COLUMN:
Capillary, fused silica, 30-m x 0.53-mm ID; 3:m film crossbonded® 35% diphenyl-65% dimethyl polysiloxane or equivalent
CALIBRATION:
Solutions of methyl acrylate in CS2
RANGE:
1.9 to 172.3 µg per sample [1]
ESTIMATED LOD: 0.5 ug per sample [1] PRECISION ( þ r ):
0.007 [1]
APPLICABILITY: The working range is 0.11 to 9.79 ppm (0.39 to 34.5 mg/m3 ) for a 5 L air sample [1]. Method is applicable to any sampling environment where methyl acrylate is present in the vapor state.
INTERFERENCES: Any compound eluting during the analysis and having a similar retention time.
OTHER METHODS: This method udates NMAM 1459 [2] which is Method S38 from the 2nd edition of the NIOSH Manual of Analytical Methods [3]. Improvements include but are not limited to the following: smaller volume of desorption solvent required, desorption efficiency (DE) results were improved by using a different solid sorbent tube, and a lower LOD/LOQ was established [1]. A storage stability study was completed and was found acceptable with a 105.3% recovery after 4 weeks at 5°C [1].
