    摘要: A loop dilution system includes a dual-loop multi-way valve. In a first configuration of the multi-way valve, a first loop may be filled with a first solution and a second loop may be filled with a second solution. In a second configuration of the multi-way valve, the first and second loops are serially connected with a pump so that their contents may be mixed with a diluent. In another aspect of the invention, an in-process mass spectrometry (IPMS) system is disclosed that uses an internal standard to determine the concentration of an analyte in a sample. The internal standard has a different molecular composition than the analyte but is sufficiently similar chemically and physically to the analyte such that it behaves substantially the same as the analyte during an ionization process in the mass spectrometer.

    摘要: A system (50) includes a labeling machine (52) and a digital data processing system (54) connected to the labeling machine (52). A cutter (56) of the labeling machine (52) has a shaft (58) with a mark (60), which is sensed by a sensor (62). The sensor (62) supplies shaft (58) information on line (64) to digital data processing system (54). The digital data processing system (54) supplies control signals on line (64) to feed roll (66) stepper motor (67). The digital data processing means (54) is also connected to an optical sensor (76) by line (78). The optical sensor (76) senses the position of position mark (74) on the labels (70), which is correlated with the position of shaft (58) in order to feed the labels (70) to the cutter (56) at the proper rate so that the labels (70) are always cut at the kerf (72) between each label (70).
