Nettet10. jun. 2008 · Then, applying linear solvent-strength (LSS) theory, the predicted retention times for test analytes were used to find other optimal gradient times for those analytes. Satisfactory predictions of gradient retention times for test analytes were obtained at gradient times different from those applied for model analytes. 1 Introduction Nettet28. mar. 2024 · where φ 0 is the fraction of organic modifier in the mobile phase at the beginning of the gradient, t p is the time when the gradient reaches the column inlet, β = Δφ/t g is the slope of the gradient with Δφ being the change in modifier fraction between the beginning and end of the gradient, and t g is the duration of the gradient.
