  • Peracetic acid (PAA) as a sterilizer

    Peracetic acid (PAA) has been used since the early 1950's as a disinfectant in the food industry.  Exposure level guidelines are important to follow when using any type of gas when cleaning for personnel safety.  Below is an article on the Peracetic acid exposure levels that should be followed.

    Monitoring equipment for Peracetic Acid can be found on our website.

    Peracetic Acid Occupational Exposure Levels

    Peracetic acid (PAA) is gaining wide acceptance as a disinfectant and sterilant in many industries including healthcare, food processing (aseptic packaging, bottling, dairy and meat) and water treatment. PAA acid is a relatively simple chemical formed as an equilibrium component in a mixture of hydrogen peroxide and acetic acid; with excellent disinfection properties and additionally PAA is environmentally benign since it rapidly breaks down to harmless product (acetic acid and water).

    Any broad spectrum disinfectant or sterilant is potentially hazardous to people exposed to it and the widespread use of PAA has meant that there is the potential for workplace exposure. While employers have a duty to ensure a safe workplace [OSH Act (1970) sec. 5], it has been difficult to determine what level of PAA exposure is safe since there is no OSHA permissible exposure limit for PAA and little other guidance.

    Guidance is now available: The EPA published acute exposure guidelines for PAA in 2010, available at http://www.epa.gov/oppt/aegl/pubs/results80.htm. In addition, the ACGIH has recently published a notice of intended change to introduce a short term exposure limit (STEL) of 0.2 ppm for PAA to The notice is available from the ACGIH website at http://www.acgih.org/store/ProductDetail.cfm?id=2199 and marks a significant improvement in the hazard assessment information available to employers using PAA.

    Knowing the exposure limit is only helpful if the actual exposure can be measured; and the ChemDAQ offers continuous monitors for PAA, designed to operate with sufficient resolution to provide protection at these low levels.

  • Particulate Matter (PM) sensor

    A new PM (Particulate Matter) sensor will be released in September and is designed to simultaneously measure PM2.5 and PM10 for indoor and outdoor use. This portable particulate monitor will display real-time measurements of particulate matter. (See picture of the display below)

    Particulate Meter readout

    The PM sensor will need to be used with the portable base Series 200, Series 300, or Series 500 that gives the digital readout of the current particulate matter measurement.  Like the other Aeroqual sensors, the PM sensor head can be swapped around and the same base can be used with up to 30 different gas sensors.

    Particulate Matter Sensor

    From the manufacturer Aeroqual: "Field tests have shown the portable particulate monitor provides useful data when compared to traditional ‘reference’ methods. This data will be made available on commercial release of the product."

    GasSensing is excited to offer this new PM sensor in September as we feel it will be a great addition to the Aeroqual sensor line.  In addition to being able to purchase this sensor from GasSensing, we will be offering the PM10/PM2.5 as a rental sensor with the Series 500.

  • Wireless Gas Monitoring

    Wireless gas monitoring

    Recently Gas-Sensing introduced a new accessory making it possible to connect gas monitors to the internet. We call this accessory the Wireless Monitoring and Data Logging Kit. This has sparked a lot of interest and we have had excellent feedback from our customers who have purchased and are using this kit.

    How it works

    The Wireless Monitoring and Data Logging Kit works by wiring a current or voltage sensor to the analog outputs, which correspond with the gas concentration on a fixed gas monitor. The current or voltage sensor communicates with a gateway which is connected to the internet, and finally to view and collect the data in real time, you simply open up the online portal with the credentials we provide you.

    Wireless gas monitoring How the wireless monitoring and data logging kit works

    Wireless Sensor                             Wireless Gateway                              Online Portal

    This essentially makes any fixed mount gas monitor we offer wireless and IoT enabled (Internet of Things).

    Advantages to connecting a gas monitor to the internet:

    • Knowledge of gas concentrations anytime, from anywhere by simply opening our app on a smartphone.
    • Free email and SMS text message alerts for alarming situations.
    • 24/7 data logging to view trends over a given amount of time.
    • No monthly fees.

    This accessory will be wired and mounted on your gas monitor before shipment, making this as user friendly as possible.

    Here is one of the success stories we have had since launching the Wireless Monitoring and Data Logging Kit.

    Brandon works for a University and sterilizes laboratories with high concentrations of Hydrogen Peroxide. He would typically treat 3 rooms simultaneously, and all three rooms were connected to a hallway.

    Before contacting Gas Sensing he was unsure of the Hydrogen Peroxide levels achieved  during a treatment inside of the rooms. He also had to sit in the hallway with a handheld monitor during the entire treatment  (4-5 Hours).

    So we provided a simple solution.

    Wireless gas monitoring Wireless monitoring and data logging kit for Hydrogen Peroxide

    We provided him with 3) 0-1000 PPM Hydrogen Peroxide sensors for the rooms being treated, and 1) 0-10 PPM Hydrogen Peroxide Sensor for the hallway to detect any possible leaks.

    This was using the B12 2 Wire Transmitter from ATI, with the remote monitoring and data logging accessory attached.

    This way Brandon could open up the online portal to see his hydrogen peroxide concentrations in real time, and set notifications when specific conditions are met.

    online portal Online portal to view gas concentrations remotely

    This is what Brandon had to say after using these products:

    “ This is the perfect set-up for any facility or company that has to do large scale decontamination projects. It eliminates having to run cables under doors then going back and trying to keep the VHP from leaking out. I’m really impressed because it made my life and job 100x easier. Now I don’t have to sit in the hallway for hours, I can just set the monitor outside and have it send me a notification if it senses anything above 1 PPM! “
