Description

General description

A certified multi-component mix of Caffeine and the common Green Tea catechins: (-)-Epigallocatechin 3-gallate, (+)-Catechin, (-)-Epicatechin, (-)-Epicatechin 3-gallate, (-)-Gallocatechin, (-)-Gallocatechin 3-gallate, and (-)-Catechin 3-gallate. This Snap-N-Shoot^® solution mix is suitable for quality control testing of Green Tea beverages or supplements by LC or LC/MS. The Snap-N-Shoot^® format and multi-component solution mix offer several advantages from added convenience with less time weighing plant extracts or powders and preparing solutions to improved efficiency from less time rerunning samples or remaking reference solutions due to different raw material purity factors. The sealed ampoule provides additional precautions for storage of these sensitive phytochemicals.
