The present invention provides a radiation detection system for detecting X-ray and gamma rays featuring CdMgTe in solid solution as a crystal semiconductor and electrical connection means. The crystal has a composition in the range of CdMgTe to CdMgTe and may be doped with indium or another Group III element, which may be suitable for use at room temperature as well as controlled temperatures. The present invention further provides a method for detecting X- or gamma ray radiation by (a) providing a solid solution CdMgTe crystal in the composition range of CdMgTe to CdMgTe; (b) providing an electrical contact means for connecting the CdMgTe crystal to an amplification, measurement, identification or imaging means; and (c) detecting the presence of the X- or gamma ray radiation.

Radiation detector

A sample card for use in a spectroscopic analytical instrument. The card is preferably disposable and includes an aperture through the card in which there is positioned a sample supporting window on which a sample is adapted to be placed. The sample supporting window is made from a light energy transmitting material by one of the steps such as cleaving, fly cutting, chipping milling, sawing or scaling. A method of manufacturing the card and for using the card are also included where the method includes the step of providing light supporting window by forming that window by the aforedescribed processes.

Sample holding substrate for use with an infrared spectrophotometer or filtometer and methods of manufacture and use thereof

Method and apparatus for forming thin films by the application of a film forming liquid to a substrate at rest or rotating a speed up to 500 rpm and then rotating the film forming liquid on the substrate at a speed and for a time sufficient to form the thin film. Such films can be used for analysis by spectrophotometric methods. Apparatus for forming such thin films is also disclosed.
