Engineered for Robustness and

Easy Operation/Maintenance
Newly Designed Ionization Unit

The robustness of the LCMS-8060 and modified ion optics was a deuterated internal standard (alprazolam-d5) the RSD was 3.5%. Designed without cables or tubes, removing the new ionization unit is simple: release a one-touch lever to open the unit and lift it out. In
also assessed by injecting 2400 samples of femto-gram levels of As part of the robustness test the vacuum system was vented to addition, no tools are needed to detach the needles fitted in APCI and DUIS units, allowing for easy maintenance.

Easy System Maintenance Reduces Downtime ESI (standard) APCI (optional) DUIS (optional)

As with Shimadzu’s other triple quad systems, maintaining the LCMS-8060 is simple. Replacing the desolvation line (DL) and ESI capillary
is quick and easy. Additionally, the design allows users to replace the DL without breaking vacuum, providing greater uptime and usability.
