Abstract: The present disclosure provides for analysis systems that are configured to extract a fluid sample from a fluid (e.g., aqueous solution) in a reactor (e.g., bioreactor) at a first rate and then flow the fluid sample to a sensor system at a second rate to analyze the fluid sample. The sensor system can detect the presence and/or concentration of molecules (e.g., biomolecules such as biomarkers (e.g., metabolites, proteins, peptides, cytokines, growth factors, DNA, RNA, lipids) and cells of different types and cell properties, e.g., mechanical stiffness, etc.)). The data obtained can be used by a feedback control system to modify, as needed, the conditions in the reactor to enhance the productively of the reactor.

Abstract: A circulation device causes gas to circulate between a sample storage space and a temperature adjustment space through the first and second opening regions in a separating member.

The separating member further has first and second unit regions. The second opening region includes a first portion located in the first unit region and a second portion located in the second unit region. The shortest distance between the first portion and the first opening region is larger than the shortest distance between the second portion and the first opening region, and an aperture ratio of the first portion in the first unit region is larger than an aperture ratio of the second portion in the second unit region.

Abstract: A modified gathering manifold is disclosed, including a sampling header coupled to each of multiple production lines of wells, and a plurality of diverters, each coupled to one of the production lines, upstream of a relief header coupled to each of the plurality of production lines and a production header associated with the manifold and coupled to each of the plurality of production lines.

Abstract: Embodiments of the disclosure relate to chemical analysis systems, including autosampler systems. In some embodiments, an autosampler system can analyze gas phase samples using a single inlet for better consistency. The autosampler system can move the sample container closer to the sample introduction/preconcentration system prior to accessing the contents of the container to reduce exposure of the sample to reactive surfaces. The autosampler system is able to couple the sample containers to a sampling wand automatically, thereby eliminating the need to pre-attach each container using a gas transfer line. The autosampler system can be disposed on top of a chemical analysis system (e.g., a GC or GCMS), thereby conserving laboratory bench space. In some embodiments, the modules (e.g., sample trays, thermal conditioning systems, support legs) of the autosampler system can be coupled to the autosampler system using clamps that include magnetic codes associated with autocalibration information.
