This document introduces the Agilent GC-ICP-MS method for rapid and sensitive detection of polybrominated diphenyl ethers. The method has a wide dynamic range and high sensitivity and can be used for the detection of complex samples.
This document describes a technical application using Gas Chromatography combined with Inductively Coupled Plasma Mass Spectrometry (GC-ICP-MS) to analyze Polybrominated Diphenyl Ethers (PBDEs). The text highlights the advantages of this method, including high sensitivity for poorly ionized elements like halogens and absolute selectivity between different halogens without interference from fluorine, chlorine, or iodine.
The specific experimental setup detailed involves an Agilent 6890 GC connected to an Agilent 7500a ICP-MS via the Agilent GC-ICP-MS interface. The document discusses the system's ability to detect low levels of PBDEs in complex matrices, such as commercial PCB standards, and mentions features like Compound Independent Calibration (CIC) for quantifying compounds where standards are unavailable.
The test used a mixture of commercial PCB standards at a total concentration of 500 ppm.
The calibration graph for PBDE-183 covers a range from 10 ppb to 1 ppm.
The total retention time for the mixture is less than 10 minutes.
