From 12 to 16 June 2022, Palas®, an aerosol monitoring expert from Germany, was invited to participate in the 12th Asian Aerosol Conference (AAC) held at the National Taiwan University in Taiwan. The conference focuses intensively on aerosol monitoring and discusses advanced instruments in the field of aerosol science and technology. Palas® brought a variety of instruments to the conference including: Fidas® frog fine dust monitor, PLG 1000 oil generator, Promo® particulate aerosol spectrometer and RBG 1000 dust aerosol generator attracted the attention of many experts and industry colleagues.
The Asian Aerosol Conference the leading platform for aerosol science and technology
The Asian Aerosol Conference has been held every six months since 1999 under the auspices of the Asian Aerosol Research Conference. It is one of the most important events for researchers and professionals in the field of aerosol science and technology in Asia. Plenary lectures, special symposia and industry exhibitions were held during the four-day conference. The conference provides a platform for the exchange of new research results in aerosol science and technology. The conference featured advanced technical discussions and advanced aerosol monitoring tools for industry, while recognising the outstanding contributions of aerosol scientists in Asian countries. Palas®, the expert in filtration efficiency testing, responded positively and brought a range of products and equipment to the show to discuss new technologies with industry experts.

· Reliable function
· Low maintenance
Applications
· Filter industry/oil separators
· Determination of separation efficiency
· Determination of fractional separation efficiency
· Loading test – HEPA/ULPA filters
· Test of cooling lubricant separators
· Comparison of particle measurement devices
· Tracer particles
· Flow visualization
Promo® Aerosol Spectrometer for Particle

RBG 1000 Dust Aerosol Generator
Low-concentration solid particle aerosols produced from powders are required for many applications in research, development, and quality assurance and for the calibration of particle measurement devices. For more than 25 years, the RBG system has been used worldwide with great success for the reliable dispersion of non-cohesive powders such as mineral dusts, active pharmaceutical ingredients, pollen, etc. in the size range of < 100 µm and with a fine fraction of < 100 nm.
Advantages
· Highest short-term and long-term dosing constancy
· Disperses virtually all non-cohesive dusts
· Easy exchange of different solid material reservoirs and dispersing covers
· Easy determination and adjustment of the mass flow
· Pulse mode
· Device easy to clean
· Quick and easy to operate
· Reliable operation
· Little maintenance required
· Reduces your operating expenses
Applications
