Preparative SFC is a groundbreaking separation and purification technology. It has a number of advantages in comparison to preparative LC including simplified posttreatment, shorter analysis times, and different separation selectivity. With preparative SFC, the injection of large sample volumes is often required in order to increase the recovered amount.

The approach for the SFC analytical condition development process is basically the same as for determining analytical conditions for HPLC.

This issue focuses on "Forensics / Toxicology", an area where science and technology are particularly important and needed. It starts with two customer interviews.

The catechin analysis kit, developed in collaboration with the National Agriculture and Food Research Organization (NARO), provides validated test methods for catechins in tea leaves and green tea drinks from sample pre-treatment to HPLC measurement. You can accurately quantitate the content of 11 catechins (including methylated catechins) and caffeine in tea leaves. This article summarizes the results of the catechins quantitation in several beverages: green tea, black tea, and oolong tea.

This article describes a preparative online supercritical fluid extraction-supercritical fluid chromatography (SFE-SFC) system that combines an extraction step using supercritical carbon dioxide as the solvent, a separation step using supercritical carbon dioxide as the mobile phase, and a fractionation step using a preparative-scale fraction collector (FRC).

UF-Amino Station, which was developed in collaboration with Ajinomoto Co., Ltd., uses a special high-speed and high-separation column and the LCMS-2020 mass spectrometer, to perform batch analyses of 38* amino acids and amino acid-related components in a mere 9 minutes.
