General description
Application
据报道也可作为提取混合物的成分用于GC-MS法筛查尿液中的滥用药物。
Features and Benefits
- 通过适用性测试，规定用于UHPLC-MS 和UHPLC-UV：分析灵活性
- 在正离子和负离子电喷雾离子化（ESI）和大气压化学电离-质谱（APCI-MS）中的规定质量，在所有重要MS模式（测试1）下实现分析物的最低检测限和置信度
—ESI/APCI (-) < 10 ppb
- 最低杂质含量：无干扰基线（测试2）
- 通过 0.2 μm过滤器进行微滤（测试3）以提供：
—减少柱堵塞的风险
- 硼硅酸盐玻璃瓶包装最大程度减少金属离子污染
- 最低水平的痕量金属杂质使金属离子含量最低
- UHPLC-MS 溶剂系列（PEG S/N 信噪比 < 50）中聚乙二醇（PEG）杂质含量最低

实验方案
The modern thin-layer chromatography (TLC) offers advantages also in the field of cosmetics to quickly and simultaneously analyze samples with densitometric detection.
Qualitative Thin Layer Chromatography Analysis of Flavonoids and Quantification of Terpene Lactones in Ginkgo Biloba Extracts and Tablets
Thin layer chromatography coupled with mass spectrometry does not require substantial sample preparation. Energy drinks can be applied without dilution directly onto the TLC plate.
商品
HPTLC separation followed by UV detection of the bitter acid content in various hop samples.
