This alditol acetate mixture contains four pentaacetate alditols for the qualitative identification and quantitation of unknowns. This mixture is ideal as a standard for the analysis of polysaccharides, especially for plant cell wall polysaccharides. All materials are analyzed to verify their identity and to determine their purity. All analytes are 98+% pure. This standard is accurately prepared by gravimetric technique (+/- 0.5%) and all glassware is class A rated. Ampules are purged with nitrogen/argon before and after filling and chilled before being flame sealed. Store ampules sealed as received and process without delay immediately after opening the ampule.
