Analysis of NMP in batteries by GC-FID

N‑methyl‑2‑pyrrolidone (NMP) is a critical solvent in lithium‑ion battery manufacturing, but residual NMP in electrode materials presents both performance and regulatory challenges. This application note describes a validated GC‑FID method for the quantification of residual NMP in battery electrodes, developed to support quality control in the manufacturing process and reduce exposure. Nitrogen was used as the carrier gas within this application due to its ability to be produced renewably and to avoid current issues over helium supply

Key learnings from this application note:

  1. Discover the rigorously validated method for NMP in batteries with excellent linearity, LOQ and recovery using the SCION Instruments GC-FID together with the SCION-WAXMS column.
  2. DMF (Dimethylformamide) and DMSO (Dimethylsulfoxide) are commonly used alternatives to NMP our robust method has been designed to enable measurements of these compounds.
