Shimadzu 8040, 20LC

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. This Shimadzu 8040 LC/MS system with 20 LC comes expertly refurbished from GenTech Scientific.
