Anti-Virus Testing

With the outbreak and prevalence of COVID-19, the use of quaternary ammonium salt fungicide to effectively suppress and eliminate viruses to protect human health has received more and more attention. However, whether the quaternary ammonium salt fungicide with high antiviral function can effectively kill the virus still needs to be tested for antiviral materials to get the answer.

Anti-Virus Testing

Methods

Corresponding test methods should be used according to the hydrophilic (hydrophobic) water of the quaternary ammonium salt fungicide and the external form of the quaternary ammonium antibacterial material. The common detection methods of quaternary ammonium antibacterial materials are as follows:

  • Film Contact Antibacterial Test Method

After the bacteria are in contact with the quaternary ammonium antibacterial materials for a certain period of time, the bacteria of the quaternary ammonium antibacterial materials and the blank control sample are tested for live bacteria respectively to obtain the antibacterial rate.

  • Vibration Contact Antibacterial Test Method

Increase the contact between the quaternary ammonium antibacterial materials and the test bacteria by vigorous shaking. Then compare the bacterial counts of the quaternary ammonium salt antibacterial material and the blank sample to obtain the antibacterial rate.

  • Other Antibacterial Evaluation Methods

For dissolvable quaternary ammonium antibacterial materials, the agar plate method or parallel band method can be used to determine the size of the inhibition zone to qualitatively evaluate its antibacterial properties.
