1. A fluid analyzer comprising:
- a pre-concentrator having a plurality of parallel channels, the channels having an adsorbing film length of less then 1.0 cm;
a concentrator connected to the pre-concentrator;
a first separator connected to the concentrator; and
a controller connected to the pre-concentrator, the concentrator, and the first separator, the controller configured to activate and de-activate the pre-concentrator, concentrator, and first separator independently.

Abstract
A micro fluid analyzer having a concentrator and two or more separators. The analyzer may have one, two or more pumps. The analyzer may have a hyper pre-concentrator having a number of channels. There are numerous detectors positioned along the flow path of the analyzer. Also, one or more orifices and micro valves may be positioned in the flow path. The concentrator may have an array of phased heater elements that provide a heat pulse that moves along the fluid path to provide an increasing concentration of heat. The analyzer may be configured as a multiple fluid or gas chromatograph.

7. A fluid analyzer comprising:
-
a pre-concentrator having a plurality of parallel channels; a concentrator connected to the pre-concentrator; a first separator connected to the concentrator; a first plurality of heater elements in the channels of the pre-concentrator; and a controller connected to the heater elements, the controller configured to energize the heater elements in a time phased sequence such that each of the plurality of heater elements becomes heated and desorbs selected constituents into a sample fluid stream at about a time when an upstream concentration pulse, produced by one or more upstream heater elements, reaches the heater element, providing a concentrated heat pulse. - View Dependent Claims (8, 9, 10, 11)
