Abstract
Isopotential heaters used in the preconcentration stage of sample detection systems are described. The heaters have at least two electrically conducting paths of which the resistances of the electrically conducting baths are substantially equal such that in use uniform heat distribution is achieved.
Claims32
An isopotential heater suitable for use in a preconcentrator, wherein said heater comprises at least two electrically conducting paths, wherein the electrical resistances of the at least two electrically conducting paths are substantially equal, such that in use, a uniform heat distribution is achieved.
A micro machined heater suitable for use in a preconcentrator, wherein said heater has an isopotential configuration, such that the electrical resistance of all paths through said configuration are substantially equal, such that in use, a uniform heat distribution is achieved.
