Liquid chromatographic methods are presented for the quantitative and confirmatory determination of crystal violet (CV; also known as gentian violet), leucocrystal violet (LCV), brilliant green (BG), and leucobrilliant green (LBG) in catfish. LCV and LBG were oxidized to the chromic CV and BG by reaction with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone, and(More)
cu Most risk analyses begin by considering the behavior of the lowest and most detailed level of all possible events that can be identified in the system under study. Next, risk estimates are made for each event-consequence relationship and aggregated upward to obtain a total risk estimate of the process under study. The aggregation process propagates the(More)
The objective of this study was to compare 2 methods for the determination of tilmicosin residues in bovine liver samples. Three laboratories participated in the comparison of the 2 methods. The first method was described in a New Animal Drug Application (NADA 140-929), and the second was a modification of that method in which hexane was substituted for(More)
Most approaches to the construction of high-speed computers and logic systems in the past have been first, to go from serial to parallel circuitry, and then to use faster and faster components to increase the operational speed of the circuitry. High-speed components have reached the state where we are not talking about switching times in the order of the(More)
