Sigma-Aldrich Show all KNAUER HPLC Method Converter : Validates if column changes are compliant with regulatory standards (like USP 621) and flags deviations in red. Sigma-Aldrich Supelco® Calculator : Provides estimates for run time savings and solvent reduction when moving from HPLC to UHPLC. Waters Columns Calculator : Focuses on converting HPLC methods specifically to UPLC (Ultra-Performance Liquid Chromatography) formats. ACE Translator Tool : A free utility for translating both isocratic and gradient methods between different systems. lcms.cz +6 Key Benefits of Method Conversion Reduced Analysis Time: Modernizing to shorter columns or smaller particles (like core-shell technology) can reduce run times by up to 70-80%. Solvent Savings: Switching from a 4.6 mm to a 3.0 mm diameter column can save nearly 60% of solvent consumption. Higher Sensitivity: Narrower columns and smaller particles often result in sharper, more concentrated peaks, improving signal-to-noise ratios. YouTube +4 Practical Considerations & Risks Selectivity Shifts: Even with identical chemistries, changing particle size or morphology (e.g., from fully porous to core-shell) can cause subtle shifts in selectivity. Instrument Limitations: Older HPLC systems may have high hplc column converter
"Saved us nine minutes per injection," Leo grinned. "In a 100-sample batch, that’s fifteen hours of lab time." * Flow Rate(mL/min) 0
An is a specialized software tool or online calculator designed to adapt experimental parameters when changing column dimensions or particle sizes. Key Functions Estimates new backpressure
The trace began to crawl across the monitor. In the old method, the main peak usually drifted out at the eight-minute mark. But at 45 seconds, a sharp, symmetrical spike pierced the baseline. Then another. At 80 seconds, the final impurity eluted with perfect separation.
