Description
The LCMS-8040 was designed to provide significantly higher sensitivity while maintaining the high speed offered by the LCMS-8030. Ultrafast MRM transition speeds, up to 555 MRMs per second (dwell times of 1 msec and pause times of 1 msec) are achieved. In addition, the LCMS-8040 features the polarity switching at 15 msec and high speed scanning rate of 15,000 u/sec. By incorporating newly improved ion optics UF-Lens™ and UFsweeper™ II collision cell technology, the LCMS-8040 provides higher multiple reaction monitoring (MRM) sensitivity. This higher sensitivity expands the potential range of LC/MS/MS applications.
Ultra-High Sensitivity
By incorporating newly improved ion optics and collision cell technology, the LCMS-8040 provides higher multiple reaction monitoring (MRM) sensitivity. A five-fold increase in sensitivity (reserpine, S/N ratio), as compared with that of LCMS-8030 has been achieved by improving ion focusing and minimizing ion losses between multi-pole lenses. These improvements also yield higher sensitivity for scan mode measurements. This higher sensitivity expands the potential range of LC/MS/MS applications.
Ultra-High Speed
The LCMS-8040 was designed to provide significantly higher sensitivity while maintaining the high speed offered by the LCMS-8030. Ultrafast MRM transition speeds, up to 555 MRMs per second, are achieved by Shimadzu’s UFsweeperTM collision cell technology, proprietary high-precision quadrupole machining capabilities, and unique high voltage power supply technology. In addition, the LCMS-8040 features the fast polarity switching at 15 msec. With this high-speed performance, the LCMS-8040 can dramatically improve analytical throughput.
Ultra-High Reliability
MRM optimization in Shimadzu’s LCMS systems is based on a rapid series of automated flow injection analyses, requiring only minutes to perform. Multiple compounds can be optimized in an unattended sequence, freeing the analyst from tedious work. MRM parameters optimized for the LCMS-8030 can be transferred to the LCMS-8040, making it possible to transfer methods between systems. The LCMS-8040 offers the same ease of maintenance benefits as the LCMS-8030, and all consumables, such as desolvation lines (DL) and ESI capillaries, are interchangeable as well.
Exceptional Durability
Blood plasma samples were spiked with verapamil and warfarin, and then protein precipitation was carried out according to the pretreatment flow indicated below. The area values from 450 consecutive LCMS-8040 analyses were then plotted. Simultaneous analysis of verapamil by ESI+ and warfarin by ESI− was performed. Chromatograms for the 1st, 250th, and 450th measurements are shown below. This resulted in 1 pg on-column area repeatability of 4.18% for verapamil and 6.61% for warfarin.
