Abstract

Abstract An automatic chemical analyzer which comprises a reaction line system (1) including a plurality of reaction lines (1 to 16) each consisting of a plurality of reaction tubes (1A) arranged in a row, means for distributing samples to the reaction tubes (lA), and means for carrying out chemical analysis of samples contained in the reaction tubes (1A). The reaction line system (1) is provided with a driving mechanism for driving the individual reaction lines intermittently and independently of one another, and is constructed to sure that the feed rate of the individual reaction lines can be freely changed. The automatic chemical analyzer can thus be reduced in size and nevertheless can quickly and reliably make analysis of a number of samples for a number of items.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 89 words
An automatic chemical analyzer comprising a reaction line system (1) including a plurality of reaction lines (1 to 16) arranged side by side and each consisting of a plurality of reaction tubes (lA) arranged in a row, means (3) for distributing samples to said reaction tubes (lA), and means for carrying out chemical analysis of the samples in said reaction tubes, characterized in that said reaction line system (1) further including a driving mechanism for driving and intermittently feeding said reaction lines (1 to 16) independently of one another.
Claim 2
Dependent Claim 89 words
An automatic chemical analyzer comprising a reaction line system (1) including a plurality of reaction lines (1 to 16) arranged side by side and each consisting of a plurality of reaction tubes (lA) arranged in a row, means (3) for distributing samples to said reaction tubes (lA), and means for carrying out chemical analysis of the samples in said reaction tubes, characterized in that said reaction line system (1) further including a driving mechanism for driving and intermittently feeding said reaction lines (1 to 16) independently of one another.
Claim 3
Dependent Claim 37 words
The automatic chemical analyzer according to claim 1, wherein said reaction line system includes a plurality of reaction line groups each including a plurality of reaction lines, said reaction groups being independently driven by said driving mechanism.
Claim 4
Dependent Claim 31 words
The automatic chemical analyzer according to claim 1 or 2, wherein the feed rate of said individual reaction lines or reaction line groups can be freely changed by said driving mechanism.
Claim 5
Dependent Claim 30 words
The automatic chemical analyzer according to claim 1 or 2, wherein said driving mechanism includes a plurality of endless chain conveyors for feeding said reaction lines or reaction line groups.
Claim 6
Dependent Claim 29 words
The automatic chemical analyzer according to claim 1 or 2, wherein said means for distributing said samples includes a plurality of nozzles and a mechanism for moving said nozzles.
Claim 7
Dependent Claim 35 words
The automatic chemical analyzer according to claim 5, which further comprises sample containers disposed adjacent to said reaction line system, samples contained in said sample containers being distributed to reaction tubes by said distributing means.
Claim 8
Dependent Claim 36 words
The automatic chemical analyzer according to claim 1 or 2, wherein said means for carrying out chemical analysis includes means for distributing a reagent to the reaction tubes containing samples and means for carrying out measurements.
