The present invention is an apparatus for laboratory and field use in detecting and measuring Hg and Hg in sample. A selective mercury binding agent, such as a chelating agent or clathrating agent, is covalently bound in a copolymer and deposited as an electrode layer. To prepare the preferred apparatus of the invention, thiophene, or other, similar monomer, is derivatized by covalent attachment thereto of Kryptofix-21â (1,4,10-trioxa-7,13-diazacyclopentadecane) in the 3-position. The thiophene monomer and Kryptofix-21â are co-polymerized and electrodeposited by known techniques onto a conductive substrate, such as platinum or glassy carbon, to obtain a multi-layer polymer coating of desired thickness. The resulting coated electrode has selective coordination sites for mercury of the order of K =10 , compared to K =10 for cadmium, K =10 for lead and K =10 for silver. Therefore, the resulting probe is very selective for mercury, compared to cadmium, lead and silver.

The present invention is an apparatus and a process for separation and resolution of particles suspended in, or molecules dissolved in, a sample mixture or solution using electrical field flow fractionation (EFFF). Fractionation of individual components in the mixture/solution is obtained by the interaction of particles/molecules with an electric field applied perpendicular to the flow direction, and externally to the fractionation channel. The plate electrodes are electrically isolated from the sample and carrier within a thin, non-permeable, insulating coating on the inside surfaces electrodes. This coating forms a barrier between the solution phase and the electric circuit used to generate the working electric field. The flow channel is formed by sandwiching a shaped insulating gasket between the two parallel plate electrodes. The side walls of the channel are defined then by the inside walls of the shaped, insulating gasket.

A method of electrochemical deposition uses microdroplets of electrolytic solution over a targeted small circuit element. Only the targeted circuit element is electrically biased so that deposition occurs on the surface of that element, underneath the microdroplet, and nowhere else unless it is under other microdroplet(s). The invented method achieves extremely accurate and selective electrochemical deposition with a tiny amount of electrolytic solution, compared to conventional submersive and/or immersive methods, and eliminates the need for masking or etching, reducing the costs of manufacture and amount of waste electrolytic solution produced.

An apparatus may be adaptable for laboratory, field, or in vivo detection and measurement of benzene, benzenoids, or other organic molecules or compounds. A selective binding agent is created by binding a target molecule or similar molecule with an appropriate monomer, polymerizing the monomer, and removing the target or similar molecule. This procedure results in binding agent sites that are highly selective for the target molecule over other similar organic molecules. The finished binding agent is coated onto or otherwise incorporated with an electrode. The size of the electrode diameter may range from a scale of inches to a scale of sub micrometers, depending on the application. In preferred embodiments, polymers templated with a derivatized benzene molecule have shown to be effective even for detection and measurement of benzene, which is non-electroreactive. Benzene in a solution to which the templated polymer is exposed surprisingly results in increased conductivity of the polymer, with the conductivity increasing with increased benzene concentration in the solution.

An actinyl-selective polymer detects the presence of actinide ions in a solution. An electrode or FET gate surface of a sensor element may be coated or otherwise made to include the actinyl-selective polymer, which preferably includes chelating molecules selective to ions having the general formula MO, where M represents any metal in the actinide group and X represents 1+, 2+, or any other charge state, including uranium ions (UO), plutonium ions (PuO, PuO), and thorium ions (ThO) and others. The chelating polymer is preferably made by first polymerizing a selected monomer and then derivatizing the polymer with a calix[n]arene rings (where n=4-10) compound, resulting in a high density of chelating molecules on the surface of the polymer, where they are accessible to the solutions being testing and cleansing or rejuvenating solutions.

The invention is a positive charge director for liquid electrographic toners. The charge director comprises a very strongly chelating functional group covalently bonded in the resin coating or pigment component, or an intrinsic part of the pigment component, of the toner particle, and a very weakly associated, preferably ionic, molecule dispersed in the liquid phase to achieve charge separation. The strong chelation site on the resin is prepared, via well-known polymer chemistry. For the ionic molecule, preferred cations are those with no regulatory, health or environmental issues, such as K+, Na+, Ca. sup. 2+, Al. sup. 3+, Zn. sup. 2+, Zr. sup. 4+, Mg. sup. 2+, ammonium (NH. sub. 4 +), and organic cations. The chelate-containing resin is brought into dispersion with the liquid phase containing the ionic molecule. When this is done, the equilibria that compete for the cation are such that it is released from the ionic molecule and bound in the chelate.

This invention consolidates all of the functions served by the EP toner in one macromolecule. The invention is a macromolecule of dye-polymer comprising a dye colorant copolymerized with a linking/spacing component, using well known principles of polymer chemistry. A dye/charge director component may be copolymerized with the dye colorant and the linking/spacing component simultaneously or subsequently, or it may be an intrinsic part of the dye colorant or the linking/spacing component.
