Application of a purge and trap TDS-GC/MS procedure for the determination of emissions from flame retarded polymers

Quality Concepts for the Improved Use of Recycled Polymeric Materials: A Review

“…HPLC‐UV/MS has been employed to identify and quantify 15 brominated and phosphorous‐based flame retardants in polymer fractions from WEEE; however, a combining procedure using size exclusion chromatography (SEC) and HPLC‐UV appears to be a more suitable procedure for routine flame retardant screening in actual recycling facilities, thanks to easier operating and maintenance of the equipment 60. No indication of intensive decomposition during repetitive processing of flame retarded styrenic polymers was observed using chromatographic techniques in different studies;64, 65 however, evidence of several bromine‐containing fragment emissions from polymers with flame retardants were shown using thermo‐desorption gas chromatography‐mass spectrometry (TDS‐GC/MS) 66. Further attention will be given in the future to the determination of BFR emissions and degradation compounds during use and recycling of polymers with flame retardants.…”

Formation of hydrogen bromide and organobrominated compounds in the thermal degradation of electronic boards

“…Most of the former studies were dedicated to shed some light on the possible formation of extremely hazardous compounds, as polybrominated dibenzo-p-dioxins (PBDD) and polybrominated dibenzofurans (PBDF), in the oxidation of BFRs [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. More recently, several investigations were dedicated to the distribution of bromine among the thermal degradation products of the more common BFRs, as tetrabromobisphenol A (TBBA) and hexabromocyclododecane (HBCD) [20][21][22][23][24][25][26][27][28][29], and of materials containing BFRs [26,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. The results obtained evidenced that, apart the formation of extremely dangerous compounds as PBDD and PBDF, hazards may derive also from the formation of relevant quantities of hydrogen bromide and high molecular weight brominated compounds.…”

Molecules and indoor atmospheric effect of rosewood: Dalbergia granadillo

“…The ion source and the quadrupole temperature were set to 230 °C and 150 °C, respectively. The analytical standard library was analyzed via NIST14.L [19][20][21].…”
