WebSilver metal membrane filters are used in a variety of filtration applications, and their ability to withstand extreme chemical and thermal stress makes them ideal laboratory filtration … For example, a copper X-ray source may preferentially produce a beam of x-rays with wavelengths 154 and 139 picometres. Nickel has an absorption edge at 149 pm, between the two copper lines. Thus, using nickel as a filter for copper would result in the absorption of the slightly higher energy 139 pm x-rays, while letting the 154 pm rays through without a significant decrease in intensity. Thus, a copper X-ray source with a nickel filter can produce a nearly monochromati…
