Abstract: A sample cell assembly for use in a photometric analysis system has a heat conductive chamber structure enveloped by an electrothermal heating layer. The temperature of a sample inside the chamber is sensed by a temperature sensitive device mounted on the outside of the chamber structure to control the energization of the heating layer. A circulator with the chamber drives the sample in closed circulation paths within the chamber and uniformly distributes the heat transferred thereto from the heating layer through the chamber wall.

Abstract: A dispenser apparatus comprises a housing that includes a chamber for holding a sample. A member in the housing is moved relative to the chamber from a first position to a second position to aspirate material into the chamber and is moved from the second position to the first position to dispense material from the chamber. Pressure in the chamber is increased at the end of the dispensing movement to discharge all of the material from the chamber.

Abstract: An instrument system includes a sensor that has a logarithmic response, an antilog circuit and output means connected to the output of the antilog circuit to provide, as a linear function signals representative of the constituent sensed by the sensor. Balance adjust means for inserting a first compensating function in an additive manner to the signal from the sensor is connected in circuit between the sensor and antilog circuit and slope adjust means for inserting a second compensating function to change the slope characteristic of the signal applied to the antilog circuit is connected in circuit between the balance adjust means and the antilog circuit.
