PEER-REVIEWED ARTICLE:
Trace Organic Analysis of Surface Water
In this study the orthogonality of SFC to the serial coupling of reversed-phase–HILIC is highlighted. It is shown that both techniques are highly orthogonal and complementary. The parallel use of the two techniques offers additional benefits for compound monitoring in complex samples. Read more >>
