water is more polar than acetonitrile.but in reverse phase chromatography peaks elute earlier when we increse Acetonitrile.what is the reason.

Answer Posted / paresh jobanputtra, piramal(ah

Actually What happen,When we mix Acetonitrile with buffer then VISCOSITY is decresed of mobile phase.
"As viscosity decreased, Mass transfer of solute particle with stationary phase is decreased"
So but obvious component elute earlier.

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
