SPEX Speaker Archive

Behold The SPEX Speaker - the complete run of the unique trade journal that between 1956 and 1983, published articles, about a wide variety of spectrographic methods and techniques, while showcasing SPEX products. Art and Harriet Mitteldorf, who founded SPEX Industries, Inc. in 1954, started by selling graphite electrodes and spectrographic plates and film for arc/spark spectroscopy. They quickly developed their own analytical standards and sample preparation equipment, and those two traditions and product lines are proudly continued today by SPEX CertiPrep®, Inc., and SPEX® SamplePrep LLC.
