GC-ICP-MS Interface Kit

The Agilent GC-ICP-MS interface for the Agilent ICP-MS Systems and 7890A GC ensures superior GC-ICP-MS performance in the analysis of volatile organic and organometallic compounds. High-temperature, dry plasma delivers superior sensitivity for high-ionization-potential elements such as Hg, As, Se, and the halogens.

The first commercial GC-ICP-MS interface was developed by Agilent in 2002. This became the benchmark for GC-ICP-MS performance, due to its fully heated transfer line and torch injector, which permit the analysis of high boiling-point (BP) compounds. These innovations, which remain unique, have been enhanced and refined in the new GC-ICP-MS interface.

ICP-MS Accessories

Features

Freedom from background interferences on sulfur and phosphorus, enabling trace measurement at elemental masses
Uniform high temperature maintained all the way to the tip of the ICP injector, preventing peak tailing and loss of high-boiling-point analytes due to condensation in the injector
Reduced length, simpler installation, and more consistent alignment than the previous model
Both the transfer line and ICP injector are independently heated and controlled by the GC
Maximum temperature of 300 °C, allowing high-boiling-point compounds to be quantitatively transferred to the detector
Sulfinert interface liner for passive transfer from the GC column to the injector tip, permitting the analysis of reactive compounds, such as many sulfur species
Argon make-up gas preheat in the GC oven maintains gas temperature at compound elution temperature
The high flow rate of heated argon through the transfer line minimizes the time spent between the GC and ICP torch to less than 100 milliseconds, significantly reducing the opportunity for interaction between the eluting compounds and the transfer line.
Electronic pressure control module (PCM) for optional gases (such as oxygen to decompose carbon)
