Colour density measurement of chromatograms - using opto-electric conversion and line-by-line resolution of video signal (HU 28.12.76)
The colour density of an image is measured by first converting the image into an electrical video signal. This is then resolved line-by-line; each line sampled and its signal level compared with standards. By digital conversion the signal level at each point (which is proportional to, the colour den...

| description | The colour density of an image is measured by first converting the image into an electrical video signal. This is then resolved line-by-line; each line sampled and its signal level compared with standards. By digital conversion the signal level at each point (which is proportional to, the colour density) is counted up, displayed and printed. Used for the quantitative analysis of chromatograms, elphograms, autoradiogrames, photographic reproductions or copies. The analysis method is much more rapidly than the time-consuming use of densitometers.
L'invention a trait à la mesure d'altérations de couleur. Au cours de l'évaluation automatique de chromatogrammes, elphogrammes, autoradiogrammes, électrophoréogrammes sous forme de gel, l'échantillon est illuminé ou traversé par un rayonnement de lumière visible, ultraviolette ou infrarouge, et l'image est formée sur la plaque collectrice du convertisseur opto-électrique. L'image apparaissant sur la plaque collectrice ou la plaque signal est décomposée en lignes, explorée par le faisceau d'électrons et la densité des surfaces décolorées transformée en vidéosignaux. Application : évaluation quantitative automatique de chromatogrammes et analogues. |
