Abstract
Poly(methyloctylsiloxane), PMOS, can be thermally immobilized in porous sil ica particles at temperatures of 80 to 150 degreesC to produce monolayer st ationary phases and efficient reversed phase columns. Thermal immobilizatio n at higher temperatures (180-280 degreesC) produces thicker ("bi-layer") s tationary phases with much lower HPLC efficiencies - in marked contrast to the efficient "bi-layer" stationary phases previously obtained by gamma-rad iation immobilization of PMOS.
