Abstract
A method and system for enabling the determination of kinetic rates within a fluid of interest including directing fluid flow exiting a test bed to a multi-port switching valve. The multi-port switching valve to switches the fluid to a number of channels connected to in in-flow extraction cartridge. Analytes of interest from the fluid flow our concentrated and captured on an extraction medium. Rates are determined by (i) sequentially channeling the fluid through the each of the plurality of channels for a preselected time duration, (ii) analyzing the extraction cartridges, and computing the kinetic rate of interest.
Claims19
A method for enabling the determination of kinetic rates within a fluid of interest comprising:
- directing fluid flow exiting a test bed to a multi-port switching valve;
- controlling the multi-port switching valve to switch the fluid to a plurality of channels;
- connecting each of the plurality of channels to at least one in-flow extraction cartridge;
- concentrating analytes of interest from the fluid flow;
- and
- capturing the analytes of interest on at least one extraction medium;
- and
- determining rates by (i) sequentially channeling the fluid through the each of the plurality of channels for a preselected time duration and (ii) analyzing the extraction cartridges, and computing the kinetic rate of interest.
A system for enabling the determination of kinetic rates within a fluid of interest comprising:
- a conduit for directing fluid flow exiting a test bed to a multi-port switching valve;
- a controller coupled to the multi-port switching valve to control switching the fluid to each of a plurality of channels for a preselected time duration;
- wherein each of the plurality of channels is coupled to at least one in-flow extraction cartridge having at least one extraction medium for concentrating analytes of interest from the fluid flow to capture the analytes of interest on the at least one extraction medium;
- and
- a processor for determining rates by (i) sequentially channeling the fluid through the extraction flow paths, (ii) analyzing the extraction cartridges, and (iii) computing the kinetic rate of interest.
