Reporting Ultra Low Mercury Concentrations in Environmental Samples
The Millennium Merlin (liquid) and Sir Galahad (gaseous) from PS Analytical (UK) provide industry leading performance for fund- amental sensitivity when measuring the mercury concentration in a wide variety of matrices.
The Millennium Merlin instrument is capable of measuring concentrations of mercury down to 0.1 ng/l (sub ppt) levels in liquid samples and the Sir Galahad has a detection limit below 0.1 ng/m3
range without dilution. . However, it is important to realise that the
instruments also have a wide linear dynamic range and are capable of accurate and reliable measurement of mercury over 7 orders of magnitude. This allows liquid samples to be analysed in the mg/l or ppm range and gaseous samples up to the µg/m3
A further benefit in using atomic fluorescence as the detection mode for mercury analysis is that it is highly specific
for mercury detection and there are no known interferences in this analytical technique. The systems are easy to use and have proven over more than 25 years that they are rugged and reliable in operation – allowing a mercury result to be provided in under 2 minutes.
As well as providing laboratory instrumentation, P S Analytical offer both liquid and gaseous system for continuous on-line operation to meet accepted international safety standards. Many of these systems have been running unattended on a 24/7 basis throughout the world.
Atomic fluorescence is widely accepted by legislative bodies as the technique of choice for mercury analysis in a range of matrices from oil and gas to potable water.

New Portable Fluorescent Leak Detector Spectronics Corporation (USA) has unveiled the new Spectroline®
OPX-3000
OPTIMAX™ 3000 —the world’s most powerful, portable fluorescent leak detection flashlight. With its focused beam, the OPTIMAX™ 3000 makes it easier than ever for technicians to pinpoint all refrigerant leaks — even those elusive leaks that are missed by other lamps and by other methods of leak detection. And there are no cords that can become snagged on components of the industrial equipment.

The OPTIMAX™ 3000 uses breakthrough super-hi-flux LED technology to deliver 15 times brighter leak detection light than regular LED lamps. Its power equals that of 150-watt lamps that must be plugged into an AC power source, and it has an inspection range of up to 20 feet (6.1 m) or more. Powered by a rechargeable NiMH battery, the unit has a 50,000-hour LED life.
Sierra Positions Company to Meet Global Environmental Challenges Sierra Instruments has launched a completely redesigned website that
features a new Sierra logo. The new landing page video also introduces “Think Ahead”, their new global campaign that focuses on clean energy solutions and provides a PDF download of their new 40-page Sierra Clean Energy Guide. The guide details how Sierra has partnered with customers from all over the world to develop sustainable solutions to some of today’s most pressing environmental problems.
From high performance flow measurement tools that help create biofuel from solid wastes to unlocking the
carbon history in Antarctic ice to determine how much CO2 the ocean can digest, the Sierra Clean Energy Guide details a broad range of problem/solution scenarios.
“The environmental and economic challenges we face right now are huge,” says Matthew J. Olin, President of Sierra, “and we’re doing everything we can to support the visionaries that are passionately pursuing a more sustainable future. Our new feature-rich website represents a big leap forward in our ability to meet customer needs. Our new Sierra Clean Energy Guide introduces some of our most innovative partners and the unique solutions we have developed by “Thinking Ahead”
...together.
The new website was developed to make it easier for customers to identify and select the right flow control and monitoring instrument they need for their applications and get product information and quotes faster. Access to sales and technical support has been enhanced to rapidly put customers in touch with one of 150 branches in more than 50 countries. New quick links make it easier for visitors to download Sierra’s technical literature, white papers, or view educational videos.
