Abstract
A micro fluid analyzer having a concentrator and separator. A strip continuous through a channel in the concentrator may provide a hot zone that may move with the flow of fluid through the channel of the concentrator to provide a concentration of heat in the flow. A pump may provide a flow to the fluid through the analyzer. Detectors may be positioned at places where the fluid may flow. A processor or controller may be connected to the strip, separator, pump and detectors. The concentrator, separator, detectors and processor may be integrated on one chip.
Claims14
A fluid analyzer comprising:
- a pump;
- a concentrator fluidly connected to the pump;
- and
- a separator fluidly connected to the concentrator;
- and
- wherein the concentrator comprises a channel and a continuous heater film along the channel;
- and
- a controller coupled to the continuous heater film for generating a moving heat pulse in the heater film that moves down the heater film and thus the channel, the moving heat pulse defined by a peak temperature with lower temperatures both downstream and upstream of the peak temperature.
A fluid analyzer, comprising:
- a channel for receiving a gas;
- a continuous heater film extending along at least part of the channel;
- a controller coupled to the heater film for generating a moving heat pulse that moves down the continuous heater film and thus the channel, the moving heat pulse defined by a peak temperature with lower temperatures both downstream and upstream of the peak temperature.
A method for operating a fluid analyzer having a channel, comprising:
- providing a gas down the channel, wherein the channel includes a continuous heater film extending along at least part of the channel;
- generating a moving heat pulse in the continuous heater film that translates down the continuous heater film and thus the channel, the moving heat pulse defined by a peak temperature with lower temperatures both downstream and upstream of the peak temperature.
A fluid analyzer, comprising:
- a channel for receiving a gas;
- a first heater element thermally coupled to the channel;
- a second heater element thermally coupled to the channel, wherein the second heater element is downstream of the first heater element and has a length along the channel that is less than the first heater element;
- a controller coupled to the first heater element and the second heater element, wherein the controller heats the first heater element, and a predetermined time later, heats the second heater element.
