水质分析概念详解(4):原子吸收光谱 水质分析概念详解(4):原子吸收光谱Atomic-Absorption Spectroscopy (AA)
Introduction
Atomic-absorption (AA) spectroscopy uses the absorption of light to measure the concentration of gas-phase atoms. Since samples are usually liquids or solids, the analyte atoms or ions must be vaporized in a flame or graphite furna…… http://www.samsco.com.cn/info/46035.htm
水质分析概念详解(5):重量分析法 水质分析概念详解(5):重量分析法Gravimetry
Introduction
Gravimetry is the quantitative measurement of an analyte by weighing a pure, solid form of the analyte. Obtaining pure solids from solutions containing an unknown amount of a metal ion is done by precipitation.
Since gravimetric analysis is an absolute me…… http://www.samsco.com.cn/info/46036.htm
水质分析概念详解(1):校准(calibration) 水质分析概念详解(1):校准(calibration)Calibration
Making measurements with any analytical method or instrument requires calibration to ensure the accuracy of the measurement. There are two common calibration procedures: using a working curve, and the standard-addition method. Both of these methods require …… http://www.samsco.com.cn/info/46033.htm
