AGILENT CARY ECLIPSE FLUORESCENCE SPECTROPHOTOMETER

Significance of the Topic

Fluorescence spectroscopy is a powerful analytical technique widely used in chemical, environmental, and life science applications due to its high sensitivity and selectivity. The ability to detect trace amounts of fluorescent species and to measure rapid kinetic events makes fluorescence spectrophotometers essential tools for research, quality control, and process monitoring.

Objectives and Study Overview

This summary reviews the capabilities of the Agilent Cary Eclipse Fluorescence Spectrophotometer. The aim is to present its key performance features, methodological flexibility, and practical applications to help laboratories and researchers choose an optimal instrument for their analytical challenges.

Used Instrumentation

The instrument under discussion is the Agilent Cary Eclipse Fluorescence Spectrophotometer, designed for:

• Room-light immune measurements with lid open, closed, or via fiber optics
• Multiple detection modes: fluorescence, phosphorescence, chemiluminescence, and bioluminescence
• Optional fiber optic probes for remote or in situ sampling
• Microplate reader configuration for high-throughput assays

Methodology and Instrumentation

Measurement methodology combines fast scanning, flexible sampling accessories, and precise temperature control:

• Excitation and emission scanning at rates up to 24 000 nm/min for full-range spectra in under 3 seconds
• Data point collection at up to 80 points/s for sub-second kinetic studies
• Temperature-controlled sample probes to prevent photobleaching and to study thermal stability
• Fiber optic sampling to analyze solids, high-temperature, hazardous, or remote samples

Main Results and Discussion

Performance highlights include:

• Lamp lifetime exceeding 3 billion flashes, typically lasting 10 years to reduce operating costs
• Picomolar detection limits in standard and micro-cuvettes
• Switcher control for rapid mode changes among fluorescence, phosphorescence, chemiluminescence, and bioluminescence
• Application flexibility demonstrated across chemical, environmental, and life science case studies

Discussion points emphasize the balance between sensitivity, speed, and cost-effectiveness. The robust design and fiber optic options extend analysis beyond conventional cuvette-based measurements, addressing challenging sample matrices and real-time monitoring needs.
