Troubleshooting HPLC Mobile Phase Issues

The HPLC mobile phase impacts retention and selectivity of analytes. Therefore, mistakes in mobile phase design and preparation will lead to considerable problems. This on-demand webinar will cover the areas of mobile phase preparation and design that are most likely to result in method errors and ensure that you have the tools to identify problems before they occur.

Topics include:

  • Overview of mobile phase
  • Flow rate
  • Importance of pH
  • Typical components
  • Buffers (type, pH, molarity)
  • Organic
  • Ion pairing agents
  • Mobile phase preparative errors (pH adjustment, mixing, filtration, degassing)
  • Gradient elution (overview of effect of 5 main parameters, differences in pump gradient mixing, dwell volume)
