Product Authentication and Adulteration Determination Using a Novel Spectro-Electro Array Platform

Thermo Fisher Scientific has developed a gradient high-performance liquid chromatography (HPLC) method that uses a spectro-electro array platform to generate information-rich metabolic profiles that can be interrogated using chemometric modeling software. This application note demonstrates that this approach can be used to study product authenticity (differentiating wine varietals, orange juice varietals and growing region, and distinguishing tea blends) and adulteration (orange juice blending and inclusion of peel or pulp wash).
