Some embodiments herein are directed to devices and methods for automatically starting a plasma utilizing a wand. In some embodiments, the wand may be used to start a plasma in a plasma torch such as, for example, a microwave plasma torch or an induction plasma torch, as discussed below. The wand may comprise an elongate, hollow wand member comprising a closed distal end, a proximal end, and one or more apertures extending from a hollow interior of the wand member to an exterior surface of the wand member; and an elongate wire member positioned within the hollow interior of the wand member and extending along at least a portion of a length of the wand member, wherein the wire member is configured to be placed in operable communication through the aperture with a power source, such that the power source can be activated to in turn start the plasma within the plasma torch. The plasma torches discussed herein may be used in various applications including, for example, high volume synthesis of advanced materials such as nano-materials, micro-powders, coatings, alloy compositions for additive manufacturing.

Systems, devices, and methods for starting plasma

An apparatus for providing material feedstock into a plasma of a plasma torch includes a material feeding device having an input end and an output end. The output end of the material feeding device extends at least partially around the periphery of a plasma generated near the output end of the plasma torch. The material feeding device is oriented at an angle with respect to a central axis of the plasma torch.

Method and apparatus for feeding material into a plasma

A variable fluidic restrictor of a liquid chromatography system including a stator body, the stator body include a plurality of fluidic channels located within the stator body, wherein each fluidic channel of the plurality of fluidic channels includes a restrictor element, wherein a flow of a fluid through the variable fluidic restrictor is selectively restricted based on a position of an external element coupled to the stator body is provided. Furthermore, an associated method is also provided.

Variable fluidic restrictor having selective restriction

A diaphragm pressure transducer includes a body having an outer surface and a diaphragm, a strain gauge including a resistive element located on the outer surface, a fluidic inlet, and a fluidic cavity enclosed by the body in fluidic communication with the fluidic inlet, the fluidic cavity having an upper surface. The diaphragm is located between the upper surface of the fluidic cavity and the outer surface of the body. The diaphragm includes a variable thickness across a region defined between the upper surface of the fluidic cavity and the outer surface located below the strain gauge.
