Lower Detection Limits
Varian’s proven state-of-the-art GC/MS interface features interchangeable ion volumes for robust operation with challenging matrices. And the superior design characteristics don’t end at the ion source. Varian’s patented 180º curved collision cell provides additional noise reduction for complex matrices.
Compact, Sensitive, Flexible The 320-MS has been designed to deliver performance and productivity. Varian’s innovations include:
Single dual-stage, turbomolecular pump Split flow, differential pumping for the source and analyzer produces a compact, economical instrument.
Ultra-low noise detector Directly aligned with the ion path for better sensitivity, especially in CI.
High performance quadrupoles Pre- and post-ion guides improve transmission efficiency. The absence of lenses simplifies tuning and improves signal.
Dual Source Switch from EI to CI without breaking vacuum.
Convenient Switchability The 320-MS gives you the most options for configuring the instrument to meet your needs:
Switch from GC to LC interface and back again
Change ionization modes between EI and CI
GC sources include: EI, PCI and NCI
Single Quad to Triple Quad upgrade
Our Best Gas Chromatograph The 450-GC is Varian’s top of the line gas chromatograph with a flexible platform for single, dual, or three-channel configuration for maximum productivity.
