Research reports from S. Sangaraju and co-authors provide new insights into chromatography
Published in Medical Imaging Week, June 27th, 2009
"A simple and accurate chiral liquid chromatographic method was developed for the enantiomeric purity determination of D-nateglinide and quantitative determination of L-nateglinide in bulk drug samples. Good resolution (R-s > 6.0) between D-enantiomer and L-enantiomer of nateglinide were achieved with Chiralpak AD-H (250 x 4.6 mm, 5 mu m particle size) column using hexane and ethanol (90:10 v/v) as mobile phase at 25 degrees C temperature," investigators in Hyderabad, India report.
"Flow rate was kept as 1.0 mL min(-1) and elution was monitored at 210 nm. The effects of the mobile phase composition, the flow rate and the temperature on the chromatographic separation...
