| Description | Method scouting is a process where different mobile phases and column stationary phases are evaluated to determine the best set of separation conditions for a particular sample. Manual solvent preparation, column switching, and method programming are time-consuming steps, so the Nexera method Method scouting is a process where different mobile phases and column stationary phases are evaluated to determine the best set of separation conditions for a particular sample. Manual solvent preparation, column switching, and method programming are time-consuming steps, so the Nexera method scouting system was developed to streamline the entire process for more efficient method development.
The system is based around 2 LC-30AD pumps, each with a quaternary valve, which allows the analyst to run binary gradients with 16 different solvent pairs. A high-pressure column selection valve holds from 1 to 6 columns, resulting in up to 96 unique separation conditions per sample. Ultra-high speed conditions can be easily transferred to conventional conditions using a transfer program. In addition, scouting is performed automatically when the mobile phase is switched.
The Nexera Method Scouting Solution software has intuitive, user-friendly screens to set the pump and column valve positions, gradient program steps, and it automatically builds the sequence table in seconds. Method Scouting Solution provides the data required for analysis via a graphical user interface, as well as automated controls conforming to laboratory operations configured in the system settings.

This system uses detection by post-column fluorescence derivatization, with o-phthalaldehyde (OPA) / N-acetylcysteine as the reaction reagent, to selectively and with high sensitivity quantitate the amino acids contained in samples with high levels of contaminants.
Features - Selectively detects amino acids based on Shimadzu's highly acclaimed post-column reaction technology and high-sensitivity fluorescence detector.
Detects amino acids with over ten times higher sensitivity than the ninhydrin method (UV detection), by using a derivatization method that provides selective reaction with amino radicals, together with fluorescence detection. - Outstanding Reproducibility
Because derivatization occurs after separation in the column, reactions are not affected by the sample matrix. Therefore, analyses can be performed with good precision. - Easy to Operate
Since column eluant is automatically derivatized by mixing it with the reaction reagent, it saves time and tedious tasks. - The mobile phase and reaction solution are available as a kit, which means solutions can be prepared with minimal fuss.
