Factors that can have an effect on robustness when performing chromatographic analysis include:
- stability of test and standard samples and solutions
- reagents (e.g. different suppliers)
- different columns (e.g. different lots and/or suppliers)
- extraction time
- variations of pH of a mobile phase
- variations in mobile phase composition
- temperature
- flow rate
