Abstract
The present invention contemplates an arrangement for analyzing a plurality of components in a single specimen which comprises placing a diluted specimen into a storage cup which is part of a sample carrier system, containing storage and reaction cups, transferring aliquots of the diluted solutions of the sample from the storage to the reaction cups, presenting the rows of the reaction cups to a work station, sequentially, adding a reagent to each of the reaction cups and moving the reaction cups into a work field where beams of light passing through the various reaction cups can be scanned and the components contained in the reaction cups can be assayed by means of a single detector attached to a computer and print-out system.
Claims15
In an analytical chemical system, an instrument for rapidly analyzing a plurality of components in a single specimen by the measurement of the light intensity emitted from a plurality of solutions using a single detector and light source, so as to translate these light intensities in terms of concentration of chemical components in these solutions, comprising
- a. a carrier and travel means, said carrier having a plurality of sample containers in rows thereon disposed to carry said containers which are to hold a specimen along a travel path by said travel means;
- b. a work station along said travel path having a light source thereat;
- c. light collimating means at said work station for collimating the light emitted from said light source to produce a first beam of the same color as said emitted light;
- d. light selection means disposed for receiving said first beam, for selecting a monochromatic beam of light from said collimated light source to produce a second beam;
- e. light isolating means for isolating a plurality of narrow third light beams from said collimated monochromatic second beam so disposed as to pass each of these third light beams in a plane through solutions in said plurality of containers so that part of the light is absorbed by samples therein and part transmitted;
- f. detector means and focusing means for focusing said transmitted third light beams so as to converge said third light beams to said detector means;
- g. interruption scanning means for scanning each of said transmitted third light beams emerging from said solutions sequentially so that said detector means receives said narrow light beams in sequence, said interruption scanning means comprising a disk rotatable about an axis, said disk having a plurality of holes at different radii from the axis of rotation of said disk, each disk positioned to interrupt said transmitted third light beams substantially perpendicular to the plane defined by said transmitted third light beams, wherein said disc sequentially scans a row of sample containers by rotating said disk with respect to said transmitted third light beams;
- and
- h. light reading means for translating the signals of the detector to a written record.
