Meeting the Upcoming European Commission Performance Criteria for the Use of Triple Quadrupole GC-MS/MS as a Confirmatory Method for PCDD/Fs in Food and Feed Samples

Instrument Type: GCMSMS

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) constitute a group of highly toxic organic compounds. PCDD/Fs have been characterized by the US Environmental Protection Agency as likely to be carcinogenic to humans. Recent technological advances in GC-MS/MS technology led to GC-MS/MS being considered a reliable tool that can be used to control the maximum levels for PCDD/Fs in food and feed. In this work, the performance of the Thermo Scientific TSQ 8000 Evo triple quadrupole GC-MS/MS for the analysis of PCDD/Fs was assessed.

Increasing Productivity in FAMEs Analysis through Increased Selectivity

Instrument Type: GCMSMS

In this work, the performance of the Thermo Scientific TSQ Duo system is assessed for the quantitative analysis of 11 FAMEs in human blood spot extracts. The TSQ Duo system offers analysts a unique choice by allowing the use of single quadrupole methods and enabling the automatic transition to triple quadrupole on the same system. This application note illustrates the stepwise process of upgrading methods from single quadrupole to triple quadrupole using Chromeleon CDS software.
