2流体ノズルを用いたウイルスサンプラの検討

抄録

In this study, we designed and assembled a virus sampler using a two-fluid nozzle as the dissolution part, as a new method to dissolve microdroplets containing viruses floating in the air into a liquid. In our design, the two-fluid nozzle sucks up the test gas along with the liquid and mixes the test gas and the liquid. In addition, we used sodium chloride as a pseudo-virus and evaluated collection ratios with and without the two-fluid nozzle. As a result, we confirmed that the collection ratio was improved by 35±2.6 % in the case with the two-fluid nozzle compared to the case without the two-fluid nozzle.
