METHODS AND SYSTEMS FOR DETERMINING MULTI-COLUMN CHROMATOGRAPHY PROCESS CONFIGURATION

The disclosure generally relates to methods and systems for determining multi-column chromatography process configuration for capturing antibodies. Conventional approaches for design of MCC configuration are limited to rule based, either driven by UV spectroscopic measurements or by performing number of experiments, which involves a lot of material costs and time utilization. The present disclosure solves the technical problem of identifying the operational conditions that optimized the MCC process and the MCC configuration. A multi-objective optimization function defined with one or more decision variables associated with the operating conditions is considered to determine the optimal MCC configuration, while satisfying purification goals. The one or more key performance measures of the MCC process comprises a productivity, a capacity utilization, a product yield, and a product purity. The significant amount of time and the material cost invested for designing the optimum MCC configuration is decreased by the present disclosure.

Flow passage unit

A flow passage unit has a column for used in a liquid chromatograph and a support body that supports the column. The column has: a porous stationary phase; a porous pressure adjusting part disposed at least at the flow-in end of the stationary phase, a liquid entering the flow-in end, the pressure adjusting part being harder than the stationary phase; and a covering part that covers the stationary phase and pressure adjusting part. The support body has a first plate and a second plate that are mutually joined, the support body forming a column holding part and a liquid flow passage, the column holding part holding the column between the first plate and the second plate, the liquid flow passage communicating with the column holding part. Pressure applied from the first plate and second plate to the pressure adjusting part is higher than pressure applied to the stationary phase.

METHOD FOR SEPARATION WITH SIMULATED MOVING BED

20210232675 · 2021-07-29 ·

Examples of the present disclosure describe systems and methods for detecting and mitigating stack pivoting exploits. In aspects, various “checkpoints” may be identified in software code. At each checkpoint, the current stack pointer, stack base, and stack limit for each mode of execution may be obtained. The current stack pointer for each mode of execution may be evaluated to determine whether the stack pointer falls within a stack range between the stack base and the stack limit of the respective mode of execution. When the stack pointer is determined to be outside of the expected stack range, a stack pivot exploit is detected and one or more remedial actions may be automatically performed.
