“…Most modern methods involve the use of high-performance liquid chromatography (HPLC) and differ mainly with regard to the extraction methods and phases used (4)(5)(6)(7)(8)(9). HPLC has also been employed for the analysis of some organic peroxides (10)(11)(12)(13).…”

A method has been developed for the extraction and analysis of the antioxidant, the peroxide crosslinking agent and some decomposition products in crosslinked polyethylene. The method involves the use of high-performance liquid chromatography (HPLC) in the reverse-phase mode, with a mixture of methanol and water as the mobile phase. Samples of polyethylene are ground at low temperature into a fine powder prior to extraction by methanol. The accuracy and sensitivity limits are given for each of the separated components.

“…The literature contains little information with regard to determining organic peroxides using electrochemical based techniques except for polarographic (dc), [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] biamperometric (or dead stop end-point), 23,24 coulometric (controlled-potential), 25 etc., techniques employed more than a quarter century earlier. The high-performance liquid chromatographic (HPLC) determination of organic peroxides and hydroperoxides has been performed with various spectroscopic modes of detection such as UV, [26][27][28][29][30][31][32] IR, 30 NMR, 30 mass spectrometric 30 and chemiluminescence. 33,34 The relatively few publications dealing with liquid chromatography utilizing amperometric detection, in applications involving organic peroxides and hydroperoxides, have involved reductive mode detection approaches at gold amalgamated, [35][36][37] dropping mercury, 37 glassy carbon, 38 and platinum 39 electrodes and, more recently, electrocatalysis at iron phthalocyanine chemically modified electrodes.…”

Reversed-phase high-performance liquid chromatography with oxidative amperometric detection was optimized for the determination of several organic peroxides in drinking water under ideal conditions. The determinations were performed under isocratic conditions using acetonitrile and methanol as the organic modifiers with 0.05 M potassium phosphate buffer solution. The oxidative amperometric response of the organic peroxides was dependent on the concentration of organic modifier and the electrode potential. The optimum electrode potential (EOxAPP), for the simultaneous determination of the organic peroxides was approximately +1.150 +/- 0.05 V versus the Ag/AgCl reference electrode. The maximum analytical signal for butan-2-one peroxide and tert-butyl hydroperoxide, when using acetonitrile, was obtained with 20% v/v organic modifier. For cumene hydroperoxide, the maximum analytical signal was achieved with approximately 35% v/v acetonitrile. The retention time of cumene hydroperoxide, on an octyldecylsilane column (250 x 4 mm id), decreased sharply from > 100 to < 10 min when the organic modifier concentration was varied from 5 to 50% v/v. The retention time of butan-2-one and tert-butyl hydroperoxide, under the same conditions, varied by < 10 min. The calibration curves for the aliphatic peroxides and aromatic peroxide were linear from 2 to 200 ng and from 0.2 to 200 ng injected, respectively.
