  • Patent number: 11906489
    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.

  • Patent number: 11906479
    Abstract: A portable, case-enclosed pressure test manifold, configured to support both pneumatic and hydrostatic pressure testing, and comprising a downstream fluid path (e.g., a system test gauge, a ball valve, a system test port, a system relief valve, and other components/piping) and an upstream fluid path (e.g., a low-pressure gauge, a high-pressure gauge, and other components/piping). A regulator and/or the ball valve selectively operate the downstream fluid path, defining a hydrostatic pressure testing path, to receive a liquid; and the upstream fluid path in combination with the downstream fluid path, defining a pneumatic pressure testing path, to receive a gas. Manifold components are pressure rated based on use and are ASME Code B31.3 compliant. A flexible hose connects with either of the pneumatic pressure testing path and the hydrostatic pressure testing path of the manifold. The case includes parking receptables and a carrying handle configured to stow the hose during transport.
