摘要:
AbstractIn previous papers Jansson's method was found to be successful at deconvolving severely overlapped gas chromatographic peaks. In the most recent paper the method was evaluated with respect to quantitative accuracy, peak area and retention time repeatability. The problems associated with deconvolving noisy data and some alternatives which can improve the ability of Jansson's method to deconvolve noisy data are discussed. These alternatives include presmoothing the data with a nine‐point, third‐order polynomial filter and data reblurring. This paper will test these methods on peaks with various degrees of resolution and signal‐to‐noise
