HPLC Peak Separation Decoded - Resolution, Selectivity & Co-Elution Solved

Peak Separation Decoded

Resolution, Selectivity & Co-Elution, Solved

A practical system for fixing poor resolution, co-elution, and selectivity problems in HPLC.

Description

Two peaks won't resolve. You've adjusted the gradient, swapped the column, changed the buffer and something else broke. Solving separation problems by trial and error burns weeks of instrument time.

This guide replaces guesswork with a decision framework: read what the chromatogram is telling you, identify whether the problem is selectivity, efficiency, or capacity, and change the one variable that will actually move it.

What's inside

•    A diagnostic framework for co-elution, poor resolution, and shoulder peaks

•    Which parameter to change first and which to leave alone

•    Selectivity tuning through mobile phase, pH, and stationary phase

•    Worked chromatogram examples showing each fix in action

Who it's for: Analysts developing or optimising separations who want to stop changing five things at once.

Pairs naturally with HPLC Method Development - this one solves the separation; that one builds the whole method.
