詳細

詳細

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. m-Xylene is widely used as a residual solvent (RS) or organic volatile impurity (OVI) in pharmaceutical formulations.[1]

アプリケーション

m-Xylene may be used as a pharmaceutical reference standard for the determination of the analyte in tablet formulations by chromatography.[2] It can also be used as a residual solvent standard for the quantification of the analyte in tablet formulations by headspace gas chromatography (HS-GC) with flame ionization detection (FID) technique.[1]

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
