Define the following terms used in HPLC:                      (d) sampling loops             (e) bonded-phase packing             (f) gel filtration

Which is better HPLC system Agilent 1290 Infinity II LC or Nexera Series UHPLC? Explain

Why are some of the detectors listed unsuitable for HPLC?

Retention time is the time taken for the mobile phase to reach the detector.   True False

use deminsional analysis

The standard graph contains absorbance values greater than 1.00 Is there a positive error, negative error, no effect, or error could not be determined In terms of the Linearity of the standard curve?
