September 13, 2016     Spectroscopy Spotlight Analysis for Lead in Laundered Shop Towels Using Handheld X-ray Fluorescence Spectroscopy The ability of portable handheld X-ray fluorescence spectroscopy to measure harmful contaminants, such as lead, in towels is tested. The New Standard in Microwave Digestion Two decades ago, CEM introduced the fiber optic probe. This changed the way scientists prepared samples. Now, with iWaveTM, we've done it again. iWave technology wirelessly measures the temperature of the sample inside each vessel delivering the accuracy of fiber optic probes without the need of a control vessel. This contactless, in-situ measurement provides for the best reaction control ever imagined in a microwave digestion system.
