摘要：
The presently disclosed subject matter relates to methods for quantifying the amount of N-methyl-2-pyrrolidone (NMP) in a sample. In one exemplary embodiment, a method for the quantification of N-methyl-2-pyrrolidone (NMP) in a sample includes introducing a sample that includes 1,3-butadiene and NMP, if any, into a gas chromatography system coupled to a nitrogen phosphorous detector to produce a first signal; and comparing the first signal to a second signal produced from a standard of a known NMP concentration, to quantify the amount of NMP in the sample, where the sample is not concentrated for NMP prior to the introduction of the sample into the gas chromatography system.
