Aerosol Spectrometer LAP 323

With the new single particle scattering light spectrometer LAP 323 the innovative Dual Wavelength technology of Topas GmbH for particle size and number determination is implemented.

Standards

The use of two laser diodes with different wavelengths allows a high-resolution detection of even small spherical particles and their accurate classification. The application of two light sources with monochromatic light of different wavelengths for scattered light generation has the advantage to level out discontinuities i.e. that particles whose size falls within this range are difficult to distinguish from one another. Additionally, the aerosol spectrometer is characterized by integrated sampling, intelligent volume flow control and compact design. The Laser Aerosol Spectrometer LAP 323 meets all technical requirements for aerosol spectrometers as described in ISO 21501-1 and VDI guideline 3867 part 4.
