Abstract: A method for clinical analysis is provided by combining a reagent with a sample composition and causing an enzymatic reaction thereof, projecting a light beam at the composition as the reaction progresses, providing a first electrical signal which is proportional to the absorbance of light by the composition, providing a second electrical signal which is substantially proportional to the first derivative of the first absorbance signal, continuously averaging the second signal for a predetermined interval of time, and coupling the second signal to an indicating means for providing a continuous visible display representative of the rate of reaction.

Abstract: A temperature stabilized photometric instrument is provided comprising an instrumentation housing including a body having a wall segment and a light permeable passage formed in the segment, a photometric light source positioned outside of the housing and arranged for projecting a light beam through the passage to the interior of the housing, means for supporting a translucent vessel containing sample material for analysis in the path of the light beam within the interior of the housing and photodetecting means positioned within the housing for receiving light which is transmitted by the vessel and for providing an electrical signal representative of an optical characteristic of the sample material. The instrumentation housing is formed of a material exhibiting a relatively high thermal conductivity and is thermally insulated. A thermally diffusive structure is positioned between the sample vessel and photodetectors for reducing transient temperature changes accompanying a newly introduced sample. Proportional heat control means are provided for maintaining the temperature of the housing at a predetermined value.
