2. X-ray spectroscopy - Wikipedia

   en.wikipedia.org/wiki/X-ray_spectroscopy

   To maintain detector integrity and resolution it should be cooled with liquid nitrogen or by Peltier cooling. EDS is widely employed in electron microscopes (where imaging rather than spectroscopy is a main task) and in cheaper and/or portable XRF units. [citation needed] Bragg X-ray Spectrometer

   There are many models of Gold Purity Testing machines available - from portable (light weight) to industrial grade machines. Apart from X-ray spectrometer technique, other older traditional methods are using the TouchStone and Acid to test the gold purity. But TouchStone and Acid are destructive testing - a tiny sample of gold is cut and then ...

   An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.

6. Miniature mass spectrometer - Wikipedia

   en.wikipedia.org/wiki/Miniature_mass_spectrometer

   A miniature mass spectrometer (MMS) is a type of mass spectrometer (MS) which has small size and weight and can be understood as a portable or handheld device. What it means to be portable and a set of criteria by which portable and miniature mass spectrometers can be assessed have been discussed in detail. [ 1 ]

7. Spectrometer - Wikipedia

   en.wikipedia.org/wiki/Spectrometer

   An XPS spectrometer. A spectrometer (/ s p ɛ k ˈ t r ɒ m ɪ t ər /) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed.
