  • Systems for isolating toxins and collecting eluates for testing for toxins and methods using the same
    Patent number: 7655187
    Abstract: The present invention provides systems for isolating toxins and collecting an eluate from a sampling column for subsequent testing and to methods of extracting and collecting an eluate using the same systems. Preferably, the systems comprise a sample holder such as an immuno-affinity column for holding the sample and a self-contained fluid delivery system that can deliver liquid, e.g., reagents, and gaseous fluids, e.g., compressed air. More preferably, the fluid control system of the fluid delivery system provides some amount of pressurized gas continuously to the headspace of the column even when a fluid is not being forced through the resin gel in the column.

  • Method for determining the concentration of selected ingredients in animal feeds
    Patent number: 4421858
    Abstract: The present invention describes a method where, by using gentian violet as a tracer substance, the concentration of one or more selected components or factors of a complete animal feedstuff may be monitored throughout the life of the feed whether at the mill, in transit or at the place of its end use. In one embodiment, the method may be used to determine quickly whether any separation of components has occurred thereby destroying the homogeneity of the feedstuff and potentially endangering the animals to which the feedstuff is provided.
