Green tea-containing solid oral dosage form

Description

• General description: One unit of SRM 3256 contains five packets of powdered material, each containing approximately 2.5 g.SRM 3256_certSRM 3256_SDS
• Application: The SRM is primarily intended to validate analytical methods used to determine catechins, xanthines, andtoxic elements present in solid oral dosage forms in cluding green tea and similar matrices. Additionally, it is also suitable for ensuring quality while assigning values to in-house control materials.
• Features and Benefits: The certified value of the SRM was determined by calculating the mass fraction values, which were obtained through two methods:Ultraviolet absorbance detection (UV) Mass spectrometry (MS) Certified and reference mass fraction values for catechin,gallocatechin, gallic acid, theanine, and other elements are provided on a dry-mass basis and values are metrologically traceable to the SI unit of mass expressed as micrograms per gram.The NIST certificate is provided with expiration certificate, storage, handling, use,and maintenance instructions.
• Other Notes: Certified for the analytes listed below. See certificate for values and more detailsPhytochemicals: (–)-Epicatechin, (–)-Epicatechin gallate, (–)-Epigallocatechin, (–)-Epigallocatechin gallate, (–)-Gallocatechin, (–)-Gallocatechin gallate, (–)-Gallocatechin gallate, (+)-Catechin, caffeine, Gallic acid, L-Theanine, Theobromine, TheophyllineTrace Metals: Arsenic (As), Cadmium (Cd), Lead (Pb), Mercury (Hg)Matrix Group: Botanicals
