Analysis of Kakkonto by Nexera-e and SPD-M30A Photodiode Array Detector (Part 2)

Kakkonto is a mixture of several traditional Chinese medicines. Type of compounds and their contained amount vary due to their origin. Here, we compared 2D contour plots of four kinds of kakkonto obtained by the Nexera-e comprehesive two-dimensional chromatograph.
The 2D analysis enables confirmation of comprehensive separation and profiling of complicated samples. It will be useful for quality control and help to narrow down target compounds for study by differential analysis.
