脉冲-色谱法定氢在国内外已获得广泛的应用。定氢工作曲线的标准物,有纯氢(气标)和金属中氢的标准(固标)两种。固标由于制备及保存等的困难,其品种和数量廖廖无几。因此,在日常分析中往往采用气标,但实验结果表明,气标与固标的工作曲线是不一致的。本文在实验基础上,提出了一种气标校正系数法,经标样考察和两年多配合分析表明,采用气标校正系数法所得的分析结果准确可靠。对于固定的仪器,在一定的实验条件下,K_(?)是个常数。因此在日常分析中可以用气标代替固标。方法简便,准确可靠,经济。
Pulse-Chromatography Hydrogen has been widely used at home and abroad. Hydrogen standard curve of the working curve, a pure hydrogen (gas standard) and metal in the hydrogen standard (fixed) two. Due to the difficulties of preparation and preservation, the variety and quantity of fixed labels are endless. Therefore, gas gauges are often used in routine analysis, but the experimental results show that the working curves of gas gauges and fixed gauges are inconsistent. In this paper, based on the experiment, a gas calibration coefficient method was proposed. The standard calibration and two-year multi-calibration analysis showed that the calibration results obtained by gas calibration method were accurate and reliable. For a fixed instrument, under certain experimental conditions, K_ (?) Is a constant. Therefore, in routine analysis can be used instead of fixed gas standard. The method is simple, accurate, reliable and economical.
