Improving Hydraulic Fracturing Fluid Analysis Using the Kendrick Mass Defect
August 21st 2015The Kendrick mass defect combined with liquid chromatography quadrupole time-of-flight mass spectrometry (LC–QTOF-MS) can offer a variety of benefits to analysts investigating groundwater contamination. The Column spoke to Thomas Borch from Colorado State University in Colorado, USA, about his work in this area to find out more.
GC–MS Analysis of Laser‑Degraded Blue Tattoo Ink
August 21st 2015Laser irradiation of blue tattoo ink can create toxic byproducts - including hydrogen cyanide (HCN) - according to new research published by scientists at the German Federal Institute for Risk Assessment. Pyrolysis gas chromatography–mass spectrometry (Py–GC–MS) was performed on samples of copper phthalocyanine blue to predict the decomposition products resulting from irradiation, as part of a wider on-going project assessing the safety of tattoo inks.
