DEVICE AND METHOD FOR THE PREPARATION OF A CONTROL SOLUTION FOR KETONE DETERMINATION AND METHOD OF CALIBRATING A KETONE TEST INSTRUMENT

摘要

A device for preparing a control solution for ketone analysis is disclosed, as well as a method for preparing it. The device comprises a carrier vehicle incorporated with an ester of a beta -ketoalkanoic acid, and a hydrolyzing substance capable of converting the ester to the corresponding beta -ketoalkanoic acid. The ester has the structure R min -@-CH2-@-OR in which R is a lower alkyl group and R min is an aliphatic or cyclic group having 1 to about 7 carbon atoms. The method comprises contacting a predetermined volume of solvent with the device.
