窄脉冲原子吸收光谱仪主机线路Ⅱ型应用于医学临床微量元素分析。根据我们发现的镍离子线231.6nm 可以被任意改变的客观规律,有效地减少了谱线的热变宽、自吸收和离子线干扰。从而,全面地改善了原子吸收光谱仅的实用性能,它比方波线路能量值大100倍以上,具有更好的信噪比、抗干扰能力、更好的灵敏度和背景扣除能力。 Narrow pulse atomic absorption spectrometer host line Ⅱ used in clinical analysis of trace elements. According to the objective law that we found that the nickel ion line 231.6nm can be arbitrarily changed, the heat broadening, self-absorption and ion-line interference of the line are effectively reduced. Thus, the overall improvement of the atomic absorption spectrometry only practical performance, which is more than 100 times the square wave line energy value, with better signal to noise ratio, anti-interference ability, better sensitivity and background subtraction ability.
