This training guide introduces the ABSCIEX 4500 QTRAP LC‑MS system, covering its structure, ion sources, and recommended parameter settings.
The document provides a basic application training for the ABSCIEX 4500 QTRAP liquid chromatography‑mass spectrometry system. It describes the overall system architecture, including the curtain plate, orifice, Qjet®, LINAC®, detector and other core components.
It also explains the three main ion source types—TurboIonSpray (ESI), Heated Nebulizer (APCI) and PhotoSpray (APPI)—and gives recommended operating parameters such as flow rates, curtain gas pressure, ion spray voltage and source temperatures for optimal performance. This manual is written in Chinese.
