Helium sample chamber for micro-XRF
For micro-focused X-ray fluorescence measurement of light elements such as sulfur, chlorine, potassium and calcium, sample chamber is purged with inert helium gas to reduce absorption by air. A sample chamber for helium purge is made from polylactic acid (PLA), plant-based thermoplastic polyester.
