针对色谱重叠峰的分峰效率低和计算误差不稳定问题,研究了基于函数平分迭代的重叠峰分峰方法。利用函数平分迭代,重新确定了色谱单峰的顶点,加快了色谱重叠峰的分离;设定计算误差,控制函数平分迭代的进程。结果表明,应用该方法分离重叠峰后,与常规的3种方法相比,重叠峰的计算误差更稳定,迭代效率提高了11%,具有一定的优势。
Aiming at the problem of low peak efficiency and unstable calculation error of overlapping chromatographic peaks, the method of peak aliasing based on bisection function iteration is studied. By using function bisection iteration, the vertexes of chromatographic single peaks are re-determined and the separation of chromatographic overlapping peaks is accelerated. The calculation error is set and the control function bisects the process of iteration. The results show that the proposed algorithm can separate the overlapping peaks more stably than the conventional three methods, and the iterative efficiency is improved by 11%, which has some advantages.
