Chromatography Troubleshooting
Symptom-first guides for HPLC, UHPLC, GC and LC-MS - what the instrument is telling you, how to isolate the cause, and what to change.
How to Use Them
Start From the Symptom, Not the Theory
Most troubleshooting material is organized the way a textbook is: by component, by principle, by chapter. That is the wrong index for someone standing at an instrument at four in the afternoon. You do not know yet that it is the guard column - that is the thing you are trying to find out.
So the library is organized by what you can actually observe. Pick the category that matches what the instrument is doing, find the symptom, and follow it back through the causes worth ruling out first.
The guides are written by our scientists and are open to everyone. No account, no sign-up, no email wall - a troubleshooting guide behind a form is a troubleshooting guide nobody reads in time.
Free to read, indexed by symptom, and written for the moment the run is already going wrong.
What a Guide Contains
Written to Be Used Standing Up
Each guide follows the same shape, so you are not re-learning the format every time you open one.
Causes, in the Order Worth Checking
The likely causes ranked by how cheap they are to rule out, so the five-minute check comes before the one that costs you a column.
Something You Can Change
Each cause ends in an action - a setting, a part, a preparation step. A guide that stops at the explanation has not finished the job.
