Features of 325-MS

  • Accurate and reproducible results in difficult matrices

  • Highest sensitivity amongst comparable triple-quadrupole instruments (500 femtograms reserpine)

  • Easy-to-use vESI interface

  • Increased number of target analytes possible in multi-residue methods

  • Reduced need for front-end maintenance

    It features a "vortex" API interface (vESI; petent pending) and "Gold-Guard" (patent pending) ion-optics that jointly enhance sensitivity, ruggedness and throughput. The higher sensitivity means you can analyze more compounds in a single run. The more rugged design means less downtime for cleaning the source. That adds up to an extremely productive solution.
