LCMS-8040 Triple Quadrupole Liquid Chromatograph Mass Spectrometer (LC-MS/MS)
Consumer demand for higher quality products has led to the implementation of stricter government regulations and oversight in order to ensure safety and product conformity. The food safety community is just one sector requiring lower minimum residue levels with greater testing frequency for a broader number of compounds. The triple quad LCMS-8040 has stepped up to the challenges of high-throughput sensitive routine analysis. As shown, the LCMS-8040 can analyze a 226 pesticide mixture in less than two minutes, making it an ideal instrument for meeting a laboratory’s demanding requirements.
UFsweeper II – Enhanced Sensitivity
The UFsweeper II, a redesigned pseudo-quadrupole collision cell, allows for 1msec pause times with better ion transmission out of the cell. This practically eliminates crosstalk, yielding high quantitative accuracy and reliability even at lower levels of detection.
Using ultrafast chromatography and the ultrafast sampling rate provided by the LCMS-8040 Triple Quadrupole Mass Spectrometer, sub 100 femtogram levels of detection have been obtained for certain analytes.
LCMS-8060 Triple Quadrupole Liquid Chromatograph Mass Spectrometer (LC-MS/MS)
Shimadzu has redefined “sensitivity” with the LCMS-8060. The newly developed UF-Qarray ion guide incorporates groundbreaking technology that increases LC-MS/MS sensitivity by enhancing ion signal intensity and reducing noise. By improving the ion sampling device, the ion guide, and the vacuum efficiency, the LCMS-8060 delivers a new standard for sensitivity.
The innovative design of the Qarray allows for enhancement of ion signal while simultaneously reducing noise. This yields ultra-low detection limits, allowing for trace quantitation.
In addition to obtaining high-quality data with extraordinary sensitivity, the LCMS-8060 delivers qualitative information concurrently. Product ion scans can be triggered by a pre-set threshold. This enables the simultaneous collection of multiple MRM events with full scan product ion spectra at different collision energies.
The LCMS-8060 delivers the fastest quadrupole scan speed of up to 30,000 u/second with a 0.1 Dalton step size without the loss of mass accuracy. With the fastest polarity switching available, switching acquisition mode from positive to negative only takes 5 msec. Data acquisition occurs so rapidly that triggered MS/MS scans and MRM quantitation can be performed in a single acquisition method.
