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

Model 3300 ELSD is designed for use with High Performance Liquid Chromatography (HPLC) systems to analyze any sample compound that has sufficiently lower volatility than the mobile phase. Some of its possible application areas include carbohydrates, pharmaceuticals, lipids, triglycerides, underivatized fatty and amino acids, polymers, surfactants, nutraceuticals, and combinatorial libraries. Evaporative light scattering detection eliminates common problems associated with other HPLC detectors. Refractive Index (RI) detectors can be complicated by solvent front interferences, baseline instability, and gradient incompatibility. RI detectors can also have a less sensitive response than ELSD. Low-wavelength UV can suffer baseline drift with steep gradients and also requires that the analyte contains a chromophore. ELSD does not have these limitations. It can achieve stable baselines with multisolvent gradients for improved resolution and faster separations. Also, since ELSD response does not depend on the sample’s optical characteristics, the sample does not require a chromophore or fluorophore for detection.

Upgraded to IIu and Added Violet laser in 2014

The new BD FACSAria II cell sorter improves ease of use, flexibility, and aseptic capability to make it the best choice for consistent results in sorting across a broad range of applications. The heart of this cell sorting revolution is the true fixed-alignment flow cell, gel-coupled to the collection optics. Fixed alignment minimizes startup time and improves reproducibility. Gel coupling to the objective lens improves collection efficiency and increases the sensitivity and resolution needed for multicolor applications.

The BD FACSAria II cell sorter advances cell sorting with multiple improvements. A new fluidics design improves aseptic setup and cleaning. New nozzle sizes enable a wide range of particles to be sorted. Software improvements dramatically cut the time spent on cytometer setup, adjustment, and maintenance.

The BD FACSAria II cell sorter also sets a new standard for ease of use to improve both workflow and productivity. A new nozzle design allows for reproducible insertions. A new universal sort tube collection mount makes it easier to insert and remove tube holders. Software wizards and automation simplify aseptic sort setup, drop-delay determination, and clog detection. Compatibility with BD digital analyzers makes it easier to move from analysis to cell sorting.
