Abstract

A structure being a modular system generally having a concentrator, separator, various detectors and a pump. The concentrator may have an array of phased heaters that are turned on at different times relative to each other in a fluid stream channel. The structure may relate to such a phased heater array structure, and more particularly to application of it relative to a sensor, analyzer or chromatograph for the identification and quantification of fluid components. The structure may be a miniaturized fluid micro system. The changeability of the modules of the system may be a plus for development, manufacturing, usage, repair and modification. It may also be energy-efficient, be battery-powered, and usable as a portable instrument.
