Given the wide range in polarity of the components of mesquite flour, it is advantageous to study the health benefits of this flour using methods that combine the complementary approaches of reversed-phase and aqueous normal phase LC.

LC–MS Characterization of Mesquite Flour Constituents

A new methodology for the analysis of three important -dicarbonyls (methylglyoxal, diacetyl, and pentane-2,3-dione) in wines was developed.

Determination of _α-Dicarbonyls in Wines Using Salting-Out Assisted Liquid–Liquid Extraction

Trace toxic and major nutrient elements were measured in a single measurement in a milk powder SRM, with no ionization buffers, using a synchronous dual view ICP-OES. The methodology was in accordance with Chinese method GB 5413.21 for raw milk and dairy products. Excellent recoveries were achieved for all elements determined in the SRM, demonstrating the accuracy of the method over a large dynamic range.
