Anyeep TQ9120 Triple Quadrupole Liquid Chromatography Tandem Mass Spectrometer (LC-MS/MS)

Overview

The Anyeep TQ9120 is a high-performance triple quadrupole liquid chromatography tandem mass spectrometer (LC-MS/MS) engineered for demanding quantitative and confirmatory analyses in regulated and research laboratories. Based on proven atmospheric pressure ionization (API) principles—including electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI)—the system employs a robust dual-quadrupole mass filtering architecture followed by collision-induced dissociation (CID) in a pressurized RF-only collision cell, enabling highly selective multiple reaction monitoring (MRM) with exceptional signal-to-noise ratio. Designed as a next-generation evolution of the TQ9100 platform, the TQ9120 integrates hardware refinements and software enhancements to deliver improved sensitivity, long-term stability, and expanded dynamic range—key performance criteria for trace-level quantification in complex matrices.

Key Features

• Optimized high-efficiency ion source featuring an advanced desolvation heater and re-engineered gas flow dynamics, resulting in enhanced ionization efficiency and reduced signal drift across extended run times.
• Upgraded Multi-Stage Ion Focusing (MIF) transmission optics, delivering up to 10× higher ion transmission efficiency from source to detector compared to prior-generation designs.
• Fully integrated GLP-compliant audit trail functionality, supporting full traceability of method parameters, instrument settings, calibration records, and data processing events per FDA 21 CFR Part 11 requirements.
• Intelligent acquisition software with scheduled MRM (sMRM) scheduling, automated tuning and optimization routines, and built-in regulatory databases—including Chinese GB pesticide residue maximum residue limits (MRLs)—for automated compliance flagging and report generation.
• Modular vacuum architecture with dual-stage turbomolecular pumping and real-time pressure monitoring, ensuring stable operation under varying load conditions and extended maintenance intervals.
• Ruggedized front-end design compatible with standard HPLC/UHPLC systems, including compatibility with common column formats (1.0–4.6 mm ID), flow rates (50 µL/min–2 mL/min), and mobile phase chemistries (aqueous/organic gradients, volatile buffers).

Sample Compatibility & Compliance

The TQ9120 supports broad sample applicability across small-molecule analysis, targeted metabolomics, residue testing, and clinical biomarker quantification. It is routinely deployed in laboratories performing analyses aligned with ISO/IEC 17025, AOAC Official Methods®, and national food safety standards (e.g., GB 23200 series). The system meets essential hardware and software prerequisites for GxP environments, including secure user authentication, electronic signatures, version-controlled method storage, and immutable audit logs. All firmware and control software are validated for use in quality-controlled workflows subject to GLP or GMP audits.

Software & Data Management

The proprietary Anyeep MSControl Suite provides a unified interface for instrument control, data acquisition, processing, and reporting. It supports raw data export in open formats (mzML, .csv) and integrates with third-party platforms including Waters MassLynx, Thermo Compound Discoverer, and commercial LIMS solutions via standardized APIs. Data integrity safeguards include automatic backup, time-stamped metadata embedding, and configurable retention policies. The software implements role-based access control (RBAC), session timeout enforcement, and encrypted local database storage compliant with ISO 27001 information security guidelines.

Applications

• Food safety testing: Quantitative screening of pesticides, veterinary drug residues, mycotoxins, and environmental contaminants in fruits, vegetables, dairy, and meat products.
• Environmental analysis: Detection and quantification of pharmaceuticals, endocrine disruptors, flame retardants, and PFAS compounds in wastewater, soil extracts, and biota samples.
• Clinical research: Targeted quantification of steroids, vitamins, therapeutic drugs, and endogenous metabolites in plasma, serum, urine, and dried blood spots.
• Pharmaceutical development: Bioanalytical support for PK/PD studies, impurity profiling, and stability-indicating assays in accordance with ICH M10 guidance.
• Proteomics: Selected reaction monitoring (SRM) and parallel reaction monitoring (PRM)-enabled quantification of post-translational modifications and low-abundance peptides in complex digests.

FAQ

What ionization sources are supported on the TQ9120?
The system is equipped with dual ESI/APCI sources, both fully switchable and independently controllable without venting the vacuum system.
Is the TQ9120 compliant with FDA 21 CFR Part 11?
Yes—the instrument control software includes full electronic signature capability, audit trail logging, and secure user management modules validated for regulated submissions.
Can the TQ9120 be integrated into existing laboratory informatics infrastructure?
Yes—it supports standard communication protocols (TCP/IP, OPC UA) and offers native export to LIMS and ELN systems via configurable webhooks and file-based triggers.
What is the typical detection limit for small molecules under MRM mode?
Detection limits are matrix- and compound-dependent; typical sub-pg/mL LODs are achievable for optimized analytes in clean solvent standards, consistent with industry benchmarks for modern triple quadrupole platforms.
Does the system support automated method development?
Yes—integrated tools include intelligent precursor/product ion selection, collision energy ramping, and dwell time optimization based on peak intensity and dwell count heuristics.
