A particle size spectrometer produces a particle size distribution with very high resolution generated by the analysis of signals extracted from each individual particle detected within the instruments measurement range. (VDI guideline 3867, sheet 4 and ISO 21501-1). Measuring Method Optical particle counters are single particle measuring instruments which classify and count the number and size of particles dependent on the intensity of the light scattered by them. This method classifies the physical measurable sizes (the particle features). It provides high sensitivity and accuracy combined with fast quantity assessment. The LAP 322 series allows the simultaneous determination of particle size (represented by the scattered light equivalent diameter) and the number of particles within an concentrated aerosol. Instruments in this series are characterised by high classification accuracy and excellent resolution. 51-h l m ■ m ו LAP 322 with Sample Switching Unit SYS 520

Applications Measurement of Particle Size Distributions and Aerosol Research The high particle size resolution as well as the wide concentration and particle size measuring range are advantageous for: inhalation-toxicological experiments Օ time-resolved aerosol measurements determination of fractional efficiencies Օ environmental studies reference measurements of model aerosols Օ measurement of droplets and sprays dust measurement, powder characterization Filter Testing The LAP Series is suitable to determine the fractional collection efficiencies in a particle size range of 0.2 to 40...

Spcifications Particle Analysis Software PASWin by Topas As a result of many years of practical exprience Topas has developed this comprehensive, capable and user-friendly control and evaluation software, PASWin. This software not only provides the measuring results with ease and speed, but will also allow a desirable degree of freedom for the experienced user, e.g. to establish and edit calibration data. Fundamental characteristics are: 驕 user interface under Windows calculation of the particle size distributions (related to particle number, integral surface area, integral volume) and...
