Abstract: A furnace system features a combination of a furnace, a main combustion furnace tube and a disposable guard tube. The main combustion furnace tube is configured to couple and extend from the furnace, made of a quartz tube material, and has a zone for a combustion catalyst or high temperature support configured or formed therein. The disposable guard tube is coupled to the main combustion furnace tube, has a top opening configured to receive and have direct exposure to a liquid sample being injected into the main combustion furnace tube, and also has a bottom opening to provide the liquid sample to the main combustion furnace tube for processing in the zone for the combustion catalyst or high temperature support.

Abstract: A furnace system has a furnace-tube-cap (FTC) and a slider. The FTC has a first-cap-portion coupled to a furnace tube of a furnace, a second-cap-portion with a bearing-assembly-arrangement (BAA), and an inner-tube-cap-channel (ITCC) passing from the first-to-second cap portion with an ITCC sealing arrangement extending outside the ITCC. The slider slides in the BAA to/from inject-and-rinse positions, and has a first-ramp (FR), a first-raised-surface (FRS), an intermediate-lower-surface (ILS), a second-ramp (SR), and a second-raised-surface (SRS). When the slider moves to the inject-or-rinse positions, the BAA forces a slider-part to push against an inner-channel-sealing-arrangement (ICSA) as the BAA goes from the FR-to-FRS, or the SR-to-SRS. When the slider is in the inject-or-rinse position, a first-slider-part seals the ITCC sealing arrangement.

Abstract: According to some embodiments, the present invention may include, or take the form of, a total organic carbon analyzer, featuring an injector, a reactor, condensation components and two three-way valves. The injector may be configured to provide a sample. The reactor may be configured to vaporize the sample received. The condensation components may be configured to condense and trap the sample vaporized by the reactor. The two three-way valves may be arranged between the reactor and the condensation components and configured to allow flow to either bypass or pass through the reactor and the condensation components, while in the bypass mode, the sample being injected at an appropriate rate so as to allow the sample to condense at or near the same rate as the sample is being injected.

Abstract: A sliding style furnace cap features a furnace tube cap and a slider. The furnace tube cap has a first cap portion to couple to a furnace tube of a furnace, and a second cap portion with a bearing assembly arrangement. The furnace tube cap also has an inner tube cap channel passing through it with an inner tube cap channel sealing arrangement configured to extend outside the inner tube cap channel. The slider has an orifice/channel configured therein passing through the slider, couples and slides in the bearing assembly arrangement from an inject position to a rinse position, and vice versa, has a cam-like contoured surface with a first ramp configured to couple a first raised surface and an intermediate lower surface, and with a second ramp configured to couple the intermediate lower surface to a second raised surface.

Abstract: An improved reaction tube having an interior configured for bifurcated chambers. The present device has an inert chamber and a catalyst chamber where the materials contained therein are decoupled from one another. This improved tube is especially beneficial as it provides for greater working efficiency, preservation of catalytic materials, straightforward maintenance and replacement procedures, and effective isolation of unwanted particles.
