Ecological bio-decontamination with vaporized hydrogen peroxide

I den här tekniska e-boken lär du dig de grundläggande konverteringsformlerna för förångad väteperoxid. Med hjälp av de här formlerna kan du göra dina egna beräkningar.

Vaporized Hydrogen Peroxide (vH₂O₂), a common disinfection agent in life science industries, is used to bio-decontaminate numerous applications including: incubators, isolators, cleanrooms, and process lines.

In this webinar we compare relative humidity sensors, relative humidity sensors with a catalytic layer, and the combination of these two sensors in a single probe – Vaisala’s PEROXCAP® sensor.

A unique feature of the HPP270 series probes is the ability to evaluate the sensors’ performance through its “Sensor Vitality” value. This value is like a health check for the sensor.

In this video, Vaisala Application Engineer Nevon Mansour demonstrates how to connect and configure the Vaisala HPP272 probe, which is used for vaporized hydrogen peroxide bio-decontamination applications.

Watch this recorded webinar to understand the relationship between the key parameters in bio-decontamination with vaporized hydrogen peroxide; specifically relative saturation and relative humidity.

In this webinar, we discuss the methods for calculating different humidity and vaporized hydrogen peroxide variables, such as: relative saturation, parts per million, and mixture dew point temperature.

All questions from the webinar "Humidity measurement in H₂O₂ bio-decontamination – relative saturation as the key" are answered in this blog.

Lear about critical process parameters that ensure the efficacy of bio-decontamination processes, including: ppm (H₂O₂), Relative Humidity, Relative Saturation, and Temperature.

Using the HPP270 probes has allowed TKSAGE to improve the adaptability and stability of their bio-decontamination solutions by increasing the sensitivity and accuracy of vH₂O₂ measurement and solving condensation control issues.

“The HPP270 was the only probe we found that offered all these parameters in one unit. And it was the relative saturation value that was crucial to ensuring the generator could automatically and effectively adjust cycles.”

Iacobus often performs bio-decontamination in hospitals in environments like patient rooms and operating suites. Because hospital beds are always in demand, the duration of room bio-decontamination is crucial.

For several years, STERIS has used a trusted sensing technology from Vaisala. In 2018, STERIS became interested in a new solution from Vaisala: the HPP270-series hydrogen peroxide vapor probe.

Vaporized H₂O₂ is becoming a favored bio-decontaminant due to its low toxicity and high efficacy in diverse applications. Because hydrogen peroxide decomposes into water and oxygen, it is more environmentally friendly and safer for operators than traditional bio-decontamination chemicals, such as formaldehyde or chlorine dioxide.

The Cleamix bio-decontamination units are portable, highly efficient hydrogen peroxide vapor generators. The generators use Vaisala’s HPP270 series probes to automatically control vapor output during bio-decontamination.
