62 multi scan in PLC

multi scan in PLC

Figure 62 : At the time when scanner could precisely rotate
a plate keeping the plate center and the rotation center at +- 0.1 mm in X and Y direction sharp we could perfectly quantitate full circle chromatograms (one sample plus internal or external standard) by structure reduction. 12 scans over the whole distance from front to front produced a perfectly corrected chromatogram with the structure error reduced by a factor of 12. To day µ-PLC multi integration does the same but much more economical in much less time on much less space and even with sharper comparability standard deviation values. Click HERE.
