HPLC - SlideShare

larger molecules simply pass by the pores as they are too large to enter the pores. Larger molecules therefore flow through the column quicker than smaller molecules, that is, the smaller the molecule, the longer the retention time. separates particles on the basis of molecular size (actually by a particle's Stokes radius or Stokes-Einstein

Feb 28, 2018 · Serial dilutions (1:1, e.g. 500 μl:500 μl) were performed using low binding pipette tips with Eppendorf Protein LoBind ® tubes. This method provided a large volume to surface ratio and minimal pipetting errors. We then placed the samples in silanized glass vial inserts in HPLC vials to carry out the SE-HPLC experiments.

Causes of Retention Time Drift in HPLC - Crawford Scientific

Sep 19, 2017 · First – one should establish the cause of the drift – is it a result of changes in flow rate or a chemical change to eluent or HPLC column. This is fairly easily determined; if the retention time of the analyte peaks AND the t0 marker (or solvent injection disturbance) change to the same degree, then the problem is more likely to be related
