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.

Catalyst guard

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. When the slider transitions between the inject-and-rinse positions and the BAA rides along the ILS, the BAA allows the slider-part to float above the ICSA arrangement.

Smart slide

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.
