使用TOF-MS和可选保留时间的精确质量数据库进行目标化合物筛选可提高生产力, Part 1: Unique Capabilities of Agilent Software
This document describes the unique capabilities of Agilent software for increasing productivity in target compound screening using time-of-flight (TOF) mass spectrometry. It highlights the use of Accurate-Mass (AM) and Accurate-Mass/Retention Time (AMRT) databases, known as Personal Compound Databases (PCDs), which can be searched from within Agilent MassHunter Qualitative Analysis, Mass Profiler, and Mass Profiler Professional.
| METLIN Personal Metabolite Database compounds | more than 23,000 |
|---|---|
| METLIN lipids for lipidomics studies | 8000 |
| MassHunter Personal Pesticide Database entries | over 1600 |
| MassHunter Personal Forensic and Toxicology Database entries | about 6700 |
They can be searched from within Agilent Personal Compound Database and Library (PCDL) software, Agilent MassHunter Qualitative Analysis, Mass Profiler, and Mass Profiler Professional.
Retention time provides significantly improved specificity and allows the clear distinction between isomers, enhancing confidence in results.
Yes, because the databases are personal and reside on a local computer, users can add proprietary compounds to customize them.
