Agilent Technologies Inc. has announced the 6490 Triple Quadrupole LC/MS System with iFunnel technology. iFunnel technology revolutionizes the process of atmospheric pressure ion sampling, driving sensitivity gains for most applications, the company claims.

The new system has a 25 percent smaller footprint than previous models, while boasting a sensitivity specification that is 10 times higher.

iFunnel technology relies on Agilent Jet Stream technology thermal gradient focusing to create a high abundance of accessible gas phase ions. These ions are then drawn into the mass spectrometer through a Hexabore Capillary sampling array, six parallel capillaries that accept nearly 12 times more ion-rich atmospheric gas than previous systems. The ions are focused and separated from the gas by a Dual Ion Funnel assembly.

The first high-pressure funnel can remove most of the gas and focuses the ions into the second low-pressure funnel, which can removethe remainder of the gas so that the ions can enter the Q1 optics.

“Triple quads are considered mature technology, yet we have been able to consistently improve their performance with a succession of product introductions over the past 4 years,” said John Fjeldsted, general manager of Agilent’s LC/MS business. “It is not very often that you can take a huge step forward as we are this year with the iFunnel technology. It establishes a whole new paradigm for atmospheric ion sampling.”

In addition to iFunnel technology, the instrument also has a new curved, tapered collision cell. This device allows a compact system design and reduces noise to help improve overall sensitivity, Agilent claims.

Combined with the 1290 Infinity UHPLC system, the 1290/6490 system with MassHunter software delivers the highest available level of quantitative analytical LC/MS performance, according to the company. The 6490 is the fourth triple quadrupole product introduced by Agilent in the past four years and joins the 6410, 6430 and 6460 Triple Quad systems to create a portfolio that can meet the needs of any application or budget.

The innovative 6490 ushers in a new frontier of application possibilities with the ability to detect molecules at the zeptomole (10-21 mole) level. The iFunnel technology also enables a linear dynamic range that extends to six orders of magnitude for many compounds.
