## Abstract Two published procedures for glass capillary column production are applied to produce capillaries for chromatography of polar natural compounds. Soda lime glass capillaries, after leaching with aqueous HCL, are either treated with colloidal silicic acid or with barium carbonate and coat

Abstract
The chromatographic properties of potassium fluoride as an additive to the polyethylene glycol stationary phase were investigated. This unique base in organic chemistry was shown to succeed in yielding good results for the analysis of polar compounds, including the primary amines. Glass capillary columns of high selectivity for primary and secondary aliphatic amines were obtained by the “hexane plug” procedure by which a thin layer of KF is deposited on the inner surface of glass capillary columns. Some possible types of donor‐acceptor interactions occuring within the system PEG/KF/solute were considered.

The PCI mass spectrum obtained with methane as reagent gas yielded a molecular ion peak at m/z 217 (M + 1) as the base peak. Other characteristic peaks were also discernible at m/z 245 (M + 29) and 257 (M + 41) (Figure 3B). Selective ion monitoring (SIM) could be used to quantify 1.0 ng of the deriv
