摘要
根据实验数据比较了计算EMG参数的五种方法。当采样周期较小时,五种方法的计算值吻合;当采样周期较大时,经典的Yau方法误差较大。本研究提出的图解法改进公式,与文献方法比较,测试简单,有较好的拟合精度,而且更能反映EMG参数间的关系。
Three previously reported methods of extracting the parameters of exponentially modified Gaussian (EMG) model from skew chromatographic peak were compared with the laboratory data.The results calculated by these methods are identical when AD sampling rate is great.However,both graphic methods are more accurate than Yau method when the rate is small.An improved graphic method is derived in this paper.Comparing with the cited methods,it is simpler in measuring,better in accuracy,precision,and characterization of relations among the parameters.
