Abstract
The invention discloses methods and devices for rapidly detecting a biological or other residue in a liquid sample. In some embodiments of the instant invention, a single electrode is employed to contact a flowing aqueous solution, with electrical outputs being recorded by an electrical metering device. Injection or flow of sample leads to changes in solution electrostatic behavior; those changes are recorded in the metering device, with absence of predetermined residues or targets yielding the highest signals. General and specific target detection may be performed with various embodiments of the instant invention.
Claims5
A device for identifying the presence of a biological or chemical residue in a liquid sample, consisting essentially of:
- a liquid delivery element;
- a single electrode disposed in non-contact proximity of 20 centimeters or less to said liquid delivery element,
- an electrical meter adapted to be in electrical communication with said single electrode through the agency of a single electrical terminal;
- and,
- a controller element programmed to receive readings from said meter, and further programmed to compare said readings to predetermined electrical reading values, determine presence of a biological or chemical residue and provide a signal to a user as to a presence of said chemical or biological residue in said liquid sample.
