Identification and analysis of polymer additives using packed-column supercritical fluid chromatography with APCI mass spectrometric detection

Supercritical Fluid Chromatography: A Green Approach for Separation and Purification of Organic and Inorganic Analytes

“…Packed-column supercritical fluid chromatography (pSFC) with atmospheric pressure chemical ionization (APCI) detector and mass spectrometry (MS) provides a versatile method for the detection and quantification of 20 polymer additives, including common antioxidants, light stabilizers and slip agents (Carrott and Davidson 1998) and the additives can also be extracted from the polyethylene polymer by SFE. The attributes of supercritical fluids, especially CO 2 , are extremely attractive in polymer extraction application.…”

Atmospheric pressure photoionization mass spectrometry as a tool for the investigation of the hydrolysis reaction mechanisms of phosphite antioxidants

“…Ionization mechanisms taking place in the ion source were investigated in the latter case and were similar to those previously reported for related structures [23]. Other applications involved the analysis of common antioxidants, slip agents and light stabilizers by SFC/APCI/MS [17] and HPLC/APCI/MS [15,19]. A few applications in the field also deal with the characterization of additives and their degradation pathways [20,21,[24][25][26][27].…”

“…So far, ESI and APCI have been the methods of choice for additive analysis [13][14][15][16][17][18][19][20][21]. Brominated flame retardants, used in a variety of consumer and industrial products, have been successfully analyzed by HPLC/ESI/MS in biological fluids [16] and tissue samples [13,14].…”

Analysis of Polymeric UV Absorber (Tinuvin 213) Using LDI-TOFMS: Solvent Effect in Sample Preparation

“…Moving toward higher molecular weight additives with less volatility, conventional mass spectrometry techniques such as electron ionization (EI), chemical ionization (CI), and gas chromatography/mass spectrometry (GC/MS) are generally not suitable for their analysis. Thus soft ionization techniques such as field desorption, fast atom bombardment (FAB), 9,10 desorption chemical ionization (DCI), 11,12 laser desorption, [13][14][15][16][17][18] electrospray ionization (ESI), 19 and atmospheric pressure chemical ionization (APCI) 20,21 have been investigated for their utilities in the analysis of polymer additives either in polymer extracts or directly from polymer matrices.…”
