How to detect 75% alcohol concentration quickly and accurately?

In the face of the ever-changing new type of Covid-19, the elimination of the virus is an imdportant link in the prevention and control of the epidemic, and the concentration of alcohol is critical to the elimination effect. The national standard disinfection alcohol has an alcohol content of 75%, and the alcohol content does not meet the standard. Can not achieve the effect of disinfection and epidemic prevention, but how to quickly and accurately detect the 75% alcohol concentration?

Commonly used alcohol measurement methods are: hydrometer method, gas chromatography, bulk density method。

Hydrometer method: The on-site volume calibration and sample verification steps are cumbersome, the equipment is cheap and the calibration is difficult, which is not conducive to on-site testing.

Gas chromatography: high precision, expensive equipment, requires professionals to operate and cannot achieve on-site verification.

Bulk density method: The measurement must be performed in a constant temperature laboratory environment, and must be operated by professionals. On-site detection cannot be achieved.

But our company adopts microwave transmission method: the measurement is fast, accurate, and efficient. The equipment is small in size, portable, and can be inspected on site. This instrument can conveniently, quickly, accurately and efficiently determine the moisture content of alcohol. The single measurement time is within 2-3 seconds, and the digitalization of the moisture content of alcohol can be realized. It can be used in epidemic prevention and anti-epidemic laboratory hospitals, field inspections, and environment Eliminate and kill, provide strong support for epidemic prevention and fighting.
