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.
