HORIBA QuantaMaster 8000 Series Modular Fluorescence Spectrometer

Overview

The HORIBA QuantaMaster 8000 Series is a research-grade, fully modular fluorescence spectrometer engineered for quantitative steady-state and time-resolved photoluminescence analysis across an unprecedented spectral range—from deep ultraviolet (210 nm) to extended near-infrared (5500 nm). Built upon decades of HORIBA Scientific’s expertise in time-correlated single-photon counting (TCSPC) and molecular spectroscopy—augmented by the 2014 acquisition of Photon Technology International (PTI)—the QuantaMaster 8000 integrates advanced optical architecture, high-fidelity signal detection, and deterministic temporal resolution into a single platform. Its core measurement principle relies on wavelength-selective excitation and emission detection using double- or triple-monochromator configurations with computer-controlled grating selection, enabling rigorous separation of analyte signals from background scatter and stray light. The system supports multiple lifetime methodologies—including TCSPC, Strobe-gated detection, and the proprietary Single-Shot Time-Domain (SSTD) technique—making it uniquely capable of resolving phosphorescence decays as short as 1 µs with sub-second acquisition times. Designed for compliance-critical environments, the instrument architecture supports audit-ready data handling workflows aligned with GLP and GMP practices.

• 6 independently configurable detection channels, including PMT, InGaAs, and liquid-nitrogen-cooled MCT detectors for NIR–MIR coverage
• Full automation of optical components: motorized slits, exit port selectors, filter wheels, and accessory positioning—all controlled via FelixGX
• Compact footprint (92 × 72 × 31 cm), minimizing laboratory space requirements without compromising optical performance

Sample Compatibility & Compliance

The QuantaMaster 8000 accommodates diverse sample formats—including cuvettes (standard and micro-volume), powders, thin films, fibers, and solid-state devices—through its Quadra Centric™ open-sample chamber. Temperature-controlled stages (−196 °C to +600 °C), integrating spheres, cryostats, electrochemical cells, and fiber-optic probes are supported natively and remotely operated. All hardware and software modules comply with international standards relevant to analytical instrumentation: ISO/IEC 17025 for testing laboratories, ASTM E1421 for fluorescence quantum yield measurements, and USP for pharmaceutical photostability assessment. Data integrity features—including electronic signatures, user-access logging, and full audit trails—meet FDA 21 CFR Part 11 requirements when deployed in regulated QC/QA settings.

Software & Data Management

FelixGX is the unified, Windows-based application environment for instrument control, experiment sequencing, real-time visualization, and advanced data analysis. It provides native support for steady-state spectra, excitation-emission matrices (EEMs), time-resolved decay fitting (mono- to multi-exponential, distributed lifetime models), time-resolved emission spectra (TRES), and absolute quantum yield calculations. Specialized modules include FRET efficiency quantification, carbon nanotube chirality assignment, CIE chromaticity mapping, and absorption-corrected fluorescence intensity normalization. All lifetime fitting algorithms are fully open—no licensing restrictions apply to parameter constraints, residual analysis, or global fitting across datasets. Raw photon arrival timestamps (for TCSPC mode) and analog waveforms (for Strobe/SSTD) are stored in vendor-neutral HDF5 format, ensuring long-term archival compatibility and third-party interoperability.

Applications

The QuantaMaster 8000 serves as a primary characterization tool in academic, industrial, and governmental research laboratories focused on photophysics, materials science, life sciences, and energy conversion. Typical use cases include: quantitative luminescence quantum yield determination of OLED emitters and perovskite nanocrystals; time-resolved studies of charge-transfer states in photocatalysts; phosphorescence lifetime mapping of triplet-harvesting thermally activated delayed fluorescence (TADF) materials; FRET-based conformational dynamics in labeled biomolecules; upconversion nanoparticle excitation cross-section profiling; and microsecond-to-millisecond phosphorescence kinetics in metal–organic frameworks (MOFs) and lanthanide-doped glasses. Its NIR extension to 5500 nm enables direct interrogation of vibrational overtones and low-energy electronic transitions inaccessible to conventional fluorimeters.

FAQ

What lifetime techniques does the QuantaMaster 8000 support?
TCSPC, Strobe-gated detection, and the proprietary Single-Shot Time-Domain (SSTD) method—all operable across the full 210–5500 nm range.
Can the system perform absolute quantum yield measurements in the NIR?
Yes—when equipped with an integrating sphere and calibrated NIR reference standards, the system complies with ASTM E1421 and enables absolute quantum yield quantification up to 1700 nm (with optional extension to 5500 nm via MCT detection).
Is FelixGX compliant with 21 CFR Part 11?
Yes—when configured with role-based user accounts, electronic signatures, and audit-trail logging enabled, FelixGX meets FDA regulatory requirements for electronic records and signatures.
How many gratings can be installed simultaneously?
The triple-grating turret holds three gratings at once; switching is fully automated and software-controlled without manual intervention.
Does the system support coupling to a fluorescence microscope?
Yes—the open optical architecture and standardized C-mount interfaces allow direct integration with major commercial inverted and upright microscopes for confocal microspectroscopy and ratiometric Ca²⁺ imaging.
