21 Ternary/Quaternary Gradients Blend Assist You need different concentrations of modifiers in your analysis, would like to have just one stocksolution and do online dilution to profite from the quaternary mixing capability of your pump? Here is a simple tool BlendAssist! Water Water 1% TFA Desired method conditions - example: 1. 5 to 95% gradient of ACN with 0.1% TFA in Water and 0.08% TFA in ACN % gradient of ACN with 0.5% TFA in Water and 0.4% TFA in ACN Without BlendAssist you need to either pre-mix the required solvents or by using stock-solutions of TFA in Water and ACN to program complex gradients (%A, B, C, D). ACN ACN 1% TFA With BlendAssist: just program your binary organic/aqueous gradient and define the dilution factor! Page 21
