Method Transfer to Core-Shell Particles
‘Old’ HPLC methods with long run times are being altered or surpassed by newer UHPLC or core-shell methods in order to save time and cost. In this application note we show how with the use of 3 simple equations transfer of older methods can be easily achieved onto newer core-shell particles. We show the example of a pharmaceutical drug and its impurities being reduced from a 30minute run time down to less than 10minutes. Using the calculations correctly means that no loss of resolution is seen even with the decrease in retention time.
