Abstract
Abstract An apparatus (1), magazine (2) and method are described for electrochemical detection or measurement. The apparatus (1) includes a magazine (2) with at least two separate cells (4), each cell (4) having analyzing means for measuring or detecting a component of a liquid sample, supplying means for supplying the liquid sample to each cell (4) in a sequential manner, advancing means for advancing the magazine (2) to position the supplying means at a next cell (4). The magazine (2) is advanced in a step wise motion such that a liquid sample can be supplied to each cell (4) in turn in sequence. The results of the analysis in the cells (4) is communicated to a processor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
66 words
An apparatus for electrochemical detection or
measurement of a component of a liquid comprising: a magazine having at least two separate cells; each
cell having analyzing means for measuring or detecting a
component of a liquid sample; supplying means for supplying
the liquid sample to each cell in a sequential manner;
advancing means for advancing the magazine to position the
supplying means at a next cell.
Claim 2
Dependent Claim
15 words
An apparatus as claimed in claim 1, wherein a
reagent is provided within each cell.
Claim 3
Dependent Claim
28 words
An apparatus as claimed in claim 1 or claim 2,
wherein the analyzing means is an electrode structure for
making measurements of one or more electrically measurable
characteristic.
Claim 4
Independent Claim
29 words
An apparatus as claimed in any one of claims 1 to 3,
wherein the magazine is in the form of a rotatable disc, a
strip, carousel, roll or film.
Claim 5
Independent Claim
42 words
An apparatus as claimed in any of claims 1 to 4,
wherein the cells are capillary fill cells and the means
for supplying the liquid sample to a cell is by contact of
the liquid sample with an opening to a cell.
Claim 6
Independent Claim
19 words
An apparatus as claimed in any of the preceding
claims, wherein the cells are separated by a liquid
barrier.
Claim 7
Dependent Claim
49 words
A magazine for electrochemical detection or
measurement of a component of a liquid comprising: at least two separate cells; each cell having
analyzing means for measuring or detecting a component of a
liquid sample; and each cell having an entrance for input
of a liquid sample into the cell.
Claim 8
Dependent Claim
14 words
A magazine as claimed in claim 7, wherein the
analyzing means is a reagent.
Claim 9
Dependent Claim
32 words
A magazine as claimed in claim 7 or claim 8, wherein
the analyzing means is an electrode structure for making
measurements of one or more electrically measurable
characteristics of the liquid sample.
Claim 10
Dependent Claim
20 words
A magazine as claimed in any of claims 7 to 9,
wherein the cells are separated by a liquid barrier.
Claim 11
Dependent Claim
31 words
A magazine as claimed in any of claims 7 to 10,
wherein the magazine is a disc, or is in the form of one of
a strip, carousel, roll or film.
Claim 12
Independent Claim
54 words
A method of electrochemical detection or measurement
of a component of a liquid comprising: supplying a liquid sample to a cell; analyzing the liquid sample by means for measuring
or detecting a component of the liquid sample; communicating the result of the analysis from the
cell; advancing to a subsequent cell; repeating the method.
Claim 13
Dependent Claim
26 words
A method as claimed in claim 12, wherein the liquid
sample is supplied to each cell by means of gravity or by
means of capillary action.
