Accurate detection of Glutaraldehyde


Source: PPM Technology

The Glutaraldemeter 3 by PPM Technology is an easy-to-use, portable instrument that employs an electrochemical sensor to indicate levels of glutaraldehyde vapor in air. The instrument provides a rapid direct read-out of vapor levels on an LCD display, making it a useful screening tool to complement existing routine chemical glutaraldehyde monitoring techniques.

  •  User friendly and easy to use
  • Auto zero function to prevent sensor creep
  • Peak hold function and time-to-peak analysis
  • Ten reading memory
  • Automated calibration procedure

By using the time-to-peak function the user can ''spot'' false readings and improve the selectivity of the instrument. This is because common chemicals such as ethanol, propanol and butanol have a time-to-peak on the sensor which is much quicker than that of glutaraldehyde.

Advantages: Uses:
  • Easy to use - minimal operator training required
  • Rapid response time
  • Real time readings allow immediate response to results
  • Reliable electrochemical sensor
  • Does not require inconvenient ancillary sampling equipment or readers
  • Simple in-field calibration
  • Connectivity to AMS-2 or PC for continuous monitoring
  • Medicine
  • Dentistry
  • Pharmaceutical
  • Vetinary Medicine
  • Paper manufacture
  • Leather & Textile treatment
  • X-Ray processing
  • Microbiology
  • Histopathology
  • Endoscopy

Glutaraldehyde is a colourless liquid with a pungent odor mostly used to sterilize medical and dental equipment or as an embalming fluid.

Because glutaraldehyde is a liquid at room temperature it can affect the health of users as a vapour and through physical contact with the skin. Glutaraldehyde mainly affects the first body tissue it touches causing irritation of the eyes, nose, throat, lungs or skin. These are the most common effects of overexposure:

  • Teary eyes, burning nose, sore throat, coughing, and headache. Direct contact with liquid glutaraldehyde severely irritates the eyes and can cause permanent eye damage.
  • Glutaraldehyde can remove your skin's natural protective oils. This can irritate the skin and cause dermatitis (skin rash), with dryness, redness, flaking, and cracking of the skin. Glutaraldehyde easily soaks through ordinary clothing and can severely burn the skin beneath it. Repeated skin contact can also cause an allergic skin reaction, with redness, itching, hives, and blisters.
  • The vapor can irritate the lungs, causing chest pain and shortness of breath.

Repeated exposure to even low levels of glutaraldehyde can cause asthma. A person who has developed asthma can react even to very small amounts of glutaraldehyde or other irritant chemicals. It is closely related to the cancer-causing formaldehyde.
