Abstract
A sample cell useful in analytical devices employing X-ray fluorescence as the detection method. The sample cell includes a cup which telescopically receives a ring. A radiation permeable membrane is sandwiched between the outside of the cup and the inside of the ring so as to be tightly stretched across the cup. The cup and ring are both molded from virgin polyethylene mixed with a silicone oil.
