ICP-MS is a GC detector that provides universal, element-specific quantification. It offers rapid multi-element/isotope analysis and very high sensitivity.
The text details an analytical study connecting an Agilent 7890A Gas Chromatograph (GC) to an Agilent 7700x Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The connection utilizes a new GC interface kit featuring a passivated, heated Sulfinert tube and a special torch with a heated injector to maintain constant high temperature and inertness.
The document presents results for three specific analyses: organo-tin compounds in seafood and blood samples, polybrominated diphenyl ethers (PBDEs) as flame retardants, and sulfur species in diesel fuel. The study demonstrates that this interface allows ICP-MS to provide universal, element-specific quantification with high sensitivity, achieving detection limits of 5.9 ppt for tributyl tin and 150 ppt for decaBDE.
The analysis achieved a detection limit of 5.9 ppt for tributyl tin.
The analysis achieved a detection limit of 5.9 ppt for tributyl tin (TBT).
The monitored masses for the organo-tin analysis are m/z 79 and 81.
