No.102 Analysis of catechins in tea (UHPLC)

Foods

We analyzed 4 kinds of catechins and caffeine contained in tea.

The UHPLC condition transferred from HPLC method greatly reduces injection volume, solvent usage and analysis time.

In particular, a column with an inner diameter of 2.0 mm and a length of 50 mm reduces analysis time by 85% while maintaining sufficient separation to achieve high efficiency.
