儀器功能 & 測定項目
Liquid Chromatography-Mass Spectrometry (LC-MS)：
Waters micromass ZQ detector is a single quadrupole mass analyzer that can determine mass-to-charge ratio (m/z)
for low- resolution analysis. The mass-to-charge ratio (m/z) of ZQ mass detector can be up to 4,000 Da.
Waters 2695 Separations Module carried with C-18 column is used for separation.
The micromass ZQ detector can simultaneously record positive and negative ions produced by
electrospray ionization (ESI) mode. For LC-MS analysis working,
samples require to eliminate particles and salt matrix effect first.
LC-MS 定性鑑別：
1. 為電噴灑質譜儀 (ESI-MS)，可同時掃描m/z範圍4,000以下正、負離子(ESI+、ESI-)。
2. 小分子有機藥物、天然物低解析質譜定性鑑別，屬送測高解析質譜儀前必備之初步鑑別。
ESI-MS 直接質譜：
1. 分析樣品直接進入質譜儀，搜尋質譜分析。
