Stop rebuilding the same HPLC answers from scratch.

Fifteen guides, toolkits, templates and simulators, in one place. $415 separately. $149 together.

It's four o'clock. The peak is tailing, the batch is on hold, and QA wants something in writing by morning.

You know the answer exists somewhere — in an SOP on a shared drive, in an application note you bookmarked in 2019, in the notebook of the analyst who left last year. So you spend ninety minutes finding it instead of ten minutes fixing it.

This library is the alternative: one place where the HPLC answers live, organized the way problems actually arrive in a lab.

What's inside

Fix what's in front of you

• The Practical HPLC Chromatogram Troubleshooting Atlas — diagnose by what you're looking at: peak shape, retention, resolution, baseline, ghost peaks, detector faults
• HPLC Peak Separation Decoded — resolution, selectivity and co-elution, solved
• The HPLC Troubleshooting Workbook — 12 diagnostic exercises from real lab problems, with worked answers

Build the method

• HPLC Method Development — a step-by-step route for every analyte type
• The Theory of Separation in HPLC — why every peak is where it is
• Illustrated HPLC Comprehensive Guide
• The Complete HPLC Visual Reference — 155+ illustrated guides across the whole analytical workflow
• HPLC — 11 Practical Courses

Validate it, then write it up

• HPLC Assay Method Validation — the complete ICH-aligned reference
• HPLC Assay Method Validation — validation report, SOP and Excel calculation templates
• HPLC Related Substances Toolkit — validation report, SOP and Excel templates

Test it before you run it

• Four interactive simulators — method development, gradient development, column selection, and how different molecular chemistries behave on a C18

Who it's for

QC analysts, method development scientists, validation leads and analytical chemists in pharmaceutical and biopharmaceutical laboratories. Written against ICH Q2(R2), ICH Q14 and USP <621>.

Who wrote it

Mirela Gorjanu, MSc — senior pharmaceutical chemist, twenty years in drug development and compliance. Every workflow in this library came out of a working laboratory, not a textbook.
