A failing method always has a cause.
Unexpected results, inconsistent data, a method that suddenly no longer meets validation criteria. These problems often feel random, but they never are. Analytical troubleshooting is systematic detective work to find the root cause, not a quick fix.
Analytical troubleshooting is therefore relevant in every sector we serve.
Fixing a symptom is not the same as solving a problem.
The temptation with a failing method is to quickly adjust a parameter until the results look right again. That approach hides the problem instead of solving it.
01

Distinguishing between method and instrument
Is the problem the method itself, the instrument, the sample, or the operator? Each potential cause requires a different diagnostic approach.
02
/
Recognizing changes over time
Methods that were stable for years can fail due to subtle changes; a new column batch, a different reagent supplier, or equipment wear and tear.
03
/
Reproducibility of the problem
A problem that does not occur consistently is harder to diagnose than one that occurs every time. We bring structure to seemingly random deviations.

From inexplicable result to confirmed cause.
Our approach to troubleshooting is systematic; we rule out potential causes step by step until the actual source is found.
01
/
Defining the problem precisely
When did the problem first occur, how often does it happen, and what has changed during that period? A precise problem description is the foundation of every diagnosis.
02
/
Systematically ruling out potential causes
We go through the method, instrument, sample, and operator step by step to isolate the most likely cause.
03
/
Conducting targeted experiments
We use targeted tests to confirm or reject each hypothesis until the root cause of the problem is established.
04
/
Confirming the root cause
We repeat the confirmation test to ensure that the identified cause fully explains the problem.
05
/
Documenting solutions and prevention
We provide not only the solution, but also recommendations to prevent the problem from recurring in the future.
