UK FOCUS v Range of OEM gas sensors


delivers superior air quality monitoring solutions for improved public health


The impact of air quality on health and wellbeing has been rising on the agenda of governments and private sectors. Sick Building Syndrome has been a recognised cause of illness amongst office workers for almost four decades, caused by poor indoor air quality. WHO estimates that poor urban air quality accounts for up to 7 million deaths each year. In 2014 alone, it was responsible for approximately 1 in 8 deaths globally. ION Science is tackling this health crisis with its range of high-quality gas sensors and monitors, designed to


help control and improve air quality for health, wellbeing and the environment.


As an industry leader and OEM producer of gas sensors, detectors and monitors of volatile organic compound (VOC) using photoionisation detection (PID), ION Science is dedicated to improving air quality, health, and reducing harmful emissions. As a key part of their work, they have developed a range of sensitive and widely applicable sensors capable of detecting even the smallest levels of VOCs or other harmful compounds.


In 2020, COVID-19 had one unintended outcome; it caused a global dip in carbon emissions and resulted in much-improved air quality, particularly in urban areas. As people have seen the reality and health benefits of having cleaner air, both inside and outside, the focus to make this a permanent fixture has taken on greater importance. Using gas sensors is a realistic and achievable way to monitor and improve air quality in all environments, workplaces, homes, and outdoor spaces.


Ion Science is dedicated to improving air quality at every level, and they manufacture a range of sensors to make this possible. With various levels of sensitivity, size and application, it’s possible to install gas and VOC sensors almost anywhere. Sensors can be installed individually or incorporated into other machines and sites, for fixed or portable use.


The MiniPID 2 range is able to deliver high sensitivity VOC readings in even the harshest conditions. Able to withstand humidity between 0-99% temperatures of -40 to +65 °C, and with an anti- contamination design, the MiniPID range offers 10,000 hours of lamp life, ideal for long term monitoring in any location. Options include the MiniPID 2, PPM, PPM WR, PPB and PPB WR. For whatever sensitivity you need to be detecting, whether it’s in ppm or ppb, over a wide or narrow dynamic range , the MiniPID range is able to help monitor and control air quality indoors and out.


For the highest level of air quality control and monitoring, Ion Science offers the High Sensitivity (MiniPID 2 HS) VOC Gas Sensor. Fifteen times more sensitive than other leading market products, the HS VOC Gas Sensor can detect sub ppb VOC levels. This makes it particularly suitable for use indoor air quality measurement, where early detection of rising VOCs levels can allow action to be taken before dangerous levels are reached.


Ion Science’s PID sensor offers world leading humidity resistance and long-term stability. For individuals working in high-risk fields such as nuclear, oil and gas, mining or other dangerous environments, ION Science offers three energy sensors, 11.7, 10.6 and 10.0 eV VOC Gas Sensors. The 11.7 sensor detects the most chemicals, but to detect VOCs with a lower ionisation energy, a lower energy level sensor often provides a better solution, as it will detect common aromatics such as benzene.

New heating/chilling HPLC column temperature controller


email: For More Info, email: email:


Torrey Pines Scientific, Inc announces its new EchoTherm™ Model CO50 Programmable HPLC Column Chiller/Heater.


The unit has a temperature range from 4.0°C to 100.0°C readable and settable to 0.1°C. The PID control software regulates temperatures to ±0.2°C, even at ambient. The CO50 has a Stable Temperature LED that illuminates when the target temperature is stable to within ±0.2°C.


The Peltier-based CO50 has 5-program memory of 10 steps per program and the ability to repeat any program from 1 to 99 times automatically. It is ideal for chiral and biomedical chromatography


where below ambient temperatures help preserve bioactivity. It can be used for stabilising column temperatures from day to day at or near room temperatures for repeatable results. The CO50 holds columns up to 30cm long by ¼” or 3/8” diameter in mounting clips provided. Larger diameter columns can be used by removing the column clips that hold the smaller columns.


The CO50 features RS232 I/O port for controlling the unit by a chromatograph, for programming gradients, and for data collection. Also included are an injection counter, 30-day timer with user settable Auto-Off, and chamber drain for spills.


The unit comes with a bench top universal power supply for use anywhere in the world, 3-wire AC line cord for the country of use, twelve month warranty and instruction manual. The Model CO50 is UL, CSA, and CE compliant.

The third and final session was on Global Mercury Monitoring Mercury Monitoring: A Global Challenge – Dr Lesley Sloss, IEA Clean coal Centre Global mercury monitoring requirements – David Graham, Uniper


Monitoring of mercury emissions under the Waste Incineration BREF – continuous or periodic – Ben Freeman, Environment Agency


Mercury emission monitoring: EN 13211 vs. Sorbent Traps (CEN/TS 17286) – Johannes Pfingsten, VDZ Service


Mercury Sampling in the USA – Shawn Wood, Ohio Lumex


Our special thanks goes out to David Graham for chairing the Low emission conference, Dr Roger Brown for chairing the Biogenic Carbon Measurement conference and to Dr Lesley Sloss for Chairing the Global Mercury monitoring conference. Extended thanks to all the speakers involved. If you missed out on the conference or would like to listen again you can do so at www.ilmexhibitions.com/ aqeshow/emissions-monitoring-conference/


What is coming up for the rest of the year for the STA?


On the 11th November we held our third and final general meeting for the year, the 24th November was our EN14181 task group and on the 6th of December we will be holding the HCL task group followed in the afternoon by the Low Particulate Monitoring Task group. I look forward to reporting back in the next STA focus column on the outcome of these meetings and remember it’s your STA, the STA meetings and task groups are available for all STA members to attend and contribute. If you are an existing STA member and not already involved in the valuable work the STA does or if you are interested in becoming a member, please email info@s-t-a.org and one of the team will contact you.


The STA Focus


Thanks to all those that attended the STA conference at the Air Quality Emission (AQE) show which was held virtually on the 13th and 14th of October 2021. I hope you agree it was a great conference with excellent speakers from the UK, Europe and the USA. For those that missed it, the STA’s conference focused on three key areas this year.


Day one discussed low emissions, where we addressed the positive problem of ever lowering emission limit values, the talks included:


Measurement uncertainty – performance of methods at low concentration - Rod Robinson, NPL.


Quality assurance issues associated with continuous emissions monitoring of gaseous pollutants at low concentration levels – David Graham Uniper
