US 2026/0235552 A1 · METHODS AND SYSTEMS FOR DOPANT-ASSISTED SPECTROMETRY

Abstract

A technique for detecting an analyte in a sample may include contacting the sample with at least one dopant. The sample includes the analyte. The at least one dopant includes a compound of Chemical Formula 1: where E is independently phosphorus (P), sulfur(S), or arsenic (As), where Y′ and Y″ are each independently a chemical species or a lone pair of electrons, and where R1 and R2 are each independently selected from hydrogen, an alkyl group, an aryl group, a substituted alkyl group, or a substituted aryl group. The technique may further include forming an adduct ion from the analyte and the at least one dopant. The technique may further include performing spectrometric analysis of the adduct ion. The technique may further include determining, based on the spectrometric analysis, the analyte.
