Simultaneous Determination of Antioxidants and Ultraviolet Stabilizers in Polyethylene by HPLC

Analysis of Additives in Plastics

“…Among the various polyolefi n additives, antioxidants are commonly determined qualitatively or quantitatively by GC [59], GC-MS [60,61], or HPLC [62], and analysis using hyphenated techniques that combine HPLC with various means of detection (MS, NMR, IR, etc.) has also been explored [63].…”

Study on fluorimetric properties of 1,2-dihydro-2,2,4-trimethylquinoline

“…Numerous papers have described the estimation of various types of antioxidants used in polymer manufacturing [1][2][3][4][5][6][7][8][9][10][11]. The need for their analysis is very important, particularly in connection with medical plastics and food packaging where the levels of such potentially toxic substances must be accurately known.…”

“…Many sophisticated techniques have been proposed for the analysis of these antioxidants, including laser desorption/Fourier transform ion cyclotron resonance mass spectrometry [1], supercritical fluid extraction combined with GC-MS [2], pyrolysis-gas chromatography [3][4] and HPLC [5]. However, these techniques still do not satisfy all *Corresponding author.…”
