The Varian 500-MS LC ion trap is an ion trap based LC/MS system. The 500-MS exceptional sensitivity, mass stability, resolution and enhanced charge capacity (ECC™) makes the 500-MS LC ion trap the system of choice for pharmaceutical, clinical toxicological, environmental, and other applications.
The Varian 500-MS LC ion trap is an ion trap based LC/MS system designed for high sensitivity, mass stability, resolution, and enhanced charge capacity. It serves as a preferred choice for pharmaceutical, clinical toxicological, environmental, and other analytical applications.
The instrument features an Atmospheric Pressure Ionization (API) interface with selectable Electrospray Ionization (ESI) or Atmospheric Pressure Chemical Ionization (APCI) sources. The ESI source supports flow rates from 1 to 1000 pL/min, while the APCI option accommodates flows up to 2 mL/min. Both interfaces utilize a SelecTemp feature for temperature programming of drying gas.
