A universal measuring device pinpoints exhaled particles with high-precision size resolution.
FREMONT, CA: Palas GmbH, an expert for aerosol technology, has requested a patent for measuring device that helps in the immediate detection of particle concentration in exhaled air on August 27, 2020. With the help of this innovative, universally applicable measuring device, the number and size of aerosol particles may be determined quickly.
"With this product we are setting standards in the development and production of aerosol measuring devices of breathing air," said Dr Maximilian Weiß, CEO of Palas GmbH. "Latest technologies, combined with our extensive expertise in the field of aerosols, make this exhalation device particularly reliable and accurate. It can thus help to detect so-called 'superspreaders'. This can make a decisive contribution to containment, especially during the current COVID 19 pandemic".
Palas® was scientifically considered by renowned experts like Dr Gerhard Scheuch, the former president of the International Society for Aerosols in Medicine, as well as by the two lung specialists Prof. Dr Dieter Köhler and Dr Thomas Voshaar.
What role do aerosols play in the transmission of diseases like COVID-19?
Aerosols are a mixture of gas and solid and liquid components. While the larger exhaled droplets sink into the ground faster, smaller particles circulate in the air for the longest. In its profile on coronavirus disease-2019, the Robert Koch Institute says that aerosols that are produced when people talk, cough, or sneeze play the main role in the transmission of SARS-CoV-2: for instance, when many people gather in insufficiently ventilated indoor spaces.
The World Health Organization (WHO) has already recognized the risk of spreading SARS-CoV-2 through aerosols. In a signed statement to the WHO, around 240 scientists had pointed out that aerosol transmission has a substantial impact on the current pandemic situation.
The Palas GmbH contributed its long-standing expertise in the measurement of aerosol particles to the development of this new exhalation measuring device. In July 2020, the company had developed a new mask test laboratory along with the independent testing service provider TÜV NORD and BASF on the innovation campus of BASF in Shanghai, where Palas® testing devices are applied. The initiative hence supports the German Federal Ministry of Health in the acquisition of masks from China for medical and non-medical reasons.
