Abstract
Abstract KNOWN ROTATING SPECTROPHOTOMETERS HAVE A SERIES OF CUVETS ARRANGED CONCENTRICALLY AROUND A HORIZONTALLY ROTATABLE DISC SO THAT THE DISC IS ROTATED, CENTRIFUGAL FORCE MIXES AND TRANSFERS REAGENTS AND SAMPLES TO THE CUVETS. AS EACH CUVET PASSES A LIGHT SOURCE, THE ABSORBANCE OF EACH INDIVIDUAL SAMPLE IS DETECTED AND MEASURED PHOTOMETRICALLY AND AN ELECTRICAL SIGNAL PROVIDED WHICH IS INDICATIVE OF THE EXTENT OF REACTION BETWEEN REAGENT AND SAMPLE. TO OBTAIN AN ACCURATE MEASUREMENT OF THE EXTENT OF REACTION A REFERENCE ELECTRICAL SIGNAL IS REQUIRED. THIS IS PROVIDED IN THE PRESENT INVENTION BY ROTATING THE CUVET CONTAINING DISC AT A SPEED SUCH THAT AN INITIAL ELECTRICAL SIGNAL IS OBTAINED BEFORE THERE IS ANY SUBSTANTIAL REACTION BETWEEN REAGENT AND SAMPLE IN THE CUVETS.
