New Portable TOC Analyser for Municipal Water Monitoring
GE Analytical Instruments (USA) announces the new Sievers 5310 C Portable Total Organic Carbon (TOC) Analyser, designed specifically for municipal drinking water applications. This rounds out the 5310 C Series that already includes a laboratory and on-line model. All provide 12-month calibration stability, easy operation, comply with USEPA-approved methodology, and feature automated protocols such as TOC percent removal calculation. Typical applications include raw and finished drinking water monitoring for DBP compliance and optimisation of chemical addition.
GE also offers a new enhanced Inorganic Carbon Remover (ICR). Designed for longer consumable life and lower operating costs, it uses approximately 50% less acid than its predecessor. The ICR is available for all Sievers 5310 C and 900 Series TOC Analysers.
Together, the new Sievers 5310 C Portable and ICR offer a flexible solution for monitoring organics on-line, such as during a pilot project. Upon completion, they can easily be moved back to the laboratory.

New Handheld Product Line for the Measurement Of Conductivity, Dissolved Oxygen and pH
Automatic Thermoreactor for Water Quality Determination
The Lovibond® (Germany) Thermoreactor RD 125 offers tube test digestion of COD (150°C), Total Chromium (100°C),
Total Nitrogen (100°C), Total Phosphate (100°C) and TOC (120°C). Chemical digestion of samples is required for the photometric determination of COD, TOC, total phosphate and total nitrogen.
The required temperatures and reaction time can be selected by using the membrane keypad of the reactor RD 125. The unit works at three different temperatures (100 / 120 / 150°C) and three pre-set reaction times 30 / 60 / 120 minutes).
When digestion is complete, the reactor automatically switches off and gives a corresponding LED indication with short beep alarm. With the voltage switch on the back 220 V and 110 V are selectable. In addition, the RD 125 reactor is fitted with 24 holes for 16 mm diameter vials.

New In-Situ Particle Counter for Water Analysis
The PC-2200 from the Spectrex Corporation (USA), In-Situ Particle Counter, is a unique and easy-to-use instrument designed to permit thorough inspection of liquids without consuming the sample. It is ideal when critically clean liquids are needed. A laser beam permits observation of small particles by near-forward light scatter. In addition, a scanning and detection system is provided to automatically quantify the number of small particles in one cc (milliliter) of the contained liquid.
ITT Corporation (USA), announces the introduction of the YSI EcoSense®
pH100A, DO200A and EC300A instruments for the
accurate measurement of conductivity, specific conductance, salinity, TDS (total dissolved solids), dissolved oxygen, BOD, pH, mV and temperature for the lab or field in environmental and wastewater applications. ITT Analytics showcased its range of YSI EcoSense products in booth during WEFTEC 2011 from in Los Angeles, USA.
YSI, the newest member of the ITT Analytics family’s handhelds replace the original EcoSense pH100, DO200 and EC300 handhelds. The new EcoSense line with added features and benefits provides accurate data in an affordable format utilising YSI sensor technology.
The pH100A measures pH, mV and temperature featuring an easy- to-use interface, one-hand operation and IP-67 waterproof case. Additional features include; internal buffer recognition (US or NIST buffer sets), a low battery indicator with a 1000 hour battery life, a 50 data set memory and 1- and 4-meter cable options.
The DO200A measures dissolved oxygen (% saturation and mg/L), BOD and temperature featuring an easy-to-use interface, one-hand operation and IP-67 waterproof case. Additional features include:a low battery indicator with a 500 hour battery life, manual salinity and pressure compensation, screw on cap membranes with low stirring and fast response and 4- and 10-meter cable options.
The EC300A measures conductivity, specific conductance, salinity, TDS (total dissolved solids) and temperature featuring an easy-to-use interface, one-hand operation and IP-67 waterproof case. Additional features include; as with the DO200A there are 4- and 10-meter cable options, a low battery indicator with a 500 hour battery life and a super-stable, four-electrode conductivity cell designed for field durability.

A specially designed fixture, the “V” Block, automatically holds in correct alignment any standard 150 mL beaker or calibration standard. The spring automatically pushes the bottle up into the “V” position. It is easily removed (by unscrewing two 6/32 screws) for small vial or flow-thru cell attachment.
The Model PC-2200 Particle Counter provides all of the facilities needed for rapid inspection of bottled and flowing liquids. Small particulate matter is automatically quantified by a scanning laser beam and the results presented on a digital display. A minimum size selector is provided for this quantification measurement and is normally set to 1µm.
Spectrex Corporation also offers a portable version of the Particle Counter, the PC-2300. Reader Reply Card No. 63
Analysing Marine Life from Reflection and Fluorescence to Upwelling or Downwelling
Ocean Optics (Netherlands) offers an extensive range of products to analyse marine life. Ocean Optics offers a large range of spectrometers, light sources, excitation sources and accessories to measure the reflection and fluorescence to analyse soft corals and other marine life. We also offer systems to measure the relationship between radiation that is directed upwards from the earth surface (upwelling) and radiation that is directed towards the earth surface (downwelling) to give (spectral) information about vegetation, forest canopies, sea beds and more.
For example, Ocean Optics spectrometers have been used to measure the effects of strip mining on coastal erosion, sea grass growth and coral reef
health. The team of researchers focussed on the relationship between above-water reflectance and turbidity profiles. The latter relates to fluxes in the presence of metals and other various pollutants and thus to sea growth and coral reef health.
