The determination of chlorine in plastic using isotope dilution inductively coupled plasma mass spectrometry

Abstract

The determination of chlorine (Cl) in plastic using isotope dilution inductively coupled plasma mass spectrometry (ID-ICPMS) combined with different sample pretreatment procedures was examined in the present study.

Challenges and trends for halogen determination by inductively coupled plasma mass spectrometry: A review

“…39 Furthermore, a mass-shift approach using DRC with H 2 as the reaction gas has been used to shift 35 Cl to 35 Cl 1 H 1 H + and 37 Cl 1 H 1 H + , leading to lower LODs. 44,45 In addition to chlorine, DRC has also been used to eliminate interferences for bromine and iodine determination by using H 2 as a reaction gas. 46,47 In the case of 129 I determination, isobaric interference by 129 Xe, a common contaminant in Ar gas, can be removed by using O 2 as a reaction gas.…”

“…67 This approach was also applied together with ICP-QQQ in mass-shift mode using H 2 as a reaction gas for chlorine determination. 45 Highly sensitive and precise chlorine isotope ratio measurements were performed without interferences, such as 16 O 18 O 1 H and 36 Ar 1 H on 35 Cl and 37 Cl, respectively. 45 Finally, it is important to mention that the determination of halogens has been an important task for more than 40 years 87-92 but it has received increased attention in recent years, especially with the development of multi-element techniques, such as ICP-MS.…”
