Ultrafluor Scanning Fluorescence Detector

An Advanced Technology Luminescence UV/Vis Detector

The Ultrafluor Fluorescence Detector is a highly sensitive, scanning fluorescence detector for liquid chromatography. Its dual monochromator design provides exceptional optical performance and operational flexibility for routine and trace analyses.

High Performance

An improved optical design provides exceptional performance. High-efficiency holographic diffraction gratings are optimized for high sensitivity at both lower and higher excitation wavelengths.

Customize your selectivity by choosing one of three spectral bandwidths. The pulsed xenon lamp provides a high energy level across the entire UV/Vis spectrum and produces no harmful ozone. Fluctuations in lamp intensity are automatically maintained and corrected to reduce noise and drift.

Quantitative accuracy and precision are greatly enhanced by the use of 20-bit digital electronics, producing a wider dynamic range. The electronics design allows emission monitoring of fluorescence, phosphorescence, and chemiluminescence.

Improved Laboratory Productivity

The Ultrafluor makes your job easier. Time programming of the Ex and Em wavelengths lets you optimize sensitivity and selectivity. Automatic, real-time scanning of eluting peaks helps you identify optimum wavelengths. No more time-consuming manual stop-flow techniques.

Saves Setup Time

Create up to four user files with ten timelines each for fast, easy wavelength changes. All files can be linked with the built-in queue.

A unique feature allows the emission data of any one of up to sixty stored spectra to be displayed on the LCD or played back to an external data collection device.

The signal response can be normalized to any compound of interest, or a preset factory response factor can be used. This provides consistent unit-to-unit response.

Easy Access and Maintenance

The lamp and flow cell are pre-aligned and easily accessible from the front of the instrument. Exchange or service is quick and easy. A separate lamp and flow cell housing assure quick maintenance.

Flow Cell

The Ultrafluor includes a biocompatible flow cell with 8µl illuminated volume.
