The Varian 325-MS is a triple quadrupole mass spectrometer that is suitable for environmental, food safety, clinical research and forensic applications. It features Varian's patent pending vESI™ ion source, a vortex API, and patent pending Gold Guard™ ion optics that jointly enhance sensitivity, ruggedness and throughput.
The Agilent 325-MS Triple Quadrupole Mass Spectrometer is a rugged instrument designed for high-throughput analysis of small molecules in applications such as environmental testing, food safety, and forensics. Originally manufactured by Varian, Inc., this document notes that the company was acquired by Agilent Technologies in May 2010, though the text retains historical references to Varian.
Key features include the patent-pending vESI ion source, which uses a vortex mechanism to improve desolvation efficiency and sensitivity, and the Gold Guard ion optics, engineered to resist contamination from complex matrices. The system is presented as a complete solution that integrates with Varian's HPLC pumps and autosamplers for streamlined workflow.
| Ion Source Technology | vESI ion source with vortex mechanism |
