Claims
- 1. A portable apparatus for measuring the electrochemical characteristics of a sample, said apparatus comprising:
- a shell housing a cartridge bay configured so as to receive a plurality of cartridges from a clip;
- spring loaded means for advancing one of the cartridges into a measurement position within said shell;
- measuring structure means for measuring an electrochemical characteristic of a sample;
- means for in situ, automatic calibration of the measuring structure means within the cartridge prior to introduction of the sample into the cartridge when said cartridge is in the measurement position;
- means for indicating the electrochemical characteristics of the sample as measured by and received from the measuring structure means; and
- means for ejecting the cartridge holding the sample from the shell after information corresponding to the electrical characteristics of the sample has been indicated.
- 2. The portable apparatus of claim 1 wherein the cartridge bay of said shell comprises a linear channel capable of receiving a single file row of cartridges.
- 3. The portable apparatus of claim 1 wherein said spring loaded means comprises a loaded spring in contact with and delivering a constant force to and driving an unused cartridge into measurement position upon ejection of a used cartridge.
- 4. A portable apparatus for measuring the electro-chemical characteristic of a sample, said apparatus comprising:
- a shell housing a linearly channeled cartridge bay having a first end at a measurement position and a second end, the cartridge bay configured so as to receive a single file row of cartridges from a clip;
- a loaded spring having a first end attached to said shell and a second end in contact with the cartridges in the second end of the cartridge bay, said spring delivering a force to the cartridges in the direction of the measurement position;
- measuring structure means for measuring an electrochemical characteristic of a sample;
- means for in situ, automatic calibration of said measuring structure means within the cartridge prior to introduction of the sample into the cartridge when said cartridge is in the measurement position;
- means for indicating the electro-chemical characteristics of the sample as measured by and received from the measuring structure means; and
- means for ejecting the cartridge holding the sample from the apparatus after information corresponding to the electrical characteristics of the sample has been indicated.
