Light blockage

Aerometrics Eclipse is a white light blockage system designed for both liquid and gas systems. The probe head includes a light source, flow cell and photodiode. The processor can accommodate two heads covering the size ranges 2-100 pm, 10-500 pm, 20-1000 pm and 50-2500 pm. The flow cells are compatible with most liquids and can be specially adapted for high-pressure environments. [Pg.474]

PMT-2120 counter uses light blockage and can count up to 3,000 particles per second. It covers the size range 1-12,000 pm with selectable 16 or 32 channels. [Pg.486]

Comparison tests between the PSS Accusizer 770 (light blockage), API Aerosizer (time of flight) and MALLS instruments (Malvern Mastersizer and Coulter LS) indicated that the MALLS instruments gave results that differ from each other and from microscopy whereas the other two instruments gave results in agreement with each other and with microscopy [167]. The choice of the Fraunhofer or Mie theory model affected the calculated size distribution in an unpredictable manner and the use of Mie... [Pg.563]

Two different types of optical instruments were employed a light blockage apparatus and a laser diffraction apparatus. [Pg.385]

Similar results were obtained with the light blockage method (HIAC), whose inadequacy for swelling measurements can be explained by too small a difference in refractive index between aqueous medium and swollen particles. ... [Pg.389]
