Failure report no. S157.

Details

• Description:
  Test results using the NIOSH analytical method S157 for acrylamide (79061) are reported. The technique involved collection on a solid sorbent or in a midget impinger containing water, desorption with organic solvents and water, derivatization with 1,3-cyclohexadiene or morpholine, and analysis with gas chromatography using a flame ionization detector. Data on recovery rates for charcoal (16291966), silica-gel (10193369), chromosorb-103, Tenax-GC, and Porapak-Q sorbents is included. Solid sorbents were unsatisfactory because of large pressure decreases, and midget impinger collection was unsatisfactory because the chromatographic column was not sufficiently sensitive and would not withstand repeated injections. Derivatizations with 1,3-cyclohexadiene were incomplete after 24 hours, and the morpholine derivative could not be chromatographed. [Description provided by NIOSH]
