Usually measured in mL/min, the flow rate affects the "backpressure" of the system and the speed of analysis. While higher flow rates speed up the process, they can reduce resolution and strain the column. Column Temperature

Sudden pressure spikes during a run indicate the mobile phase viscosity has peaked or particulate matter has trapped the column frit. Lowering the flow rate during high-viscosity blend ratios can prevent automated pressure trips. If you want to tailor this further, tell me: What is the you are separating (e
This section determines how the sample is introduced into the flowing mobile phase.
Advanced applications sometimes require simultaneous programming of both flow rate and solvent composition. This approach can be particularly useful for preparative chromatography or when working with viscous mobile phases, where gradual flow adjustments help maintain system pressure within safe limits while delivering the desired separation performance.
