"WebMy major issue here is carryover after the highest calibrator for these analytes. Carryover is ~30%. Gradient starts at 90% MPB and drops to 0% over 13 minutes and a hold for 5 mins at 0% MPB. Isocratic holds at 10-40% MPB don't help remove the carryover. Longer holds don't seem effective either. " - Hilic carry over
