle which is part of that population in the online sample flow. The knowledge of the particle sizes is of paramount importance in water applications, as it helps to quickly identify certain types of bacteria or even a failure in the system (e.g. break-through of a membrane filter in case of an above average number of large sized particles). The Automatic Particle Counter thus gives more versatile and significant results than a turbidimeter.
One instrument of the PAMAS product range especially designed for water applications is the PAMAS WaterViewer. This unit takes measurements online and is installed as a fixed stationary instrument for water condition monitoring. The system is used for the cleanliness control of potable water, raw water and purified waste water or process water. For condition monitoring, the PAMAS WaterViewer may be connected to up to 32 measuring points. With the aid of microprocessor controlled valves, it is easy to change between measuring points and bypass connections. The PAMAS WaterViewer may be fitted optionally with an automatic Sensor Flushing Unit, the PAMAS SFU. This attachment will automatically remove mineral deposits (e.g. manganese, calcium, iron oxide, etc.) from the optical cell windows which may otherwise diminish the laser light beam. The instrument stays in action round the clock without anyone having to take care of it. The instrument configuration can be set up according to the customer’s requirements: Depending on the user- specific application, the PAMAS WaterViewer may be equipped with different particle sensors with different sensor specifications. The sensor PAMAS HCB-LD-25/25 for example, analyses particle sizes between 1 and 200 µm.

Hydrocarbon Analyser for MudLogging The Baseline®
Series 9000
Hydrocarbon Analyser offers analysis of the total hydrocarbons for
MudLogging during natural gas and oil exploration.
With an incredible range, from ppm levels up to 100% methane. The Series 9000 Total Hydrocarbon Analyser exhibits a great deal of measurement flexibility and features. The standard outputs include alarm and fault relays, 0-20mA or 4-20mA analog, or digital options, RS-232 or Ethernet. Configurations can also include components for single or multipoint analysis.
Electronic control of the fuel, air, and sample delivery to the flame ionisation detector (FID), with automatic ignition, improves safety, performance, and sensitivity. Alarms levels and calibration intervals are all programmable making this unit operable with minimal experience.
Built-in software options, navigated by a large graphical display and easy to use menu system, allow it to operate without or with and external computer.

Fast C1 to C5 Measurement Baseline®
announces the release of the PetroAlert® The PetroAlert’s®
Series 9100 Gas Chromatograph for fast
measurement of light hydrocarbons during oil and gas exploration. More specifically, measurement of C1 to C5 (methane, ethane, propane, butanes and pentanes) can be accomplished in a 30 second time period and provides a measurement range from low ppm to high percent levels.
speed and accuracy enables the geologist monitoring the site to analyse
both quantitatively and qualitatively the dynamics of the drill site. Detecting hydrocarbon gases while drilling allows for timely evaluation of the well’s potential making the mudlogging process more efficient.
Features of the Series 9100 include, fully integrated with powerful GC software, eliminating the need for an external PC, programmable touchscreen and USB interface, remote access and control, automatic calibration, internal data storage and unattended operation.
