GC/MS application notes help to determine polybrominated diphenyl ethers (PBDEs) in environmental and electronic/electrical samples using the DSQ mass spectrometer.
Thermo Electron is offering two GC/MS application notes for the determination of polybrominated diphenyl ethers (PBDEs) in environmental and electronic/electrical samples using its DSQ mass spectrometer.
The new application notes are entitled 'Quadrupole GC/MS Analysis of PBDEs in Environmental Samples' and 'Fast, Sensitive and Reliable Analysis of PBDEs by GC/MS'.
Both demonstrate how the DSQ helps environmental laboratories and regulatory agencies, as well as manufacturers and importers of electrical and electronic equipment, comply with the strict EU regulations relating to Restrictions of Hazardous Substances (ROHS) and Waste Electrical and Electronic Equipment (WEEE).
The ROHS/WEEE regulations aim to minimising the presence of PBDEs in various types of electrical and electronic components such as power cables, insulation wires, connectors and sockets.
The company's application notes feature effective methods for detecting and identifying specific PBDE congeners in small amounts.
The first application demonstrates the DSQ's ability to scan up to 1050 amu to allow molecular spectra to be obtained for every PBDE congener.
In the second application, a narrow-bore GC column is combined with the fast scan rate of the DSQ, achieving the analysis of 21 PBDE congeners in less than 11 minutes, claims the firm.
Without repeating the sample injection, the simultaneous acquisition of full scan and SIM data from the same chromatographic run has been used for analyte confirmation in the environmental and electronic samples, while retaining the sensitivity and selectivity of the target compound analysis by SIM, says the company.
