Consists of a sensor electrode (implanted or disposable) that measures glucose concentration in the interstitial fluid, and a receiver device where the measurements are sent through by a transmitter to be displayed. To automatically measure glucose at regular intervals (e.g. every 5–15 minutes).
Beckman Coulter, Inc. is a Danaher Corporation company that develops, manufactures, and markets products relevant to biomedical testing. It operates in the industries of diagnostics and life sciences .
Flow cytometry (FC) is a technique used to detect and measure the physical and chemical characteristics of a population of cells or particles. [1] [2] [3] [4]In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument.
Hydrodynamic focusing solves this problem by building up the walls of the tunnel from fluid, using the effects of fluid dynamics. A wide (hundreds of micrometers in diameter) tube made of glass or plastic is used, through which a "wall" of fluid called the sheath flow is pumped. The sample is injected into the middle of the sheath flow.
A Coulter counter [1] [2] is an apparatus for counting and sizing particles suspended in electrolytes. The Coulter counter is the commercial term for the technique known as resistive pulse sensing or electrical zone sensing.
