WitrynaHow to Improve Resolution in HPLC Increase N (efficiency) by: Increasing column length Decreasing particle size Reducing peak tailing Increasing temperature Reducing … WitrynaHPLC is the workhorse method for phenolic separation. However, conventional HPLC methods provide insufficient resolving power when faced with the complexity of real-world phenolic fractions. This limitation has been traditionally circumvented by extensive sample fractionation, multiple analysis methods and/or selective detection strategies.
