Waters 996 PDA Detector

 

Waters 996 Detector is the highest sensitivity, most versatile HPLC Photodiode Array Detector available. The Waters 996 detector operates exclusively with Waters Empower software to provide complete spectral acquisition and results management. All performance specifications are for the 996 detector following a warm-up period of one hour.

 

Advanced Taper Beam optics insure exceptional S/N performance and the freedom from any refractive index effects needed in high sensitivity analyses. Exceptional optical resolution distinguishes between compounds and structurally similar impurities, even in disparate or trace quantities. 

 

The detector’s unmatched linearity and sensitivity (chroma-tographic and spectral) is maintained across the range of monitored wavelengths. Scan the entire wavelength range to obtain detailed spectral maps. Then look at your results from a variety of perspectives, even while a separation is under way.

 

Increase Confidence: Automatically identify peaks using the Library Match function. Assess peak homogeneity and identity using Waters unique Spectral Contrast and library match algorithms. 

Finest Spectral Details: The true 1.2 nm optical resolution and optics bench efficiency enables the combination of narrow slit width with high digital resolution into the markets only true “no-compromise” optical system. 

Easy to Set-up and Run: Due to the "no-compromise" optics design, no choices need to be made regarding chromatographic or spectral sensitivity. Turn the 996 on and run.

 

Waters 474 Fluorescence Detector

 

Description: The Waters 474 Scanning Fluorescence Detector is a high-performance unit that provides a high level of sensitivity for spectrofluorometric analysis.

 

Features:

 

The Waters 474 Scanning Fluorescence Detector includes:

 

- An optical design that maximizes sensitivity

- Microprocessor control for greater versatility and reliability

- An emission wavelength sweep function so you can obtain an emission spectrum

- An excitation wavelength sweep function so you can obtain an excitation spectrum

- An automatic second-order filter to enhance applications in the visible wavelength range

- Optional optical filters that can be installed on the flow cell for specialized measurements

- Quartz flow cell or cuvette cell, permitting measurement of ultraviolet fluorescence

- Nine-stage photomultiplier tube for amplifying the emission radiation

- Photodetector to compensate for excitation fluctuations throughout a scan

- An RS-232 port to allow connectivity to the Empower data system

 

There are three critical optical design features in the 474 detector:

 

- A highly energy-efficient optics system that does not use lenses, minimizing reflection loss

- An optics system that uses holographic concave diffraction gratings and aspherical mirrors to provide highly efficient monochromators in a compact package 

- A 150 W Xenon lamp that provides greater light energy for excitation

 

There are five critical microprocessor-based features:

 

- Operating parameters that are set using the keypad

- A multi-line liquid crystal display (LCD) that provides information on the status of the 474 detector 

- Self-diagnostic messages that are displayed on the LCD

- Digital processing that controls the entire signal processing system, assuring higher reliability and operational stability

- An auto-zero feature that provides a wide range of offset adjustment for the analog output
