WebThe deuterated compound behaves like the analyte and can be determined by mass spectrometry, monitoring a different ion. Once spiked, the sample should be allowed to equilibrate with gentle agitation for some hours, favoring the deuterated compound to be homogenized into the food. It is, therefore, necessary to previously reduce the particle ... WebDeuterated Monitoring Compound (DMC) Recovery VOCs: The following table summarizes DMC recoveries that failed the control limits.

WebHydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom, or vice versa. It can be applied most easily to exchangeable protons and deuterons, where such a transformation occurs in the presence of a suitable deuterium source, without any catalyst.
