TN209-01-基于Gilson VERITY®1900质谱引导的自动化馏分收集及再进样分析应用（英文）

INTRODUCTION
This technical note describes a simple plumbing scheme that allows optimization for both mass-directed collection of fractions, and subsequent automated reinjection of those fractions using off-the-shelf Gilson instrumentation. The dual system (prep and analytical) utilized a diode array detector and a VERITY® 1900 MS Detector (Figure 1 ). A 2-position, 10-port VALVEMATE® II was employed to switch the pump to the injector, the column to the detector, and to maintain the UV detector,
