Analysis system
First Claim
1. An analysis system for measuring a parameter of a fluid sample comprising:
- two metal heat sink members,a flow-through cell disposed between said heat sink members, said flow through cell having parallel opposed surfaces and each of said heat sink members having a surface in rating heat exchange contact with a corresponding one of said opposed cell surfaces,structure in said cell defining an inlet port, an outlet port, means defining a port capable of accepting a sensor, and means defining a flow path that serially connects said inlet port to said sensor accepting port and said sensor accepting port to said outlet port,a bore in one of said heat sink members,sample analysis electrode structure that has a sensor portion at one end thereof, said sample analysis electrode structure extending through said bore with said sensor portion disposed in sealing engagement in said sensor accepting port and forming a portion of the flow path so that sample material in said flow path contacts said sensor portion of said electrode structure,heater structure in physical contact with each said heat sink member,a temperature sensor in one of said heat sink members for sensing the temperature of said one heat sink member,preheater flow-through structure disposed in one of said heat sink members and connected to said inlet port for heating sample material being flowed to said flow-through cell for analysis, andflush solution flow-through structure physically supported in heat exchange relation with said heat sink members and connected to said outlet port path for stabilizing the temperature of flush solution to be flowed through said sample flow path.

Abstract
An analysis system for measuring a plurality of parameters of a fluid sample comprises a housing, and a flow-through cell in the housing that has opposed surfaces with at least two ports in each surface. One of the ports is an inlet port, a second of the ports is an outlet port, and at least two of the ports are sensing ports. A sample flow path including a serpentine portion in the cell serially connects the ports and extends from a port in one surface to a port in the other surface and back to a port in the one surface, and a sensor is disposed in sealing engagement with each sensing port and forms a portion of the serpentine flow path so that sample fluid to be analyzed contacts a surface of each sensor.
