Dibutylammonium phosphate
WebThe system consists of a μBondapak CN or Nova-Pak Phenyl column in a radial compression apparatus, eluted isocratically with methanol: water (27:73) containing 0.01 M dibutylammonium phosphate. Symmetrical, well-resolved peaks were obtained for 30 pyrrolizidine alkaloids within a 15 min elution time. WebDec 6, 2006 · WR 2721 had a retention time of about 13 minutes using a mobile phase of acetonitrile/water (22:78), 0.01 M in dibutylammonium phosphate, at a flow rate of 2 mL/min. Sensitivity of the assay was characterized to 2 μg/mL, and detector response was linear over the range of 2 to 1100 μg/mL.
