Specifications

Why Prolene?

Prolene is a preferred XRF window material because of its:

• Low elemental interference
• Excellent light-element transparency
• High chemical resistance
• Dimensional stability

Its superb transmission performance allows the CTX analyzers to maintain accuracy on elements such as Mg, Al, Si, P, S, Cl, K, Ca, and more.

Optional Add-Ons
