National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Acrylamide from Matheson, Coleman, and Bell (Failure Rept. No. S157).

PB81240665

Publication Date	1981
Page Count	8
Abstract	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, silica gel, 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.
