Abstract: The digital output of a spectrophotometer is multiplied by a factor to correct for drift in the absorbence of a sample standard. The value of the factor is determined by comparing a standard sample which has undergone drift against a preset value stored in the drift correction circuit. Circuitry is provided to accumulate the amount of drift correction and sound an alarm if it exceeds a predetermined value.

Abstract: The present invention is concerned with a spectrophotometer useful for determining light transmission of microsamples. It is particularly concerned with a spectrophotometer system using an improved microcuvette and extremely small optical elements for providing and acting upon the light beam that is used in determining the light-transmission characteristics of the sample. It is more particularly concerned with a double-cavity cuvette for receiving in one of the cavities of the cuvette a comparison or reference material and, in the other, the sample to be measured. Even more particularly it is concerned with a doublecavity micro-cuvette particularly adapted for utilizing a shifted-beam light system in which the beam is alternately refracted in different directions to direct it alternately through one cavity and then the other.
