Examples of using this product（for reference only）

HPLC

HPLC analysis of chlorophyll and carotenoids were carried out using an Agilent 1260 instrument with a VWD detector . Samples (10 μL) were separated at 30℃ on a C18 column (150 mm × 3.9 mm i.d.; 4 μm particle size) using isopropanol and 80% acetonitrile–water at a flow rate of 0.5ml/min.

HPLC

HPLC analysis of carotenoids was carried out using an equipped with a variable wavelength detector (VWD). Samples (10 μL) were separated at 30℃ on a C18 column (150 × 3.9 mm id; 3 μm particle size) using isopropanol and 80% acetonitrile-water at a flow rate of 0.5 mL min?1 ; the absorbance was measured at 448 and 428 nm.
