SCIEX Triple Quad™ 5500+ LC-MS/MS System – QTRAP® Ready

Overview

The SCIEX Triple Quad™ 5500+ LC-MS/MS System – QTRAP® Ready is a high-performance, modular tandem mass spectrometer engineered for robust quantitative and qualitative analysis in regulated and discovery-oriented laboratories. Built upon SCIEX’s legacy of over five decades of mass spectrometry innovation, this system combines the proven reliability of triple quadrupole (QqQ) architecture with native readiness for QTRAP® functionality—enabling seamless transition between targeted quantitation and information-dependent acquisition (IDA) workflows without hardware modification. Its core operational principle relies on electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI) coupled to liquid chromatography, followed by mass-selective fragmentation in Q2 and detection in Q3. The system supports multiple scan modes—including MRM, MRM³, Enhanced MS, Enhanced Resolution, and MRM–IDA–EPI—each optimized for specific analytical challenges in complex matrices.

Key Features

• QTRAP® Ready architecture: Enables dual-mode operation—triple quadrupole quantitation (MRM) and linear ion trap (LIT)-based qualitative analysis—via software activation, eliminating the need for separate instruments.
• MRM³ capability: Provides third-generation fragmentation for selective quantitation in high-background environments where conventional MRM suffers from interferences.
• MRM–IDA–EPI workflow: Integrates scheduled MRM acquisition with real-time, intelligent data-dependent enhancement product ion scanning—delivering structural confirmation and spectral fingerprinting alongside quantitative results.
• Enhanced MS mode: Delivers high-sensitivity full-scan spectra for untargeted screening and unknown compound detection at sub-picomolar levels.
• Enhanced Resolution mode: Optimizes peak shape and m/z assignment fidelity for improved charge state determination and nominal mass validation.
• Modular front-end compatibility: Fully integrated with SCIEX’s portfolio of LC systems—from nanoLC and microLC to UHPLC—and SelexION® differential ion mobility technology for enhanced isomeric separation.

Sample Compatibility & Compliance

The 5500+ system accommodates a broad range of sample types across biological fluids (plasma, serum, urine), tissue extracts, food homogenates, environmental water/soil extracts, forensic toxicology specimens, and biopharmaceutical digests. It meets essential regulatory expectations for GLP, GMP, and CLIA-compliant environments through built-in audit trail functionality, user access controls, electronic signature support, and alignment with FDA 21 CFR Part 11 requirements when deployed with SCIEX OS software and appropriate IT infrastructure. Method validation workflows align with ICH guidelines and ASTM D7869-22 (for environmental analysis) and USP (for pharmaceutical applications).

Software & Data Management

Controlled exclusively via SCIEX OS software, the system provides a unified interface for instrument method development, acquisition scheduling, real-time monitoring, and post-run processing. Data files adhere to open vendor-neutral formats (e.g., .wiff) and are compatible with third-party quantitation platforms including MultiQuant™, MasterView™, and PeakView™. All raw data and processing parameters are stored with time-stamped metadata, supporting traceability and reprocessing. Audit trails record operator actions, method changes, and calibration events—critical for regulatory submissions and internal quality audits. Integration with LIMS and ELN systems is supported via standard APIs and ODBC connectivity.

Applications

• Clinical research and diagnostics: Quantitative analysis of biomarkers, hormones, vitamins, and therapeutic drugs in human matrices.
• Pharmaceutical development: PK/PD studies, metabolite identification, impurity profiling, and stability-indicating assays.
• Food safety: Detection and quantification of pesticides, mycotoxins, veterinary drug residues, and allergens.
• Environmental monitoring: Analysis of persistent organic pollutants (POPs), PFAS, pharmaceuticals in wastewater, and endocrine disruptors in surface water.
• Forensic toxicology: Multi-analyte screening and confirmation of drugs of abuse, novel psychoactive substances (NPS), and synthetic opioids.
• Life sciences: Targeted proteomics (SRM/MRM), lipidomics, and small-molecule pathway analysis in cell lysates and tissue sections.

FAQ

What does “QTRAP® Ready” mean?
It indicates that the instrument ships with hardware identical to a QTRAP system and requires only a software license activation to unlock linear ion trap capabilities—no physical upgrade or service visit is needed.
Can MRM and EPI be acquired simultaneously in a single run?
Yes—via the MRM–IDA–EPI mode, the system performs scheduled MRM transitions and triggers EPI scans in real time based on predefined criteria such as intensity threshold or retention time window.
Is the 5500+ compatible with non-SCIEX LC systems?
Yes—it supports standard analog and digital interfaces (e.g., TTL, RS-232, Ethernet) for synchronization with third-party HPLC/UHPLC systems, though optimal performance and full feature integration are achieved with SCIEX LC platforms.
Does the system support high-resolution accurate-mass (HRAM) analysis?
No—the 5500+ is a unit-mass resolution triple quadrupole platform; HRAM capabilities require a QTOF or X500B system within the SCIEX portfolio.
What regulatory documentation is provided with the system?
Each installation includes a Factory Acceptance Test (FAT) report, IQ/OQ documentation templates compliant with ISO/IEC 17025 and ASTM E2500, and a comprehensive instrument qualification package aligned with GAMP 5 principles.
