3.imimg.com4. KBr pellets/disks (for solid samples) In order to prepare a KBr pellet, follow the procedure given below: Sample/KBr ratio The concentration of the sample in KBr should be in the range of 0.2% to 1%. The pellet is much thicker than a liquid film, hence a lower concentration in the sample is required (Beer's Law).

SILICA, CRYSTALLINE by IR (KBr pellet) 7602
www.cdc.govcrystalline silica and coal mine dust should be done in accordance with the ISO/CEN/ACGIH/ASTM respirable aerosol sampling convention. Flow rates of 1.7 L/min for the Dorr-Oliver nylon cyclone and 2.2 L/min for the Higgins-Dewell cyclone have been found optimal for this purpose. Outside of coal mine dust sampling, the regulatory agencies
