Table 1.
Preparation product | Eluted time | Concentration | Total volume | Purityb |
---|---|---|---|---|
MCLR-GSH | 12.52 ± 0.25 min | ≈1200 μmol/La | 5∗200 μL | ≈96.8% |
MCLR standard | 18.33 min | - - - | - - - | 98.5% |
aWith 200 μmol/L MCLR served as the inner standard for quantification and assumed MCLR and MCLR-GSH had approximate protonated efficiencies. bSample purity was directly calculated by MS signal intensity and defined as MCLR-GSH/(MCLR+MCLR-GSH) ∗ 100%.
