For people who have just left the test center, they have a nose swab taken, such a short stop at Mr. van Wees’ office is like a sip of fresh air and a totally fun experience.
Soraya Assoud is scheduled to go to Spain, which requires a negative coronavirus test. This is how the tests in Mr. van Wees’ cabin work: a man walks into an enclosed space, turns on a powerful air purifier, creating an air vortex in the cabin. This means that the air in the room is cleaned first. Then the person who entered can yell, yell or sing at will.
The air is cleaned a second time before the subject leaves. The exhaled air particles are then collected, moisture removed, and measured in nanometers. Van Wees says: Although a large number of particles are found on a person’s clothing and in the air they exhale, the infection is distinguished by the fact that it is made up of particulate particles.
The process takes about three minutes. The inventor believes that the test method he devised would be useful near concert halls, airports, schools, and offices.
