History
Dipropylene glycol methyl ether is one of the most commonly used propylene glycol ethers in industry and is discussed in a recently published NEG/NIOSH document. Dipropylene glycol methyl ether is a collective term describing a mixture of structural isomers. The method specifies collection of the vapors on activated charcoal, desorption of the charcoal with carbon disulfide, and analysis by GC using flame ionization detection.
