AN X-RAY ELEMENTAL ANALYZER: RUGGED, RAPID, REPEATED REAL TIME

Two nondestructive composition analyzers based on measuring the characteristic fluorescent X rays from test samples by means of solid state detectors are decribed and compared with other currently in-use industrial X-ray systems. The advantages of using solid-state dectors rather than diffracting crystal systems to measure characteristic X rays are reflected in the real-time high through-put analysis requirements of modern manufacturing operations. The two elemental X-ray analyzers described include a system to measure lead concentration directly from the rough cut surfaces of free machining steel samples. The lead analyzer is designed around a high purity geranium detector which measures the high energy K sub alpha X rays from the lead. Lead concentration is read from a lighted display in a matter of seconds following sample insertion. In the other systems described, the elemental composition of jet engine turbine blades is measured at a rate of several hundred blades per hour by a silicon X-ray detector. Blades that are not within compositional specifications are automatically rejected. For both systems described emphasis is placed on real-time analysis, simplicity of operation and minimal sample preparation. /Author/
