Examples of using this product(for reference only)
UHPLC
UHPLC system (Shimadzu, Japan) consisted of a model LC30AD pump and a model SIL-30AC autosampler with a Phenomenex Kinetex C18 column (100 mm × 2.1 mm, 1.7 μm).The chromatograph was equipped with a gradient mobile phase. Mobile phases were water with 0.1% of formic acid (A) and acetonitrile with 0.1% of formic acid (B). The gradient used was as follows: 0.01 min, 5% B; 0.01–3 min, 5–25% B; 3–5 min, 25–30% B; 5–12 min, 30–50% B; 12– 18 min, 50–100% B; 18–22 min, 100% B; 22–22.1 min, 100– 5% B; 22.1–27 min, 5% B. The injection volume of sample was 2 μL. The flow rate was 0.3 mL/min and the column temperature was 35℃. The Q-TOF-MS system (AB, America) with an ESI source was performed in positive mode and negative mode. The parameters of ESI–MS were set as follows: ion source gas 1 (50 psi), ion source gas 2 (50 psi), curtain gas (35 psi), temperature (500℃), ion spray voltage floating (5500 V), declustering potential (100 V), collision energy (10 eV).
