Abstract
A method and apparatus comprising a companion cartridge containing a reagent storage system, a calibration fluid system, an assay element storage system, a carrier fluid system, and a waste retrieval system connected to a sensing cartridge to conduct chemical analysis. The companion cartridge can be adapted for assays related to blood chemistry, hematology, immuno-diagnostics, and DNA testing.
Claims20
A companion cartridge comprising at least one system chosen from reagent storage system, a calibration fluid system, an assay element preparation system, a carrier fluid system, and a waste retrieval system,
- said system connected to a sensing cartridge to conduct chemical analysis of at least one assay element.
A method of miniature chemical analysis comprising:
- at least one unit operation chosen from:
- storing at least one reagent on a companion cartridge;
- calibrating at least one sensor on a sensing cartridge with calibration fluid stored on said companion cartridge;
- preparing said at least one assay element for said assay;
- transporting said at least one of said assay elements with a carrier fluid;
- and
- retrieving waste from said assay
- wherein said sensing cartridge is in fluid contact with said companion cartridge.
An analytical instrument comprising:
- a companion cartridge comprising at least one unit operation chosen from a reagent storage system, a calibration fluid system, an assay element preparation system, a carrier fluid system, and a waste retrieval system;
- and
- a sensor cartridge, said sensor cartridge in fluid contact with said companion cartridge, wherein said sensor cartridge provides chemical analysis of at least one assay element.
A miniature analytical instrument comprising:
- a sensor cartridge for chemical analysis of at least one assay element adapted to fluid contact with a removable companion cartridge.
