• Corporate Authors:
  National Institute for Occupational Safety and Health
• Description:
  Test results using the NIOSH analytical method S325 for particulate fluoride (16984488) dust are reported. The method involves collection on a mixed cellulose ester membrane filter, ashing, fusion with a carbonate mixture, and analysis by a fluoride specific electrode. Sample preparation and ashing procedures are described. Data on recovery rates from spiked samples is included. The method was unsatisfactory due to poor recovery rates and an unacceptably high coefficient of variance. [Description provided by NIOSH]
