近代分析仪器品种繁多,应用广泛。例如气相色谱仪/质谱计/计算机联用仪能对含有几十种组分的复杂混合物自动进行定性定量分析,记录下全部成分的分析数据。某些离子选择电极的灵敏度高到能够检测出每滴溶液中一个离子的浓度。电子探针和离子探针能够对固体样品表面逐个微点或逐个原子地进行微区扫描分析和深度分析。有些分析仪器的探头大小到可以深入动物或人体内部,分析生物体液。还有一些分析仪器具有
A wide range of modern analytical instruments, widely used. For example, GC / MS / MS can automatically and qualitatively and quantitatively analyze complicated mixtures containing dozens of components, and record the analytical data of all the components. Some ion-selective electrodes are so sensitive as to be able to detect the concentration of one ion per drop of solution. Electron probes and ion probes enable micro-scan and depth analysis of solid sample surfaces on a micro-point or atom-by-micro basis. Some analytical instruments probe size can be deep into the animal or human body, the analysis of biological fluids. There are some analytical instruments available
