Ion Science refocuses on MiniPID sensor

Well-proven Plug and Play miniature photoionisation sensor to benefit from several enhancements aimed at further improving performance and efficiency

Ion Science: Further underlining its position at the forefront of gas detection monitoring instrumentation for occupational health and the environment, Ion Science (www.ionscience.com) is refocusing on its range of MiniPID (miniature photoionisation detection) sensors during 2016. As part of this latest R&D initiative, the company is set to introduce a series of enhancements designed to further strengthen the plug and play sensor’s performance and efficiency.

Ion Science’s well-proven, ATEX accredited MiniPID is a simple plug and play sensor that has been specially developed to deliver a dynamic and dependable response to thousands of VOCs (volatile organic compounds).

The MiniPID is widely used across a range of global occupational health and environmental monitoring applications, including personnel safety, industrial hygiene, site soil and air sampling, fugitive emissions and VOC spills, law enforcement and emergency response.

Available with a 12-month warranty but with an impressive five-year life expectancy (excluding replaceable lamp and pellet), the complete MiniPID series boasts Ion Science’s patented Fence Electrode Technology for industry-leading humidity resistance performance. In addition, the sensor’s clever anti-contamination design protects it from moisture, dust and aerosol ingress.

Specially developed for both diffusive and in-line pumped sampling, Ion Science’s MiniPID delivers an exceptional response and clear down time.

With highly efficient lamps that offer excellent brightness and stability, the MiniPID is able to reliably detect less volatile and readily sensed compounds over an extended period of time.

It also features a removable, pneumatically sealed sensing pellet and series four / A1 format.

There are currently several models in the Ion Science MiniPID range. The 0.1 to 6000ppm (parts per million) sensor is configured for a dynamic, accurate and repeatable response to VOCs at elevated concentrations. The ppb (parts per billion) MiniPID offers a minimum detection limit of 1ppb and is designed to deliver a very low background current for optimum low end sensitivity.

The 10.0 eV MiniPID, which offers a range of 5ppb to 100ppm, is the latest addition to the three pin family and is used for selectivity of VOCs with lower ionisation potentials. A common application for this sensor is the determination of ambient levels of aromatic compounds.

Ion Science also offers an 11.7 eV MiniPID. With a range of 0.1 to 100ppm (isobutylene equivalent), the 11.7 eV lamp extends the amount of VOCs detected to include chlorocarbons, CFC, formaldehyde and chlorine.

Optional accessories available with the MiniPID range are PPB and 10.0 eV pellets, lamp cleaning kit, pellet removal tongs and 10.6 eV lamp and HPPM stack. Ion Science’s Managing Director, Duncan Johns, comments: “Our MiniPID has been extremely successful since its launch in 2007. However, as a technological leader in the gas detection instrumentation market, we felt it was time to refocus on this key sensor. As a result, we are currently investing in several enhancements that we believe will further improve its sensitivity and reliability.”
