Protecting the environment and your reputation with organic carbon analysis

21 June, 2010 by Jimmy Britz, Analysis Product Manager, Endress+Hauser Australia

Monitoring and controlling the amount of organic matter in our streams and waterways is critical for environmental protection. Total organic carbon (TOC) is the amount of carbon present in an organic compound and measuring it provides a fast and convenient way to determine water quality. This article looks at the different methods now available for analysing TOC.

ABB Endura AZ20 combustion gas analyser

28 April, 2010 by

Manufactured using a ceramic-to-steel bonding process, the Endura AZ20 combustion gas analyser offers improved resistance to thermal stresses and shocks compared to a conventional brazed design. This enables it to be used in a wider range of applications subject to sudden variations in process temperature, as well as offering a gas tight bond throughout its operating temperature range.

Aurora natural gas moisture analyser

28 April, 2010

The Aurora analyser uses tuneable diode laser absorption spectroscopy (TDLAS) to quickly measure moisture in natural gas.

Endress+Hauser TOCII CA72 total organic carbon analyser

22 January, 2010

The TOCII CA72 total organic carbon analyser is a high-temperature TOC analyser that uses an exchangeable combustion unit to reduce maintenance downtime by 80% and a rotating shaft filter to eliminate blockages by particles larger than 200 microns.

Rain and spill detectors

26 October, 2009 by

Amalgamated Instrument Co has announced a flood/liquid detection and alarm system and a rain/precipitation detection and alarm system. The systems consist of a common detection and alarm module and specialised sensors for each function.

Energy monitoring system

29 September, 2009 by

OneTemp has released the Hobo U30-ETH remote monitoring system, an industrial-grade energy monitoring system that provides real-time, remote access to energy and environmental data over any ethernet network.

Airborne particle counter

29 September, 2009 by

The Lighthouse Solair 1001+ airborne particle counter offers a sensitivity of 0.1 µm with a flow rate of 0.01 CFM (0.283 LPM) and a wide dynamic range up to 20 µm.

Turbidity systems

25 September, 2009 by

The CUE21 is a compact, online turbidity system that can function at low flow rates. The use of an infrared light source enables measurements that are unaffected by the colour of the water, with an optional white light version which provides measurements according to the standard method described in US EPA 180.1.

Wind speed and direction transducers

25 August, 2009 by

A wide range of wind monitoring transducers by Mierij Meteo is now available. The range includes models suitable for most applications where wind speed and direction need to be monitored.

Breathe easy

10 July, 2009 by Darrell Leetham, Thermo Fisher Scientific

For many organisations today, one aspect of the manufacturing process that needs to be monitored and controlled, for both efficiency and environmental benefit, is gaseous emissions.

Dairy reduces effluent and increases yield with TOC analysis

04 June, 2009

The Murray Goulburn dairy factory in Maffra, Victoria, processes four million litres of raw milk per year into intermediate products including butter, cream, anhydrous milk fat and milk powders. The installation of a total organic carbon (TOC) analyser has paid back its investment several times over by limiting COD discharge levels outside the trade waste agreement, thus minimising additional charges previously incurred.

Reagent-free inline ammonium analyser

11 May, 2009 by

The ISEmax CAS40 provides in situ measurement of ammonium and nitrate. This robust inline probe can significantly reduce the energy costs associated with aeration systems in nitrification and denitrification processes in wastewater treatment.

Oil-in-water measurement

01 April, 2009 by

Enviro-Flu-HC is a new generation of highly sensitive submersible sensors for oil-in-water measurement. The UV fluorescence principle used for detection is claimed to be more sensitive than other existing detection principles, such as infrared scattering.

Inline water quality monitoring in distribution pipelines

01 April, 2009 by

The Intellisonde multi-parameter monitoring system is a measuring device designed for direct insertion into potable water pipeline distribution networks, providing benefits including: continuous water quality monitoring within the distribution system; integration into a water utility data collection system such as SCADA; providing real-time and historical data — both alphanumeric and graphical; assistance with compliance and regulatory requirements; analysis of the distribution network; and minimising risk of contamination posed by bursts and repairs.

Product recall of faulty CO detector

25 August, 2008

The Department of Mining Safety and Health has issued a product recall of Industrial Scientific’s 4CF carbon monoxide sensors, after finding some makes could suddenly stop detecting the gas.
