Key Features
-
Inert Ion Source Design
The 5975 Inert MSD features an inert ion source for improved response, especially to active compounds and late-eluting analytes. -
Extended Mass Range & High Sensitivity
Runs up to m/z 1050, with enhanced sensitivity (e.g., EI scan 182:1 S/N at 1 pg OFN; CI scan up to 500:1). -
Standard Turbo Pump, Robust Vacuum System
Equipped with the standard turbomolecular pump for stable operation; straightforward maintenance with a user-friendly design. -
AutoCI™ Capability
Enables fully automated switching between EI and CI modes within a sequence, streamlining method setup and reducing manual intervention. -
Modular and Service-Friendly Construction
Features such as quick-swap interfaces and a functional front window allow easier filament and column access, reducing downtime. -
Precision Sampling & Minimal Carryover
The 7683 ALS provides injection volumes from 0.1 µL to 50 µL, variable sampling depths, and dual solvent washes to virtually eliminate carryover. -
High Throughput and Flexibility
Dual simultaneous injection, priority sampling, and next-sample overlap enhance throughput—ideal for busy labs.
Applications
-
Environmental Analysis: Pesticides, pollutants, and emerging contaminants
-
Forensics & Toxicology: Trace-level compound identification
-
Pharmaceuticals & Metabolomics: Profile drug compounds and metabolites with high sensitivity
