Analytical method and apparatus using chemical analytical slides
First Claim
1. A method of automatically dispensing samples onto chemical analytical slides in an automatic analytical analyzer comprising the steps of:
- placing liquid samples in an automatic sampler of an analyzer;
arranging chemical analytical slides by groups according to respective analyzes to be measured for each of said samples;
interposing a partition plate which is optically discriminable from said chemical analytical slides between adjacent ones of said groups of said chemical analytical slides;
loading said chemical analytical slides and said partition plate in said analyzer;
automatically moving said groups of said chemical analytical slides and said partition plate along a path through a dispensing station to a chemical analyzer;
dispensing a first one of said samples onto a first one of said groups of chemical analytical slides at said dispensing station;
detecting the presence of said partition plate between said groups of said chemical analytical slides in said path; and
in response to the detection of said partition plate, immediately dispensing a second one of said samples onto a next adjacent group of chemical analytical slides at said dispensing station.

Abstract
An analytical method using chemical analytical slides which includes the steps of: placing liquid samples in an automatic sampler of an analyzer, loading in to said analyzer the chemical analytical slides combined in groups according to respective analytes to be measured in each sample, including a partition plate interposed between said groups of the chemical analytical slides, and changing over the sample to be spotted on the chemical analytical slide by means of said automatic sampler when said partition plate is detected.
By employing this method, the sample to be spotted can be precisely and synchronously changed, and therefore, serious error is prevented that might occur if the analytical result of a different person is used to distinguish between analytes. Moreover, the analytical operation is simple and highly efficient.

11. An automatic dispensing apparatus for an analytical analyzer comprising:
-
means for storing a plurality of chemical analytical slides and a partition plate, said plurality of chemical analytical slides being arranged in groups and said partition plate dividing adjacent groups of chemical analytical slides, wherein said partition plate is optically discriminable; means for storing a plurality of samples; means for automatically moving said chemical analytical slides and said partition plate through a dispensing station to a chemical analyzer; means for selectively dispensing said samples onto respective groups of said chemical analytical slides at said dispensing station; means for detecting the presence of said partition plate dividing adjacent groups of chemical analytical slides; and means, responsive to an output signal from said detecting means representing a detection of said partition plate, for moving one of said samples into said dispensing station so that said one of said samples is immediately dispensed onto its respective group of chemical analytical slides. - View Dependent Claims (12, 13, 14, 15)
