1290 Infinity II 制备型开放式馏分收集器的性能特点 - 纯化组分的纯度及回收率
The Agilent 1290 Infinity II Preparative Open-Bed Fraction Collector was developed and optimized to enable efficient fraction collection with extended capacity and flexibility while providing the highest recovery and purity of the collected fractions. This Technical Overview demonstrates the performance of the 1290 Infinity II Preparative Open-Bed Fraction Collector when peak-based fraction collection is used. Using only the ultraviolet (UV) detection signal or a combination of UV and mass-selective detection (MSD) signals as a fraction trigger, purity and recovery of collected fractions are determined. Furthermore, the peak-based, collecting time slices fraction mode is discussed from a quantitative point of view.
