Connection element for spectral analysis
By designing connecting elements for the dilution gas inlet with an anti-surface line and the gradually narrowing downstream channel, the problems of fluid turbulence and matrix deposition were solved, improving transport efficiency, reducing deposition, and simplifying the analysis process.

AI Technical Summary
In existing technologies, connecting elements cause fluid flow turbulence, reducing transmission efficiency, and matrix deposits of high-matrix samples on the inner surface of the injector affect measurement results. Existing solutions, such as diluting the sample or reducing airflow, lead to longer analysis time or increased consumables.
Design a connecting element comprising downstream and upstream channel portions, providing dilution gas through a dilution gas inlet to reduce matrix deposition, the dilution gas inlet being axially opposite to the downstream channel, the downstream channel portion gradually tapering, the dilution gas acting as a sheath gas flowing around the sample fluid to reduce turbulence.
It improves the efficiency of sample fluid transfer, reduces matrix deposition on the inner surface of the injector, avoids turbulence and prolonged analysis time, and reduces the use of consumables.
