产品介绍 Product Introduction

使用本产品的案例（仅供参考）

HPLC

We used an Agilent 1200-UV variable wavelength detector (at 280 nm) to measure caffeine and TP concentrations in natural tea nectar with HPLC (Zhou et al, 2013) and a TSK-GEL ODS-80TM (4.6 mmi × 250 nm) columnusinga semi-quantitative method. Mobile phase A consisted of CH3CN (5% v/v) in a H3PO4(0.261% v/v) solution. Mobile phase B was CH3ON (40% v/v) in a H3PO4 (0.261% v/v) solution. Elution gradient separation was performed as follows: 0-20 min with 10% mobile phase B and 90% mobile phase A; 20-20.1 min with 22% B and 78% A; 20.1-26 min with 100% B and 0% A; 26-26.5 min with 100% B and 0% A; 26.5-27 min with 10% B and 90%A; and finally held for an additional 5 min.The flow rate was 1 ml/min, and the injection volume was 2.0 ul for each analysis.
