iCAP TQe ICP-MS: For samples where single quadrupole performance isn’t enough
The issue of spectral interferences in quadrupole ICP-MS and the negative effects these have on trace element data accuracy and detection limits has been known since the early days of the technology.
During the 1990’s, the advent of collision cell technology enabled significant reduction of a range of the most well-known interferences, such as ArO (on Fe), ArCl (on As) and ArAr (on Se) to be achieved, but challenges, such as doubly-charged ion and isobaric (same isotope mass) overlap interference, remained. The development of triple quadrupole ICP-MS in the last few years has provided a solution to these challenges by enabling much more selective interference control. With triple quadrupole instruments, this selectivity is achieved through a combination of mass pre-filtering prior to the collision cell of the instrument and use of reactive gases, such as oxygen, hydrogen and ammonia in the cell, to remove interferences via chemical reactions. In part 1 of this this 2-part webinar series, the theory and practice of triple quadrupole ICP-MS in comparison to single quadrupole ICP-MS will first be presented. The focus of the presentation will then move on to the performance of a new, workhorse instrument that utilises only He and O2 collision / reaction cell gases to remove the most commonly encountered interferences, the Thermo Scientific™ iCAP™ TQe triple quadrupole ICP-MS.
Key takeaways from the webinar:
What performance advantages triple quadrupole ICP-MS offers over single quadrupole instruments
Which elements benefit from the enhanced interference removal capabilities of triple quadrupole technology
What range of instruments are available for meeting the demands of both high throughput, day-to-day applications and research studies
Who should attend:
Analysts working in the area of elemental analysis
Laboratory managers looking to improve their trace element data accuracy
Research academics and students who need more flexible ICP-MS technology for removing elemental interferences and reducing detection limits
