Abstract: An immunoassay method that integrates a sample processing component that enables the testing of a variety of environmental matrixes and the components for performing the method, wherein the immunoassay utilizes a monoclonal anti-petroleum antibody to detect the presence or absence of petroleum based contamination in a sample when tested in a field or laboratory location.

Abstract: An immunoassay method that integrates a sample processing component that enables the testing of a variety of environmental matrixes and the components for performing the method, wherein the immunoassay utilizes a monoclonal anti-PAH antibody to detect the presence or absence of PAH contamination in a sample when tested in a field or laboratory location.

Abstract: An immunoassay method that integrates a sample processing component that enables the testing of samples for the presence of an immunologically non-remarkable compound, such as benzene, by the use of a monoclonal antibody having specific reactivity for an immunologically remarkable compound, such as nitrobenzene, which has been prepared by reacting the immunologically non-remarkable compound with derivatizing agent, and the components for performing the method, wherein one example of the immunoassay utilizes a monoclonal anti-nitrobenzene antibody to detect the presence or absence of benzene contamination in an aqueous sample when tested in a field or laboratory location.

Abstract: An improved belted chain is described in which there are a plurality of pairs of chain rods secured to spaced-apart carriers and a central belt. The inner ends of the chain rods in each pair are aligned end-to-end with each other and then secured to the central belt. The outer ends are secured to the spaced-apart carriers. Preferably the central belt is composed of rubber. The chain rods in each pair are able to be flexed relative to each other without danger of breaking the rods.
