使用本产品的案例（仅供参考）HPLCThe specific elution included phase A: acetonitrile: methanol = 3:1 (containing 0.01% butylated hydroxytoluene (BHT)); phase B: 100% methyl-tert-butyl ether (MTBE) (containing 0.01% BHT). The elution conditions were as follows: 0 min: A-B (95: 5); 0–10 min: A-B (95: 5); 10–19 min: A-B (86: 14); 19–29 min: A-B (75: 25); 29–54 min: A-B (50:50); 54–66 min: A-B (26:74); and 67 min: A-B (95:5). The mobile phase flow rate was 1 mL/min, and the detection wavelength was 450 nm; the column temperature was 35 ◦C.来源文献：Zhang R, Zhang J, Li C, Pan Q, Haq SU, Mosa WFA, Fang F, Zhang L, Li B.

PMID: 37299099; PMCID: PMC10255399.LC-MSThe carotenoids contents were determined using an HPLC system equipped with a  C30 column (150 ×4.6 mm, 3 μm) and a UV/VIS detector. The mobile phase consisted ofA (acetonitrile: methanol = 3:1) and B (methyl tert-butyl ether), and a gradient elution program (Lee et al., 2001) was used. The flow rate was 1.0 ml/min, and the column temperature was 40℃. The signals were detected at 450 nm. Identification of lutein and zeaxanthin was conducted on AB TripleTOF 5600 plus system equipped with an APCI source operated in the positive ionization mode. The column and temperature settings were the same as HPLC. The mobile phase was A (methanol) and B (acetonitrile: isopropanol = 1:1) with linear increase of B from 0 to 100% in 30 min followed by dropping to 0 in 10 min. The source voltage was +5.5 kV, and the source temperature was 500℃. The pressure of Gas 1 (Air) and Gas 2 (Air) was set to 50 psi. The pressure of Curtain Gas (N2) was set to 35 psi. The m/z scan range of production was set as 50–1500. 来源文献：Bian Q, Zhou P, Yao Z, Li M, Yu H, Ye L. Heterologous biosynthesis of lutein in S. cerevisiae enabled by temporospatial pathway control.

The flow rate was 1.0 mL/min, and the temperature was 25℃.
