WebThe equation for this particular Savitzky-Golay smoothing is defined as follows: y t = (-2x t-3 + 3x t-2 + 6x t-1 + 7x t + 6x t+1 + 3x t+2 - 2x t+3 )/21. The figure below shows the smoothing results (lower trace) for a spiked, … WebThe Golay equation can also be used to examine the dispersion that takes place in connecting tubes, detector cells and other sources of extra-column dispersion. Extra-column dispersion will be considered in another chapter but the use of the Golay equation for this purpose will be briefly considered here.

WebOne can calculate the resolution of a chromatographic system from two consecutive peaks using the following equation: (Equation 8-8)R = 2⋅dW1 + W2 where d is the separation between two peaks (measured from top to top) and W1and W2are the widths at baseline of the two peaks. This is illustrated in Figure 8-5. FIGURE 8-5.

While the van Deemter equation was developed for packed columns, the analogous Golay equation was developed for capillary columns, and they are very similar.[5] Capillary columns do not conrtain a particulate packing, so the A term for eddy diffusion is not included: bbcaraibeWhen the data points are equally spaced, an analytical solution to the least-squares equations can be found. This solution forms the basis of the convolution method of numerical smoothing and differentiation. Suppose that the data consists of a set of n points (xj, yj) (j = 1, ..., n), where xj is an independent variable and yj is a datum value. A polynomial will be fitted by linear least squares to a set of m (an odd number) adjacent data points, each separated by an interval h. Firstly, a c… bbcb tampa
