有关液相的一个名词求教 看一文章中写道 Figure 1 also shows “solvent front” retention factor values (kSF) which have been calculated based on retention times of the leading edge of the solvent peaks. Note that, for the strongest solvent (THF), a significant portion of the most analytically useful k range resides within the “presolvent-front” region of the chromatogrambetween t0 and tSF.
请问这个Ksf是什么时间，可见和死时间是不同的
For THF, the solvent front is beyond the time scale of the chromatogram (7.59min).
