Using simple constructional methods a special secondary collimator has been made from mica sheets and domestic aluminium foil which permits spectral images to be easily recorded (see Appendix). The collimator fits into the normal dual collimator tunnel of a commercial flat‐crystal spectrometer and instrument modification is unnecessary. A special film‐holding device ensures the spectral images are true to shape and size from the non‐focusing X‐ray spectrometer. Areas investigated range up to 0.9 inch 2 (6 cm 2 ) Imperial and metric equivalents, and measurements, throughout the paper are only approximate. and a small individual grain 0.001 inch 2 (1 mm 2 ) has been detected. Examples of specimen compositional differences, as well as variations in concentration levels, are given.
