    摘要: A liquid chromatography system includes an autosampler with an injector valve by which a sample at low pressure within a sample loop is introduced into a high-pressure solvent mixture stream. A solvent delivery system includes a pump in fluidic communication with the injector valve of the autosampler to deliver the solvent mixture stream thereto. The solvent delivery system further comprises a processor that calculates a number of strokes of the pump needed to deliver the solvent mixture stream to the injector valve of the autosampler. The processor counts strokes of the pump during delivery of the solvent mixture stream. In response to a stroke count equaling the calculated number of strokes, the processor signals the autosampler to switch the injector valve to introduce the sample to the solvent mixture stream during a pump transfer period within which the pump performs pressure control to compensate for a drop in pressure.

    摘要: A liquid chromatography system includes an autosampler that prepares a sample for introduction to a solvent stream and a solvent delivery system that delivers a solvent stream to the autosampler. Delivery of the solvent stream occurs in parallel with the autosampler's pre-injection operations. The autosampler starts pre-injection operations to make the sample ready for injection into the mixture stream, and the solvent delivery system starts delivery of a solvent stream to the autosampler. The start of the solvent stream delivery is coordinated with the start of the pre-injection operations such that the solvent stream arrives at the autosampler approximately coincident with when the autosampler completes the pre-injection operations, making the sample ready for injection.

    摘要: Embodiments of the present invention are directed to a devices and methods for forming a desired miture of two or more fluids in a conduit. The devices and methods feature control means having error monitoring means and in response to an error event the control means organizes the packet-group of command signals to form at least one first error packet group. The error event occurs during the period of time in which the at least one error packet-group is received by a selectable value. The at least one error packet-group comprising an order or timing of first command signals and second commands signals to minimize deviation from the desired mixture in the flow of mixture-packets forming the desired mixture of two or more fluids in a conduit during the error event.

    摘要: Absolute quantitation of protein in a sample is provided by comparing a sum or average of the N highest ionization intensities observed for peptides of a particular protein along with a calibration standard. The calibration standard can be in the form of a table generated by prior protein peptide analysis performed using one or more pre-determined proteins. The comparison is used to determine a corresponding absolute quantity of protein based on the observed sum or average of ionization intensities. A simple conversion factor can be applied to the calibration standard value to determine the absolute quantity of protein in the sample.
