Abstract
A cross-linking co-agent was used in the immobilization of polyethylene glycol (PEG) 20M peroxide to produce a capillary column for gas chromatography. The co-agent promoted the immobilization of PEG 20M and the concentrations of peroxide necessary to achieve over 80%, non-extractability decreased from 15% for PEG 20M immobilization by the peroxide alone to 5 and 3% for PEG 20M immobilization using 3 and 5% of the co-agent in PEG 20M, respectively. The use of the co-agent suppressed the decrease in column efficiency and the increase in column polarity which occur in immobilization using the peroxide alon. The co-agent also increased the thermostability of the column. The mechanism of the participation of the co-agent in the immobilization of PEG 20M is discussed.
