LC Solvents for JP, USP, Ph. Eur.
The solvents for the Pharmacopoeia General Test (for LC) comply with the reagent grades of the Japanese Pharmacopoeia, the United States Pharmacopeia (USP), and the European Pharmacopoeia (EP, Ph. Eur.). It supports global pharmaceutical tests. USP and Ph. Eur. have different grades for different applications within the same solvent type, and the absorbance measurement wavelength range and content specification values are defined according to the grade. Our solvent for the Pharmacopoeia General Test (for LC) grade is assured up to the highest grade of both USP and Ph. Eur. And we assure our own test items and stricter specifications in addition to the specifications of each pharmacopeia.
Features
- Compatible with the solvent standards of the Japanese Pharmacopoeia, USP (ACS), and Ph. Eur.
- In addition to General Use, assures up to Specific Use (UV Spectrophotometry, LC Suitability) grades. (USP)
- Assures R1 for acetonitrile and R1 and R2 for methanol. (Ph. Eur.)
- We have added our own test items and specification values, and some of them are assured to be stricter than the specifications of each pharmacopeia.
