The Waters 2475 Fluorescence Detector offers unsurpassed sensitivity for quantifying low concentrations of target compounds, whether naturally fluorescent or derivatized with a fluorescent tag. The 2475 FLR Detector sets the standard for fluorescence method development with 3D and “on-the-fly” spectral scanning for determining the optimal emission and excitation wavelengths, and has the ability to monitor up to four independent wavelength pairs.

Features:

• Innovative axially illuminated flow cell designed for less dispersion, less stray light, less volume, and more pathlength for maximum sensitivity
• Three-dimensional spectral scanning for faster method development and optimization, and enhanced peak identification
• Single or multi-channel operation monitors fluorescence at one or more discrete wavelength pairs
• Low noise performance - Less stray light due to orthogonal optics and the use of mirrors, not lenses, minimize scatter
• Multiple detection modes - 2D, 3D, and on-the-fly spectral scanning – can greatly reduce the time needed to develop fluorescence detection methods by quickly determining wavelength maxima
• Integral erbium calibration reference – ensures wavelength accuracy
• Normalized emission units for better bench-to-bench reproducibility

The Agilent/HP 6890N GC features electronic pneumatic control of all gas pressures and flows. On-board sensors automatically compensate for ambient temperature changes and barometric pressure differences to routinely achieve more accurate and reproducible results. EPC reduces re-calibration frequency and improves laboratory productivity. Designed to work seamlessly with the 6890N, the included 7683 Autosampler connects without a controller box or multiple power cords/outlets, and is packed with features including Agilent’s fast-injection technology.

Includes:

• FID Detectors (Flame Ionization Detectors) OPtional
• 7683 Autosampler (100 Vial Capacity)
• Computer Loaded with Chemstation Software
• Manuals and Cables

Features:

• Electronic Pressure Control on detector and injector
• Ambient temperature +4 °C to 450 °C
• Temperature set point resolution: 1 °C
• Supports 6 oven ramps with 7 plateaus, Negative ramps are allowed
• Overview: Laboratories worldwide are looking for a GC solution that delivers reliability, performance, and reproducible results, And nothing produces these benefits like the Agilent 6890N Network GC. By integrating leading-edge technologies with an emphasis on quality manufacturing processes, the 6890N will bring a work ethic to your laboratory that’s matched only by your own.
• Accomplish more with networking abilities

• Lets you share business and scientific data easily within a laboratory and across sites for fast and informed decision making.
• Incorporates local area network (LAN) technology as a standard feature, which makes it easy to link communication and control of multiple analytical instruments. With networking, you can work smarter, faster, and more economically.

• Increased Laboratory Efficiency: Clock-time programming allows you to set up runs for unattended operation whenever you want. The system can be ready to work when you get to your laboratory. Pre-run and post-run commands automatically prepare the system for the next sample.
• Decreased Calibration Time: You can manually enter existing calibration data and make a run with just one standard peak. The system can normalize the calibration table for you, allowing you to cut calibration time and avoid re-running your calibration standards.
• High Sample Throughput: The 6890N network GC system is already set up for the Agilent 7683 automatic liquid sampler, enabling fast and easy installation. Single or dual injectors, equipped with either an 8-sample turret or a 100-vial sample tray, allow unattended operation. Using the 11-vial transfer turret with the tray and the solvent saving mode, you have enough solvent to run unattended eight times longer than before.
• Minimal Rework: The Agilent 6890N network GC system is the only GC system that automatically selects the optimum pressure-control mode for split and splitless analyses. Forward-pressure control is best for splitless injections. Along with a large inlet liner volume and pressure-pulse operation, this mode reduces discrimination, sample degradation, and sample loss caused by liner overload while maximizing sensitivity. For split injections, the system automatically selects back-pressure control for linear split ratios over the entire usable split-ratio range and over wide column flow and pressure ranges. This reduces sample preparation and increases reproducibility and accuracy. Automatic switching between forward-and back-pressure modes yields optimal results in less time and with less effort.
