Abstract

Abstract @ Apparatus (10) for measuring or detecting a chemical entity in a liquid sample, the apparatus including a first module (12) operationally connected to a second module (14), the first module having a flow passage for the sample, the flow passage including a sensor (49) for measuring or detecting the chemical entity and pump means (34) for advancing the sample along the flow passage, the second module including means for actuating the pump means, and the second module being connected to the first module via connecting means permitting disconnection of the first and second modules and connection of a replacement first module to the second module.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 108 words
Apparatus (10) for measuring or detecting a chemical entity in a liquid sample, characterized in that said apparatus comprises a first module (12) operationally connected to a second module (14), said first module comprises a flow passage for said sample, said flow passage including a sensor (49) for measuring or detecting said chemical entity and pump means (34) for advancing said sample along said flow passage, said second module comprises means for actuating said pump means, and said second module is connected to said first module via connecting means permitting disconnection of said first and second modules and connection of a replacement first module to said second module.
Claim 2
Dependent Claim 108 words
Apparatus (10) for measuring or detecting a chemical entity in a liquid sample, characterized in that said apparatus comprises a first module (12) operationally connected to a second module (14), said first module comprises a flow passage for said sample, said flow passage including a sensor (49) for measuring or detecting said chemical entity and pump means (34) for advancing said sample along said flow passage, said second module comprises means for actuating said pump means, and said second module is connected to said first module via connecting means permitting disconnection of said first and second modules and connection of a replacement first module to said second module.
Claim 3
Dependent Claim 20 words
The apparatus of claim 1, characterized in that said sensor is capable of successively analyzing a plurality of said samples.
Claim 4
Dependent Claim 28 words
The apparatus of claim 1 characterized in that said first module comprises a plurality of different sensors for measuring a plurality of different chemical entities in said sample.
Claim 5
Dependent Claim 34 words
The apparatus of claim 1 characterized in that said flow passage of said first module includes, upstream from said sensor, a sample inlet port (18) for introducing said liquid sample into said first module.
Claim 6
Dependent Claim 17 words
The apparatus of claim 1 characterized in that said pump means is located downstream from said sensor.
Claim 7
Dependent Claim 49 words
The apparatus of claim 4 characterized in that said flow passage includes, downstream from said sample inlet port and upstream from said sensor, a selector valve (20) for controlling the intake of said sample into said flow passage, said selector valve being actuated by means in said second module.
Claim 8
Dependent Claim 47 words
The apparatus of claim 6 characterized in that said first module further comprises a holding chamber (28, 29) for holding a calibrating reagent, said holding chamber being connected to said flow passage, passage of said calibrating reagent into said flow passage being controlled by said selector valve.
Claim 9
Dependent Claim 17 words
The apparatus of claim 7 characterized in that second module includes means for actuating said selector valve.
Claim 10
Dependent Claim 36 words
The apparatus of claim 1 characterized in that said first module includes, downstream from said sensor, a waste chamber (26) for holding said sample after said chemical entity in said sample has been detected or measured.
Claim 11
Dependent Claim 55 words
A replaceable module for use in apparatus for measuring or detecting a chemical entity in a liquid sample, characterized in that said replaceable module comprises a flow passage for said sample, said flow passage including a sensor for measuring or detecting said chemical entity and pump means for advancing said sample along said flow passage.
Claim 12
Dependent Claim 55 words
A replaceable module for use in apparatus for measuring or detecting a chemical entity in a liquid sample, characterized in that said replaceable module comprises a flow passage for said sample, said flow passage including a sensor for measuring or detecting said chemical entity and pump means for advancing said sample along said flow passage.
