Abstract: An assembly of two fiber optic ferrules allows for the mating of a CWDM fiber optic ferrule with a non-CWDM fiber optic ferrule. The CWDM fiber optic ferrule has optical fibers that carry optical beams with at least two different wavelengths, which the non-CWDM ferrule has optical fibers that carry only one wavelength. The CWDM fiber optic ferrule and the non-CWDM fiber optic ferrule have optical fibers that are inserted along parallel axes. The non-CWDM fiber optic ferrule has a lens pitch that matches the CWDM ferrule.

Abstract: A gas flow sensor receives a low-volume gas flow to be measured in a selectively sealed chamber. A flow rate signal is generated using a measuring device in response to the received gas flow. The flow rate signal is converted into a desired format for purposes of storage, control, and/or display.

Abstract: The present invention relates to a syringe including a barrel and a plunger. The barrel, the plunger, or both the barrel and the plunger can be made from or coated with a material that provides advantageous function and/or durability of these components. In certain embodiments, the barrel, the plunger, or both the barrel and the plunger can include or can be coated with a silicon material, such as silicon carbide or silicon oxide, or with a siloxane, such as a polymeric siloxane. In certain embodiments, the plunger can include or can be coated with a steel more durable than stainless steel. The invention also includes systems and methods employing such a syringe.

Abstract: Gas Chromatography (GC) sample introduction devices and methods for using the same are provided. Embodiments include septum retainer nut assemblies for use in GC inlet assemblies, fluid transfer member supports for introducing a fluid transfer member into a fluid transfer member guide of a septum retainer nut assembly of a GC device inlet assembly, and GC sample introduction systems. Also provided are methods of introducing a sample into a GC device, and kits for use in practicing the subject methods.
