PLG

Droplet aerosols are needed for many applications in research, development and quality assurance. In particular for quality assurance and calibration of particle measurement devices, Palas® aerosol generators ensure clear results due to their reliable characterisation. In order to be able to perform practical analyses and comparisons, droplet aerosols must be generated from fluids that are also used in the real world. Fluids such as H2O, DEHS, motor oils, white oil etc. differ significantly in viscosity, surface tension and density. Depending on the fluid, different atomisation principles offer particular advantages. In the PLG system, a nozzle system developed by Palas® is used. Depending on the application, a special nozzle with heating option is used to adjust the desired particle size distribution and concentration quickly and reproducibly.

MAG

For  more than 25 years,  the Palas®  GmbH    has  distributed, modified and built monodisperse aerosol generators.

The entire accumulated knowhow in this field is reflected in the MAG  3000  and  provides  particular  advantages  to  the  user. The   MAG 3000 thereby exceeds conventional Sinclair-LaMer generators.
  • Due to the special core source developed by Palas®, no drying system, i. e. no silica gel for the drying of the condensation cores is necessary.
  • Due to the bypass technology around the core source developed by Palas®, larger particles can be generated within approx. 10 seconds.
  • Due to the new technology, only one volumetric flowmeter is necessary.
  • The mechanical separation of electric supply and particle generation ensures a maximum of safety.

AGF

For acceptance measurements of clean rooms, leak test and test of HEPA/ULPA filters

The test of high-efficiency aerosol filters of the quality H10 - U17 is tested according to international conventions with an aerosol which exhibits the predominant number of particles in the so-called MMPS range (Most Penetration Particle Size).
A high-efficency aerosol filter of the quality U17 is defined with E= 99,999995%. The MPPS range lies approximately between 50 nm and 0.4 J.m. Big particles > 1 J.m are  separated by such filters by 100 %. In order to test a filter with U17 quality, e.g. 100,000,000 particles must be fed per minute in front of the filter to ensure that behind the filter still 10 particles per minute can be proven.
Big droplets generate high mass flows and contaminate such filters in such a way that during the tests the filters are tested better than they really are due to the droplet loading.
With the sampling of particles < 2 J.m an exact isokinetic sampling is not necessary. For these reasons the AGF system has been used successfully for these applications all over the world for more than 25 years.
