title: Microcolumn chromatographic cleanup and GLC determination of 11-methyl-16,16-dimethylprostaglandin E2 in polyethylene glycol 400 solutions.
abstract: An analytical procedure is described for the GLC determination of 11-methyl-16,16-dimethylprostaglandin E2 in aqueous polyethylene glycol 400 solutions. Because of the nature of the carrier matrix, sample cleanup was required prior to GLC separation. Separation was achieved using a diethylaminoethylcellulose microcolumn. This procedure has proven to be amenable to routine analysis.
