全差示分光光度法是我国近年来发展起来的一项新方法。此法的主要优点是精密度好(相对偏差可降至0.4%乃至0.2%以下),灵敏度高(与普通法比可提高10—20倍),测定范围广(可以从痕量测至高量:0.000X—99.X%)。我们试验用此法以过
Full differential spectrophotometry is a new method developed in recent years in our country. The main advantages of this method are good precision (relative deviation can be reduced to 0.4% or even below 0.2%), high sensitivity (10-20 times higher than the common law), wide range of measurement (from trace to high volume: 0.000X-99.X%). We experiment with this method too
