Taschenbuch. Zustand: Neu. Neuware - WHY YOU NEED THIS BOOK ON YOUR LAB BENCH- Instant Problem-Solving: No generic theories. When you encounter a split peak, a pressure spike, or baseline drift, this book acts as an immediate diagnostic engine to fix the issue on the spot.- ICH Q14 & Q2(R2) Ready: Most chromatography textbooks on the market are outdated. This guide is fully built around modern global regulatory expectations, ensuring your validation protocols effortlessly breeze through audits.- 10 Real-World Blueprints: Includes 10 complete case studies covering actual lab nightmares, from UHPLC-to-HPLC method transfer failures to stability-indicating assay designs.HOW THIS BOOK IS ENTIRELY DIFFERENT- High-Density over High-Volume: Standard reference books are 600 pages of academic history and dense calculus. This is a 116-page, fast-access tactical playbook built specifically for active industry professionals. It contains 100% execution, 0% fluff.- Highly Visual Architecture: Instead of endless walls of text, complex chemistry is translated into highly intuitive mode-selection matrices, step-by-step troubleshooting flowcharts, and clear decision trees.- Built for the 'Cost of Failure' A single failed validation study or delayed regulatory submission costs companies thousands of dollars. This book is engineered to get your method right on the very first injection, saving massive amounts of instrument time and solvent. …

Taschenbuch. Zustand: Neu. Neuware - See how HPLC really works - then use it to develop, troubleshoot and validate with confidence.The Illustrated HPLC Comprehensive Guide skips the dry academic detail and gives you clear, visual blueprints to optimise instrumentation, develop robust methods and handle system validation in a regulated laboratory.What makes it different: - A visual-first approach: see how mobile phases, temperature and analyte chemistry interact inside the column through intuitive visual breakdowns- Practical troubleshooting: learn to read a failing chromatogram like a map and diagnose fronting, tailing, ghost peaks and split peaks without days of trial-and-error- Built for regulated industry: related substances, system suitability, column selection and forced degradation - the practical compliance topics standard textbooks leave outWho it's for: pharmaceutical scientists, quality control analysts, method developers and chemistry students who need practical results fast.Part of the Practical Pharma Science(TM) series - applied knowledge for pharma professionals.- Mirela Gorjanu, Practical Pharma Science(TM).…

Taschenbuch. Zustand: Neu. Neuware - Method development is not about random experimentation, it is a decision tree. If you get the order right, the method nearly builds itself. HPLC Method Development -A Step-by-Step Practical Guide for Every Analyte Type takes you from the desk to a fully validated method, providing a clear, no-fluff protocol for every analyte class you will encounter in the pharmaceutical industry.Whether you are struggling with a complex mixture, a tailing basic compound, or a challenging peptide, this guide provides the levers that matter.Why This Book is Essential for Your Lab- Highly Illustrated & Decision-Driven: Move away from trial-and-error. Learn to use the Universal Decision Matrix to define your mode, column, and starting pH before you ever touch the instrument.- Bench-Ready Protocols: Every chapter offers a step-by-step protocol tailored to specific analyte classes: Non-Polar, Polar, Acid, Base, Zwitterion, Chiral, Peptide, and Oligonucleotide.- Master Design of Experiments (DoE): Don't just guess, map your success. Includes two complete, hands-on chapters on DoE, showing you how to find the global optimum and define a robust Method Operable Design Region (MODR) that satisfies modern regulatory expectations.- Troubleshooting Detective Stories: Learn to recognize symptoms instantly. From 'Everything elutes at the void' to 'Peak splitting,' each troubleshooting section provides the likely cause and the first fix to get you back on track immediately.- Real-World Case Studies: Learn from 10 practical appendices that walk you through complete molecules, taking them from a problematic sample to a fully validated, regulatory-ready method.What's Inside: - The Analyte Toolkit: Master the two numbers that run everything, log P (retention) and pKa (pH control).- The 'Grand' Decision Tree: Learn the four-step logic (Size ? Chirality ? Polarity ? Charge) that guarantees you select the correct mode every time.- Critical Pair Focus: Learn to name your 'critical pair' during scouting so every subsequent optimization decision targets the exact separation you need.- Regulatory Compliance: Packed with ICH Q14-aligned guidance, helping you build methods that are robust by design, not by luck.Who Should Read This This book is the definitive desk reference for analytical chemists, QC scientists, and pharmaceutical researchers who need to produce robust, reproducible, and compliant HPLC methods efficiently.Stop wasting time in the lab. Learn the decision logic that turns complex problems into validated solutions.…
