peracetic acid concentration monitoring

Endoscopic cleaning and disinfection

The application of endoscopy in the medical field

Endoscopy was a medical term announced in 1995. With the development of endoscopic technology, it has become an indispensable important method and means in the medical field and has been widely used and expanded in many disciplines. The examination time of gastroscopy and colonoscopy has been significantly shortened, and most patients do not feel much pain. However, while bringing great benefits to mankind, the resulting hospital infections have also continued to increase, and it has become a hot topic of concern for medical, government, and society, and should be given high attention.

The application of peracetic acid in endoscopic disinfection

Endoscopy, as a kind of precision instrument that invades the human body cavity, has the characteristics of complex structure, special materials, and unique shapes, and needs to be reused, which leads to the difficulty of cleaning and disinfection of endoscopy. The Chinese Medical Association recommends that peracetic acid and chlorine-containing disinfectants be preferred. Firstly, in terms of disinfection effect, peracetic acid can achieve high-level disinfection in 5 minutes, and the timeliness of the disinfection effect is relatively high. Peracetic acid does not produce dust staining problems during use, and can reach the sterilization level in the fastest 10 minutes. Secondly, peracetic acid is less affected by organic matter during the disinfection process, especially after following the current sequence of disinfection first and then cleaning and disinfection, it is the best choice for disinfectants.

The concentration of peracetic acid used for disinfection

Using a peracetic acid concentration of 2000-3500mg/L can achieve the effect of killing pathogenic bacteria on the surface of objects, can inhibit the self and infection of pathogens, and can also achieve the effect of effectively killing bacteria and cells, and using a concentration of 2000-3500mg/L will not cause corrosion to the surface of the object or damage to the internal organs.

Monitoring the disinfection concentration of peracetic acid

The peracetic acid sensor imported from Germany RG is a membrane-coated sensor with a double-electrode measurement system, which is resistant to surfactants. It has been widely used in the monitoring of peracetic acid concentration in the disinfection of medical devices and has been well received by many users.

North Measurement and Control, as the China service center of Germany RG, imported original disinfectant sensors that can measure a wide range of parameters, such as peracetic acid, available chlorine, residual chlorine / chlorine dioxide, total chlorine, ozone, hydrogen peroxide, chlorite, and so on. It is applied in a variety of fields.
