55 identif./ overspray


Figure 55 : A fundamental problem in standard TLC / HPTLC
is the fact, that overlapping substances can drastically change the position (Rf) of a substance of interest - in figure 55 the thick black line. This falsifies identification and quantitation.
Way out: much better separation efficiency, multi phase separation, MMD (manual multi development fort instance by µ-PLC). See HERE.
