Boosted efficiency ion source

High-sensitivity ion source for GCMS-TQ8050 NX

Detection at the attogram level

Analysis results for octafluoronaphthalene (1 fg, n=8)

Example: analysis of octafluoronaphthalene

With the increase in sensitivity, the instrument detection limit (IDL) is improved. The figure shows an example analysis of octafluoro-naphthalene. With an IDL of 0.14 fg, detection on the order of attograms becomes possible.

Reliable analysis of dioxins

Until now, analysis of dioxins in foodstuffs has been carried out using GC-HRMS (double-focusing GC-MS). However, with the increase in GC-MS/MS capabilities, the EU has issued regulations (EU589/2014,644/2017) which grant analysis methods using GC-MS/MS the same status in compliance regulations as methods using GC-HRMS. The BEIS therefore provides an optimal solution for those looking to move from GC-HRMS to GC-MS/MS for high-sensitivity analysis of dioxins in ultra-low concentrations.
