Abstract:
A chromatographic device (10) for analysing multiple samples comprises a separator (22) for separating the multiple samples, an injector unit (15) for injecting the multiple samples into the separator (22), the injector unit (15) being provided as regular injector unit for single-sample chromatography, a detector (24) for detecting signals of the multiple samples after they are separated by the separator (22), a sequence generator (12) for generating a specific binary sequence for each of the multiple samples, a controller (12) that controls the injector unit (15) so that each of the multiple samples is injected into the separator (22) in pulses corresponding to its specific binary sequence, and a decomposer (12) for decomposing the detected signals of the multiple samples by identifying the specific binary sequences in the detected signals.
Abstract:
Oral fluid for drug testing has several advantages over other specimens: (1) It may be collected noninvasively and under direct supervision; (2) its drug concentration reflects blood-drug concentrations; and (3) it can be processed by conventional drug screening and confirmation methods. This technology provides a system that measures the quantity of a drug (without needing a priori knowledge of the drug) in an oral fluid specimen and translates this level to a blood plasma drug concentration. The method first measures the concentration of a drug in an oral fluid sample. Next, a processor calculates the blood plasma concentration from the measured oral fluid drug concentration. Finally, this blood plasma drug level is utilized to calculate a total body drug concentration.
Abstract:
A drive module that includes an electric motor and a multi-speed transmission assembly having a two-speed planetary transmission stage. The multi-speed transmission assembly outputs rotary power to a differential assembly.
Abstract:
Detecting a definitive presence or absence of an analyte from a borderline test is shown and described. In one embodiment, a method of generating a definitive test result includes continuously incubating the assay concuiTently with continuously reading a diagnostic test on the assay. In particular examples, reading the diagnostic test on the assay includes performing a one minute diagnostic reading. Typically, when a borderline test result is detected, further development of the assay is performed. In most examples, detecting a definitive presence or absence test result deactivates the testing sequence.
Abstract:
A chromatographic separation device includes a chromatographic separation module and a memory component. The memory component is attached to the chromatographic separation module, contains information related to the chromatographic separation module with respect to the entire lifetime thereof, and includes a write-once-read-many (WORM) area where the information is written.
