The second edition of the SCP Science “Instruments & Supplies” catalog specifies new products for the inorganic chemical laboratory, including the PlasmaPure Plus high-purity acids, a variety of DigiSep solid-phase-extraction cartridges, and the high-volume DigiPrep LS metal digestion system (72-position) for agricultural and environmental applications. The 179-page resource itemizes supplies for sample preparation, atomic absorption, x-ray fluorescence, chemical oxygen demand, and inductively coupled plasma MS and atomic emission spectroscopy. It includes sections on calibration and quality control standards and on graphite products such as combustion crucibles. Charts, diagrams and indexes are provided.
