SCIEX has launched the SCIEX Triple Quad™ 5500+ LC-MS/MS System—QTRAP® Ready, coupling triple quadrupole and QTRAP functionality in a single system. The QTRAP functionality can be implemented at any time by simply activating a field upgradable licence. Increased Polarity Switching Time provides increased efficiency of positive- and negative-ion analysis in the same acquisition (with 5 ms in MRM and Scheduled MRM™) analysing more analytes in a single run without compromising data quality. There is Linear Dynamic Range of up to six orders. QTRAP functionality: 12,000 Da s–1 enables rapid qualitative confirmation of analytes in parallel with MRM quantitative data.
