Method 1403

Alcohols IV

This method is for the collection and analysis of alcohols.  The alcohols validated in this method are 2-methoxyethanol, 2-ethoxyethanol, and 2-butoxyethanol.  The sample is collected on a charcoal tube.  After collection the sample is desorbed with 1mL of methylene chloride/methanol (95:5) and analyzed by GC/FID (flame ionization detector).

The working range of the method for 2-methoxyethanol is 0.095 to 204 ppm (0.33 to 64.5 mg/m3) for a 6L sample
volume, for 2-ethoxyethanol 0.053 to 99 ppm (0.20 to 373 mg/m3) for a 1L sample, and for 2-butoxyethanol 0.3 to
36.8 ppm (1.5 to 180 mg/m3) for a 2L sample.

NOTE: This method combines and replaces Methods S79, S361, and S76. 2-Butoxyethanol (butyl cellosolve) and butyl cellosolve acetate are included in OSHA Method 83. 2-Ethoxyethanol (cellosolve) and cellosolve acetate are included in OSHA Method 79. Both methods are very similar to Method 1403.
