Abstract: The present disclosure discusses a method of separating a sample (e.g., pharmaceutical drug, genotoxic impurity, biomarker, and/or biological metabolite) including coating a metallic flow path of a chromatographic system; injecting the sample into the chromatographic system; flowing the sample through the chromatographic system; separating the sample; and analyzing the separated sample using mass spectroscopy. In some examples, the coating applied to the surfaces defining the flow path is non-binding with respect to the sample—and the separated sample. Consequently, the sample does not bind to the low-binding surface of the coating of the flow path. The applied coating can increase the chromatographic peak area for the sample of the chromatographic system.

Abstract: A microelectromechanical device is provided. A vibrating structure gyroscope included in the device employs a temporal differential sensing method alone or a spatial differential sensing method in combination with the temporal differential sensing method. When used in combination, the temporal sensing method may be applied before the spatial sensing method or applied after the spatial sensing method. The temporal differential sensing samples signals at times t1 and t2 when velocity of a sensing mass within the vibrating structure gyroscope is maximum and has an opposite sign. The temporal sensing method improves Euler and Centrifugal forces cancellation and increases the signal to noise ratio if forces remain equal at times t1 and t2. Applying a high sampling speed can result in times t1 and t2 being sufficiently close to each other and therefore cancel any error terms associated with Euler and Centrifugal forces.

Abstract: Exemplary embodiments provide methods, mediums, and systems for creating a processing activity map for an analysis workflow in a chromatography experiment. A result set for the analysis workflow may be created and maintained throughout various stages of the analysis workflow. When certain trigger conditions are met, the in-use version of the result set may be persisted. For example, a read-only historical archive copy of the result set may be created, while the previous version of the result set is used in further stages of the analysis workflow. The trigger conditions may include a number of situations such as moving backwards in the workflow and making a change, moving across gated step boundaries in the analysis workflow, or receiving an instruction to clear the result set. The persistent, historical copies of the result set may be used to support auditing of a compliance-driven analysis process.
