一般描述
该 Snap-N-Spike® 参考溶液适用于从临床毒理学到膳食补充剂测试的 LC/MS 或 GC/MS 应用。
咖啡因属于活性生物碱化合物，主要存在于约 63 种植物的叶子、果实和种子中。除了茶叶、巧克力和能量饮料之外，咖啡豆是咖啡因的主要来源。它是一种中枢神经系统兴奋剂，通过提高警觉性和减少睡眠来起作用。

应用
该认证标准物质（CRM）还可作如下用途：
- 采用傅里叶变换红外光谱-衰减全反射法（FTIR-ATR）和荧光分光光度法测定绿咖啡豆水溶液中咖啡因的含量
- 通过自动均相液-液微萃取法（A-HLLME）从 5 种不同的饮料样品中提取咖啡因，并结合高效液相色谱-紫外检测进行定量分析
- 通过紫外/可见光谱法同时测定咖啡中咖啡因和绿原酸
- 使用聚(4-氨基-3-羟基萘磺酸)修饰玻碳电极(聚(AHNSA)/GCE)方波伏安法对可口可乐、百事可乐和茶叶样品中咖啡因和对乙酰氨基酚进行多残留测定
- 基于循环伏安法和差分脉冲伏安法使用硫化锡(SnS)-二氧化钛(TiO2)-氧化石墨烯（GO）复合修饰玻碳电极上构建的电化学传感器分别和同时进行扑热息痛、色氨酸和咖啡因的检测和定量分析
