Agilent 1260 Infinity II G7121B Multi-Signal Fluorescence Detector for HPLC
Product Description
The Agilent 1260 Infinity II G7121B FLD Detector is a high-performance multi-signal fluorescence detector designed for advanced HPLC workflows and detailed spectral analysis in fields such as biotechnology, molecular diagnostics, and bioprocessing. Equipped with a xenon flash lamp light source (20 W normal mode, 5 W economy mode) offering a 4000-hour lifetime, it supports excitation and emission wavelength scanning from 200 nm to 1200 nm, critical for fluorescence applications requiring a broad spectral range.
Key technical features include:
- Multi-signal capability with rapid on-line scanning and advanced spectral data analysis, allowing flexible single or dual wavelength operation.
- Fast spectrum acquisition with scan speeds as low as 28 ms per datapoint and high data rates up to 148 Hz for efficient fluorescence data collection.
- Precision wavelength repeatability of ±0.2 nm and accuracy within ±3 nm, essential for reproducible analytical measurements.
- An 8 μL standard flow cell rated to 20 bar (2 MPa) pressure maximum supports high-pressure liquid chromatography setups.
- Integrated spectral storage with adjustable step size from 1 to 20 nm for customizable spectral resolution.
- Dedicated safety features including automated leak detection, safe leak handling, and system shutdown signals to ensure reliable operation in GLP-compliant environments.
- Multiple communication interfaces (CAN, USB, ERI signal integration) enabling seamless integration into laboratory information management systems.
This fluorescence detector is ideal for researchers and professionals engaged in biotechnology and synthetic biology workflows, where precise fluorescence detection supports gene editing validation, biomanufacturing quality control, and molecular cloning workflows. Its rapid online scanning and multi-signal detection capabilities facilitate fluorescence analysis in complex biological samples, making it a popular choice among molecular biology, clinical diagnostics, and bioprocessing laboratories.
Built for durability and ease of maintenance, the Agilent 1260 Infinity II FLD Detector also provides real-time instrument tracking, early maintenance alerts, and wavelength accuracy verification, ensuring dependable performance in demanding analytical and biotechnological environments.
