Abstract: A spark stand assembly for an optical emission spectroscopy includes: a spark stand body on a mounting flange enabling attaching the assembly to a main housing; an exciter in a recess on the body; an elevated portion on the body adjacent the mounting flange; an elongated notch on the body connecting the recess to a passageway through the elevated portion; a spark stand plate on the body to cover the recess, the notch and part of the elevated portion so the recess forms a plasma chamber and the notch forms a path to the passageway. The plate includes an opening exposing part of a sample on the opening for excitation, the opening being spatially aligned with the exciter when the plate is on the body; and a sealing member between the top of the body and the plate enclosing the recess and notch and routed over the elevated portion.

Abstract: According to an example, a spark stand assembly for an OES instrument is provided, the spark stand assembly including: a spark stand body that at least partially defines a plasma chamber; an exciter at least partially disposed inside the plasma chamber; and an optical transmission path from the plasma chamber for providing a view to a plasma generated in the plasma chamber, wherein the plasma chamber is provided with an opening for exposing a part of a sample positioned on the opening for excitation from the exciter so as to generate plasma on a surface of the sample upon activation of the exciter, and wherein a coating layer that includes a tribological coating is arranged to cover at least a portion of surfaces of the plasma chamber.

Abstract: The invention relates to an optical emission spectrometer (1) being easily adjustable, and to a method (100) to set-up and operate such a spectrometer (1) comprising a plasma stand (2) to establish a light emitting plasma from sample material, and an optical system (3) to measure the spectrum of the light (L) emitted by the plasma being characteristic to the sample material, where the optical system (3) comprises at least one light entrance aperture (31), at least one diffraction grating (32) to split up the light (L) coming from the plasma (A) and one or more detectors (33) to measure the spectrum of the light (L), wherein the plasma stand (2) and the optical system (3) are directly and fixedly mounted on respective a plasma stand flange (2B) and an optical system flange (3B) which are directly and fixedly connected to each other and wherein the optical emission spectrometer (1) further comprises an analyzing unit (34) adapted to analyze the measured spectrum and to compensate for a drift of the spectrum rel
