SGS is the world\u2019s leading inspection, verification, and quality control agency. SGS is recognized as the global benchmark for quality and integrity. Recently, SGS is expanding its range of services in the field of indoor air quality. The focus lies on the planning, implementation and validation of measures to improve indoor air with focus on aerosol concentration. The technology of Palas\u00ae, the expert in aerosol spectrometer from Karlsruhe, Germany is used for this purpose.<\/p>\n

Indoor Air Quality Is Closely Related to Human Health<\/strong><\/p>\n

Nowadays, the importance of indoor air quality has increased dramatically. In the context of how COVID ravaging the world, the realization that aerosol-borne viruses are probably the most significant way of transmitting infections shows how important proper air hygiene is. The primary challenge now is to develop suitable measures and specific, sustainable ventilation concepts. This requires qualified experts in the field of indoor air quality as well as suitable measurement methods and technology \u2013 individual and on-site. In addition to the conception and implementation, it is important to monitor the actual effectiveness of the measures. For this purpose, the SGS now offers services for assessing and evaluating the air-hygienic indoor conditions. High-precision measuring instruments AQ Guard and aerosol generators PAG 1000 from Palas\u00ae are used for the corresponding measurements.<\/p>\n

Palas\u00ae Offers Complete Measurement Services<\/strong><\/p>\n

The SGS uses the Palas\u00ae AQ Guard aerosol spectrometer with the advanced single particle aerosol distribution spectrometer technology (SPADS) to measure aerosol concentrations in the primarily virus-relevant size range of 0.18-0.5\u00b5m based on the research. AQ Guard can measure the air quality based on the particle density and indoor CO2<\/sub> concentration. The Palas\u00ae PAG 1000 portable aerosol generator additionally enables the simulation of room use conditions by generating different test aerosols. With the combination of AQ Guard and PAG 1000, the detection mechanism can evaluate the working efficiency of air improvement equipment (such as air purifiers) by detecting changes in the concentration of indoor particulate matter within a certain period of time. Wolfgang Schreier, Division Manager Non-Lab at the SGS Institute Fresenius has shared that the expertise of Palas\u00ae regarding the generating and measuring of aerosols is of great value to them. Also, the combination of the AQ Guards and the PAG 1000 is ideal for use on-site with their customers.<\/p>\n

Compact AQ Guard Provides Precise Measurements<\/strong><\/p>\n

AQ Guard, currently the most advanced compact analyser for determining indoor air quality, continuously and reliably analysis air-borne fine dust particles in the range 175 nm -20\u00b5m. A newly developed single particle aerosol distribution spectrometer (SPADS) calculates PM values based on single particle optical light scattering, taking signal duration and shape into account. Sensor system and algorithms were developed based on the technology of the EN 16450 certified Fidas\u00ae 200. The ambient version achieves precision comparable to type approved analysers, which makes AQ Guard stand out compared to similar devices.<\/p>\n

\"\"<\/p>\n

The Autonomous PAG 1000 Is Flexible for A Wide Range of Applications<\/strong><\/p>\n

The autonomous portable aerosol generator PAG 1000, newly developed by Palas\u00ae, offers maximum flexibility for the generation of droplet aerosols, for example, from DEHS particles, especially also at low concentrations. The generator is small and with a weight of only 5 kg quite handy; being battery-powered makes it independent and quickly ready for operation. The fact that no compressed air connection is required demonstrates its flexible application options even more. A battery charge in PAG 1000 is sufficient for one working day and if needed, the device also operates on mains operation.<\/p>\n

Palas\u00ae China will participate in the China High-Tech Expo on Meteorological Modernization 2021 at the Shenzhen Convention and Exhibition Center form May 20th<\/sup> to 22nd<\/sup>, 2021. Palas\u00ae will bring a variety of instruments to the exhibition, including advanced nano-particle measurement system SMPS scanning mobility particle size spectrometer, aerosol spectrometer system Fidas\u00ae 200 series, and air quality monitor AQ Guard series. You are more than welcome to come and visit, Palas\u00ae will look forward to your arrival at the 3L38 booth!<\/p>\n
