Varian 1200L Triple Quadrupole Liquid Chromatography-Mass Spectrometer (Used, Refurbished)

Overview

The Varian 1200L is a robust, high-performance triple quadrupole liquid chromatography–mass spectrometry (LC-MS/MS) system engineered for targeted quantitative analysis and structural elucidation in regulated and research laboratory environments. Operating on the principle of tandem mass spectrometry via three sequential quadrupole mass filters (Q1 → collision cell → Q3), the instrument enables highly selective detection through precursor ion scanning, product ion scanning, neutral loss scanning, selected reaction monitoring (SRM), and multiple reaction monitoring (MRM). Its 180° curved, extended-path collision cell enhances collision-induced dissociation (CID) efficiency—critical for reproducible fragmentation and high signal-to-noise ratios in complex matrices. Designed for compatibility with electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI), the 1200L delivers reliable performance across pharmaceutical QC, environmental residue testing, clinical toxicology, and metabolomics applications. This refurbished unit has undergone full functional validation at SpectraLab Scientific and meets original factory specifications for mass accuracy, scan speed, and sensitivity.

Key Features

• Triple quadrupole architecture supporting both single-stage (Q1 or Q3 MS) and tandem (Q1/Q3 MS/MS) acquisition modes
• Extended 180° bent collision cell optimized for high-efficiency CID and low-energy fragmentation control
• Mass range of 10–1500 u with scan rates up to 6000 u/s—enabling rapid dwell-time allocation in MRM methods
• Verified ESI sensitivity: ≤10 pg reserpine with S/N ≥50:1 in both SIM and MS/MS modes
• Modular LC integration: Includes dual Varian ProStar 210 solvent delivery systems, ProStar 500 column switching module, and Rainin CH-1 column heater for method flexibility
• Automated sample introduction via Varian ProStar 410 autosampler with programmable injection volume and needle wash
• Optional GC/MS interface support—enables straightforward reconfiguration for gas chromatography–mass spectrometry workflows

Sample Compatibility & Compliance

The Varian 1200L supports direct coupling to reversed-phase, HILIC, and ion-pairing LC methods with standard 2.1–4.6 mm ID columns. It is routinely deployed in laboratories adhering to GLP, GMP, and ISO/IEC 17025 frameworks. While the system predates FDA 21 CFR Part 11-compliant audit trail functionality (introduced in later-generation software platforms), its raw data acquisition and processing workflows are fully traceable when operated under documented SOPs. All refurbished units undergo comprehensive calibration verification per ASTM E2629-21 (Standard Practice for Verification of Mass Spectrometer Performance) and include full system suitability reports. Regulatory documentation—including instrument history logs, maintenance records, and test chromatograms—is provided upon request.

Software & Data Management

The system operates with the native Varian 1200/1200L MS Workstation software suite, providing method development tools for SRM/MRM transition optimization, peak integration algorithms compatible with USP <621> and ICH Q2(R2) guidelines, and batch processing for high-throughput quantitation. Raw data files (.raw) are stored in proprietary format but exportable to ASCII or mzXML for third-party processing (e.g., Skyline, OpenMS). The included P4-based acquisition PC features dedicated hardware timing control, ensuring synchronization between LC gradients and MS duty cycles. Data backup protocols follow NIST SP 800-88 Rev. 1 recommendations for media sanitization and retention.

Applications

• Pharmaceutical impurity profiling and stability-indicating assays using MRM quantification
• Residue analysis in food and environmental samples (e.g., pesticides, veterinary drugs) per EU SANTE/11312/2021 criteria
• Clinical assay development for small-molecule biomarkers (e.g., steroids, immunosuppressants) with sub-ng/mL LODs
• Metabolite identification via neutral loss and precursor ion scans in drug metabolism studies
• Method transfer from legacy Varian platforms to modern LC-MS/MS infrastructure

FAQ

Is this unit compliant with current FDA 21 CFR Part 11 requirements?
The Varian 1200L MS Workstation does not natively support electronic signatures or audit trails as defined in 21 CFR Part 11. However, it can be operated within a validated environment using procedural controls, manual sign-offs, and external data integrity management systems.
What level of technical support is included post-purchase?
SpectraLab Scientific provides 6 months of hardware warranty and remote troubleshooting assistance. On-site service contracts and application-specific method development support are available upon request.
Can the system be upgraded with modern ion sources or detectors?
While the 1200L platform accepts standard ESI/APCI sources, retrofitting with newer-generation ion optics or high-resolution detectors is not supported due to firmware and mechanical interface constraints.
Are consumables and spare parts still available?
Yes—key components including quadrupole rods, detector assemblies, vacuum pumps, and LC modules remain in production or are available through certified third-party suppliers with full traceability.
How is instrument performance verified prior to shipment?
Each unit undergoes full system qualification per IQ/OQ protocols, including mass calibration, resolution verification at m/z 556, sensitivity testing with reserpine, and LC-MS interface leak testing—all documented in a final certificate of analysis.
