一般描述
油酸是一种长链不饱和脂肪酸,在 C9 和 C10 之间有一个顺式配置双键。它是最常见的脂肪酸,在一定程度上存在于大多数油和脂肪中。
这种物质被列入EU第10/2011号法规中用于与食品接触的塑料的正面清单。请点击此处查看列入10/2011 的所有化合物的参考物质。
应用
本分析标准品还可作如下用途:
- 通过大体积注射(LVI)气相色谱-真空紫外光谱(GC-VUV)同时鉴定和定量甲基衍生后血浆样品中的脂肪酸
- 采用近红外光谱法(NIRS)结合改进偏最小二乘(MPLS)和偏最小二乘(PLS)回归法测定从 93 种不同向日葵品种提取的葵花籽油的脂肪酸组成
- 采用—偏最小二乘法(PLS)、PLS-无信息变量消除法(UVE)、PLS-竞争自适应重加权抽样法(CARS)和多元线性回归法(MLR)-UVE四种不同组合方法,结合近红外光谱(NIR)对 186 份沙棘籽油样品中的棕榈酸、油酸、亚油酸和亚麻酸进行分离和定量
- 使用基于气相色谱-火焰电离检测(GC-FID)的无衍生法分析油酸及其它相关脂肪酸的多残留
- 无需任何事先的样品处理,使用基于超高效液相色谱-质谱(UHPLC)方法的分离、鉴定和测定 8 种不同商业橄榄油样品中的八种饱和和不饱和脂肪酸

The intimate relationship between stoichiometry and physicochemical properties in transition-metal oxides makes them appealing as tunable materials. These features become exacerbated when dealing with nanostructures. However, due to the complexity of nanoscale materials, establishing a distinct relationship between structure-morphology and
