Rapid analysis of phthalates for RoHs2 by Py-GC-MS
MSTips No. 298
Phthalates are used as plasticizers for resins, but their use is restricted by various regulations due to concerns about their effects on the human body as endocrine disruptors. The revised RoHS Directive (RoHS2), which came into effect on July 22, 2019, regulates four phthalats (diisobutyl phthalate: DIBP, dibutyl phthalate: DBP, butyl benzyl phthalate: BBP, di-2-ethylhexyl (DIBP, DBP, butyl benzyl phthalate: BBP, di-2-ethylhexyl phthalate: DEHP) were regulated. As measurement methods for these substances, the solvent extraction-GC/MS method for precise analysis and the Py-GC/MS method for screening are specified in IEC-62321-8. We have attempted a rapid analysis of Py-GC/MS method using JMS-Q1500GC by optimizing Py and GC oven conditions, and achieved a cycle time of 14.75 min per measurement. Here, we report the results.
