WebJun 25, 2024 · Valérie Gabelica, Steven Daly, and Frédéric Rosu of the University of Bordeaux have now combined CD with mass spectrometry to overcome that problem (Science 2024, DOI: 10.1126/science.abb1822 ... WebBest choice for representative matrix for plant material. I run an Agilent 7900 for a compliance laboratory- love it, great machine, easy software. Right now to make my matrix spikes I use rosemary off the shelf for its ease of access and affordability. This stuff tends to have a fair amount of arsenic and lead in it, enough that I end up ...
