Thus the weight % of Santonox R in high density polyethylene = 2/5 x the level of Santonox R present in the 2 ml chloroform solution (as determined by thin-layer chromatography in % w/v). [Pg.186]

Place 20 pi of the chloroform extract of the polyethylene sample as a spot on a thin-layer plate. Also apply 20 pi aliquots of standard solutions of Santonox R in chloroform (0.05%, 0.04%, 0.03% w/v). Develop the chromatogram to a distance of 10 cm in a chromatography tank containing petroleum ether (40 60)/ethyl acetate (5 1 viv mixture) as the eluent. [Pg.244]
