How to protect your staff from SARS-CoV-2, its variants, and other microbiological hazards


Portable quadrupole analyser for environmental field studies


The Hiden pQA portable gas analyser is a versatile mass spectrometer and offered with a range of interchangeable sampling inlets to suit a broad application range. MIMS inlets are offered for analysis of dissolved species in ground water, fermentation cultures, soil samples, and general applications where analysis of dissolved species in liquid sample is required.


The system is suited to gas analysis applications, where sample volume is small, and for environmental applications where detection of low concentration levels is required. The pQA system has a mass range of 200 amu and sub ppb detection levels. Extended mass range to 300amu is optional. The system is supplied in a Pelican® case and can be powered by a 12 V supply for field use, battery and/or solar powered, or a 220 V supply for laboratory use.


Sampling inlet systems are offered for a broad application range including: Direct membrane inlet probe for immersion and/or insertion in liquid or sludge sample, soil core sampling for example; Recirculating probe for analysis of sample with continuous flow, extracted sea or estuary water for example; Flow through probe, low flow design for denitrification studies.


The system includes: Quadrupole mass spectrometer system from the RGA series with mass range options 200 amu; Mass spectrometer analyser manifold and UHV pump set with a manually valved dissolved species probe with silicone rubber membrane; Ion Gauge and interlocks to provide protection for the mass spectrometer in case of over pressure; fast acting shut off valve between the dissolved species probe and mass spectrometer manifold to protect the mass spectrometer in case of membrane failure - the valve is interlocked with the integral UHV pressure gauge; supplied in a ruggedised Pelican case for usability in the field; can be powered by a 12 V supply, from a vehicle power outlet, for example as well as a standard power outlet for laboratory use; total weight is less than 40 kg.

The return of office workers presents a new challenge to businesses seeking to protect their staff and visitors from the risks posed by SARS-CoV-2, its variants, and other microbiological hazards. “It’s not as simple as turning up the ventilation, or installing new ventilation,” claims indoor air quality expert Keith Esdon. “Viruses are spread by infected, possibly asymptomatic, people, so it will be necessary to remove infectious particles from expired air when people meet, and that is why we developed Meeting-Air™, a low-cost but high-specification air filtration device that sits in the middle of a meeting room table, drawing air from meeting participants and removing potentially hazardous particles.”


Coronaviruses, and other airborne pathogens, spread when people either inhale infectious particles or touch infected surfaces and then touch their face. Contact transmission can be reduced by frequent hand washing and by treating surfaces with wipes or fogging with disinfectant. Airborne transmission can be reduced by ventilation, but even if these measures are in place, an infected person can quickly contaminate the air in a meeting room.


Following the Covid pandemic it is likely that office staff with cold or flu-like symptoms will stay away from work, so the main risk will be from asymptomatic people. Instead of coughing larger particles, it is likely that these infectious individuals will unknowingly exhale small viral aerosols. Studies of cough aerosols have shown striking similarities in aerosol size distributions, with a predominance of pathogens in small particles (<5 µm), which settle less readily and are easily inhaled.


Meeting-Air has a 360-degree inlet at the base which draws air through 2.8m2 of medical grade (H14) pleated HEPA filter which removes all particles over 0.3µm. There are three speed settings – the two lower speeds are designed to minimise disturbance during a meeting, and a third ‘boost’ speed (up to 250m3/hour) is available for removing excess aerosols before or after a meeting.


Summarising, Keith says: “The Covid pandemic has highlighted the need for microbiological risks to be included in Health & Safety policies, and whilst new disinfection procedures, including hand washing, decontamination routines, ventilation and social distancing will all play important roles; meeting rooms and offices represent an ideal opportunity for disease transmission, unless technology such as Meeting-Air™ is deployed.

Quality Monitoring…and much more When Enviro Technology (ET) was started in 1983, the product range was small and the philosophy simple, “to supply innovative air quality monitoring analysers and offer the very best levels of service and support.” Fast-forward 38 years to 2021 and the Company’s founding philosophy remains unchanged. The product range has expanded and taken the business into many new directions. These include CEMS, atmospheric chemistry and aerosol research, greenhouse gas and stable isotope measurements, vehicle emissions measurements and mobile laboratories.


Enviro Technology’s Managing Director, Duncan Mounsor comments “our air quality monitoring stations and MCERTS approved ambient gas and particulate analysers for NOx, SO2

, CO, O3 , PM10 and PM2.5 are used primarily on the UK’s national networks and by many local authorities, and it is


this business that we are most well-known for. However, over the last ten years, our carefully chosen range of next generation monitoring technology has brought us to the attention of many of the UK’s leading research universities and institutes who are using our instruments for all manner of leading research into; agricultural emissions, carbon and greenhouse gas cycling, atmospheric remote sensing and particulate matter composition and characterisation”.


Duncan concludes “whilst very much still specialising in air quality monitoring, our instrument expertise and a continual awareness of customer wants and needs over the last four decades has moved us into many exciting new sectors, all with one thing in common: the need for high quality instruments and superior service and support. And these are all watch-words for ET”.


At the Air Quality and Emissions Show (AQE) Virtual Event on the 13th and 14th of October, we are launching a brand-new range of CEMS and ambient analysers from the world leading analyser manufacture, Teledyne-API. The new N-Series builds upon, and takes over from the T-Series, which have enjoyed sales of tens of thousands of units over the last decade and can be found on every continent. N-Series instruments combine sophisticated CAN BUS technology with maintenance friendly design, guaranteeing simple operation and integration. Using the latest electronics and the powerful, innovative NumaView on-board software, N-Series analysers are both ‘future-proof’ and packed with user benefits.


And with the IPPC recently issuing the Code Red warning re: climate change, we are also showcasing some of our wide range of Greenhouse Gas Analysers from ABB Los Gatos Research for the measurement of CH4


, CO2
