1-Methyl-2-pyrrolidone

• Outline: This is an ideal solvent for GPC, which secures absorbances after heating. It secures changes of refractive infex due to moisture, peroxides, nonvolatile matters, and impurities, as well as UV absorption, making it most suitable for preparation of eluents for GPC.
