前言:
Thermo Scientific TraceFinder software includes built-in workflows for streamlining routine analyses in environmental and food safety laboratories. By incorporating a database of liquid chromatography-mass spectrometry (LC/MS) methods that can be customized to include unique compounds, TraceFinder™ allows the analyst to access commonly encountered contaminants found in the environment. To demonstrate the capabilities of this software, a mixture of triazine compounds spiked into drinking water samples was analyzed. Using direct injections of 20 mL samples (with on-line preconcentration), low- and sub-pg/mL (ppt) levels were detected. The ability to analyze these drinking water samples with on-line preconcentration saves considerable time and expense compared to solid phase extraction techniques.

Thermo Scientific TSQ Quantum mass spectrometer
结论:
In this application note, TraceFinder software was used in conjunction with an online preconcentration system, Equan™, for the robust and reproducible analysis of large volumes of drinking water. Triazines were quantitated at the sub-ppt level, and several commercial bottled drinking water samples and one sugar-free soda sample were analyzed for the presence of triazines. Only one sample contained any traces of triazines: a commercial drinking water sample tested positive for atrazine. TraceFinder can also be used for traditional LC/MS applications, minimizing method development time. The method development capabilities and Compound Datastore of TraceFinder allowed for the quick creation of a method for the analysis of these compounds.
