Analysis system

A chemical analysis system for analyzing a plurality of independent specimens that have time varying characteristics comprising:

• a plurality of analysis regions, each said analysis region adapted to hold a corresponding specimen,
• scanning means including a sensor for producing an analysis signal having a value proportional to a characteristic of the specimen in an analysis region, and means for causing sequential and repetitive sensing of said analysis regions by said sensor to produce analysis signals having values corresponding to the monitored specimen characteristics in the several analysis regions,
• memory means for storing data values in locations corresponding to the analysis regions from which these data values were provided,
• a signal transmission channel for applying data value signals to said memory means, said signal transmission channel including temporary signal storage means and variable response circuitry having a fast response mode and a slower response mode, and
• control means connected to said variable response circuitry and operative during a first portion of an analysis region sensing interval for concurrently placing said variable response circuitry in said fast response mode and connecting said memory means to the imput of said signal transmission channel to preset said temporary signal storage means to a data signal value from that analysis region that has been previously stored in said memory means,
• and operative during a second portion of said analysis region sensing interval for concurrently placing said variable response circuitry in said slower response mode and connecting said sensor to said signal transmission channel to adjust the data signal value in said temporary signal storage means to the current analysis signal value provided by said sensor, and
• means for transferring said adjusted data signal value from said temporary signal storage means to a location in said memory means corresponding to that analysis region.
