Chromatographic Columns - Chemistry LibreTexts

Gas Chromatographic Columns. In gas chromatography the mobile phase is a gas. Gas chromatographic columns are usually between 1 and 100 meters long. Gas liquid chromatography(GLC): The liquid stationary phase is bonded or adsorbed onto the surface of an open tubular (capillary) column, or onto a packed solid support inside the column.Matching the polarities of the analyte and stationary phase ...

8.10 ARIMA vs ETS | Forecasting: Principles and Practice

Forecasting: Principles and Practice. 8.10 ARIMA vs ETS. ... In particular, all ETS models are non-stationary, while some ARIMA models are stationary. The ETS models with seasonality or non-damped trend or both have two unit roots (i.e., they need two levels of differencing to make them stationary). All other ETS models have one unit root (they ...

1.1 1-D Spectra via Method of Stationary Phase

The governing principle behind the method of stationary phase will be introduced by example. Consider an integral of the general form: I[k]= Z +∞ −∞ r[x] eik·µ[x] dx (1) where r[x] and µ[x] are real-valued functions and kis a selectable real-valued para-meter. The exponential function eik·µ[x] oscillates at a rate that depends on both k

stationary phase. Other things being equal, a compound band will move through the column more quickly if its distribution favors the mobile phase. Boiling points are often used as a measure of the relative volatilities of compounds in a mixture. However, volatility alone does not determine the distribution between the stationary and mobile phase.
