Abstract: It can sometimes be difficult to quantify the amount of polymer present in a subterranean treatment fluid, particularly at a job site. Methods for analyzing a treatment fluid for a polymer can comprise: receiving a sample of a treatment fluid comprising a nitrogen-containing polymer; placing the sample of the treatment fluid and an aqueous base in an oilfield retort; heating the sample of the treatment fluid and the aqueous base together in the oilfield retort at least until the nitrogen-containing polymer has been substantially hydrolyzed to one or more volatile nitrogen compounds; distilling the one or more volatile nitrogen compounds from the oilfield retort; and determining a quantity of the nitrogen-containing polymer in the sample of the treatment fluid based upon a quantity of the one or more volatile nitrogen compounds distilled from the oilfield retort. Analyses of other nitrogen-containing compounds may take place similarly.
