Abstract: The present technology relates to a method of analyzing a sample including an analyte. The method includes injecting the sample including the analyte into a mobile phase. The mobile phase includes a metal chelator additive having a concentration between about 1 ppm to about 10 ppm. The method also includes separating the analyte using liquid chromatography and analyzing the analyte using a mass spectrometer, an ultra-violet detector, or a combination thereof.

Abstract: Medication dispensers and methods of dispensing medication are provided. A medication dispenser includes an exterior body defining an interior, and a distribution disk disposed within the interior, the distribution disk defining a plurality of compartments, the plurality of compartments disposed in at least one annular array, the distribution disk rotatably indexable about a central axis. The medication dispenser further includes a dispenser drawer in selective communication with one of the plurality of compartments disposed in the at least one annular array. The medication dispenser further includes a motor connected to the distribution disk, the motor operable to rotatably index the distribution disk about the central axis. Rotatable indexing of the distribution disk causes an adjustment in the one of the plurality of compartments disposed in the at least one annular array which is in communication with the dispenser drawer.

Abstract: A collator for assembling a packet from one or more sheets, includes a sheet collating tray, a retractable sheet stop within said sheet collating tray for stopping and aligning a leading edge of each sheet entering the sheet collating tray, thereby producing an aligned sheet packet, a movable sheet kicker for initiating output of the aligned sheet packet from the sheet collating tray, and sheet packet-grasping packet transfer belts for delivering from the collating tray each of the aligned sheet packets to downstream processing equipment. To optimize operational timing of the collator and for monitoring sheet progress through the collator, a programmed computer is provided that oversees for efficiency and possible errors sheet entry into the sheet collating tray, the presence of one or more sheets within the sheet collating tray, and the aligned sheet packet departure from the sheet collating tray.
