Precious Metal Element Spectrometer

Precious metal element spectrometers are specialized instruments, such as XRF and OES analyzers, designed for precise, non-destructive elemental analysis of metals and alloys. Types of SpectrometersX-ray Fluorescence (XRF) Spectrometers XRF spectrometers are widely used for non-destructive analysis of precious metals like gold, silver, and platinum. They work by irradiating a sample with primary X-rays, causing the elements to emit characteristic secondary (fluorescent) X-rays.

These emissions are measured to determine the elemental composition.

F analyzers can be benchtop models, such as the SPECTRO MIDEX or VR-T6, or portable handheld devices like the JITAI9201, offering fast, accurate results with minimal sample preparation. Optical Emission Spectrometry (OES) OES, also known as spark OES, uses electrical sparks to ablate a metal surface, exciting atoms in an argon plasma. The emitted light is analyzed to quantify elemental concentrations.
