MCERTS key to emissions monitors’ rental popularity

  • PDF

Quantitech, the Milton Keynes based environmental instrumentation specialist, has reported a surge in demand for its rentable emissions analysers. The company’s Dominic Duggan says: “This is undoubtedly for two reasons; first and foremost, the two main analysers are MCERTS approved and secondly, they are both transportable and simple to carry from one site to the next.”

Air Monitors launches nanoparticle detector

  • PDF

Traditional methods for measuring airborne particulate matter measure particle mass per unit air volume, usually with an upper size limit of x microns (PMx etc.). However, from a human health perspective, the particles of most interest are those that penetrate deep into the lungs. For this reason, Air Monitors has launched the Naneos Partector nanoparticle detector in the UK.

Ion Science Tiger VOC detector helps BAMRitchies Limited to stay on track

  • PDF

Handheld PID used for nightly monitoring of volatile organic compounds (VOCs) during on-site headspace testing of contaminated soil samples on railway contracts.

Award-winning geotechnical company, BAMRitchies Limited, is using an Ion Science (www.ionscience.com) handheld Tiger photoionisation detector (PID) for nightly monitoring of volatile organic compound (VOCs) concentrations during on-site headspace testing of contaminated soil samples on railway contracts.

EatBy App launches on World Environment Day

  • PDF

A major new money saving and environmentally beneficial smart kitchen app is due to be launched on the 2015 World Environment Day, Friday 5th of June. The hotly anticipated EatBy App has been tipped to become the must have app of 2015 as it promises to save it's users up to £700 every year and help reduce food waste.

Quantitech’s FID claim upheld

  • PDF

altIn a recent press release Quantitech Limited announced that the SICK 3006 is the only portable FID with MCERTS approval for using either hydrogen or hydrogen/helium fuel gas. This claim was challenged, but Sira Certification has confirmed that the 3006 passed the MCERTS performance requirements for both gas options.

So, why is that important? Quantitech Director Dominic Duggan explains: “The hydrogen/helium fuel gas mixture is at least three times the cost of hydrogen gas, so one might assume that all FIDs would run on hydrogen. However, some FID manufacturers are unable to achieve the MCERTS performance requirements whilst running on hydrogen and have to resort to the more expensive mixture.

Portability key to success of oil in water analyser

  • PDF

Quantitech first launched the InfraCal 2, a portable oil in water analyser, in 2013 and the company’s Dr Andrew Hobson says: “There has been a heavy demand for this instrument in the oil sector because of the new functionality that now comes as standard.The InfraCal2 can now be operated from an internal battery and also provides lower detection limits.

However, the original InfraCal was not able to store multiple calibrations or to log readings, so the latest instrument can be more independent, making it better suited to remote operation. We are therefore hoping that it will also become popular in a wider range of other manufacturing and processing industries, including wastewater and fracking.”

Successful trial for new remote Phosphate monitor

  • PDF

Researchers at the UK’s Centre for Ecology & Hydrology (CEH) have conducted trials on the river Thames to evaluate a new remote phosphate monitoring technology (Cycle-P)as part of a high-frequency (hourly resolution) monitoring programme that is studying river nutrient concentrations and how they are affected by algal abundance. The monitoring system ran continuously over the summer of 2014,measuring total reactive phosphate levels in the river, day and night, seven days a week. These results have now been compared with manually collected samples that were analysed in a laboratory with the traditional Murphy and Riley spectrophotometric method on unfiltered samples, and Dr Mike Bowes, senior nutrient hydrochemist at CEH, says: “The Cycle-P is working really well; the system operated independently for long periods and produced results that tracked our lab samples closely.”

Most water quality parameters are relatively simple to measure with low-power accurate sensors. However, the measurement of phosphate necessitates colorimetric analysis and this presents a significant challenge in remote locations with difficult access or where mains power is not available. The Cycle PO4 from OTT Hydrometry (known as the Cycle-P) is therefore gathering considerable interest because it is battery powered and able to operate unattended in the field,running over 1,000 tests before a field service is necessary to change the reagents.

New trace chemical analyser for onsite analysis

  • PDF

Quantitech (Milton Keynes) has announced the launch of theFROG-4000™, a rugged, portable instrument capable of analysing trace levels of individual volatile organic compounds (VOCs) in air, soil and water. “With this technology, operators will be able to conduct fast on-site analysis in a range of environmental, health and safety applications,”says Quantitech’s Dr Andrew Hobson. “The ability to analyse VOCs quickly, on-site, is a major benefit; partly, because samples containing volatiles are notoriously difficult to transport, but also because many applications require instant data.

For example, land remediation companies need to know which soil is contaminated so that they can either store or treat it, and they need to know if treatment was successful. Theymay also need to test liquid effluent against a discharge permit.

Certification boosts demand for FTIR multigas analyser

  • PDF

Quantitech has experienced a surge in demand for the Gasmet portable FTIR emissions analyser, the DX4000. “We believe that this instrument is now the only portable FTIR with MCERTS certification, and this is driving demand for both instrument rental and sales,” says Dominic Duggan.

The Gasmet DX4000 portable FTIR gas analyser is typically used in stack emissions monitoring, comparison measurements, catalytic process control and other applications where multiple gas compounds need to be accurately monitored in a hot and humid sample gas. The corrosion resistant sample cell is heated to 180 °C, which ensures that the sample stays in the gaseous phase even with high concentrations of moisture or corrosive gases.
