APPLICABILITY: For three-liter sample, the working range for acetone was 0.378 to 41.4 ppm (0.92 to 100.2 mg/m3 ). For a 10-L sample the working range for methyl ethyl ketone was 0.092 to 10.2 ppm (0.275 to 30.5 mg/m3 ), for 2-pentanone was 0.077 to 8.67 ppm (0.276 to 31.1 mg/m3 ), for methyl isobutyl ketone was 0.066 to 6.83 ppm (0.275 to 28.5 mg/m3 ), for 2hexanone was 0.066 to 7.45 ppm (0.275 to 31.1 mg/m3 ), for diisobutyl ketone was 0.052 to 5.07 ppm (0.308 to 30.1 mg/m3 ), and for cyclohexanone was 0.075 to 9.79 ppm (0.300 to 39.2 mg/m3 ). INTERFERENCES: Any compounds with similar retention times as the analytes of interest. Alternate columns include Rtx-1 and Rtx-5 or equivalent capillary columns. OTHER METHODS: This method was developed as part of an update for NMAM 1300, issue 2 (dated 15 August 1994) [1]. NMAM 1300, issue 2 was based on NIOSH Manual of Analytical Methods, 2nd edition methods S1, S18, S19, S20, S178, and S358. This method includes: lower LOD/LOQ values for each analyte, improved DE recovery results for each analyte (at lower levels), inclusion of methyl ethyl ketone and methyl isobutyl ketone in the method by the use of a different sorbent tube (Anasorb CMS), a 30-day storage stability study, and replacement of the packed column with a Rtx-35 fused silica capillary column.
