Waters® 2998 Photodiode Array Detector (PDA) for Alliance HPLC Systems with Low-dispersion Analytical Flow Cell Included

Product Number: 176017006

Ultimate chromatographic sensitivity in photodiode array detection

Adding spectral conformation to your absorbance detection while maintaining high sensitivity and a wide linear dynamic range can be a challenge. The Waters 2998 Photodiode Array (PDA) Detector is designed to do just that while complementing your LC and LC-MS systems. 

The uniquely integrated software and optics innovations of the 2998 PDA Detector deliver no-compromise chromatographic and spectral sensitivity and noise specification as low as 10 μAU. For routine analyses, the 2998 PDA Detector is reliable and easy-to-use, with enhanced software control for simultaneous 2D and 3D operation with either Empower or MassLynx Software – making it the ideal detector for any lab application, from compound identification to method development.

Overview

• Enhanced software control provides flexibility for simultaneous 2D and 3D operation with either Empower or MassLynx Software
• High-quality spectral resolution by operating at a fixed optical resolution of 1.2 nm
• Capable of determining spectral homogeneity, yielding confidence in method specificity

Recommended Use: Ideal for spectral conformation in absorbance detection for any lab application, from compound identification to method development.

Superior linearity

The 2998 PDA Detector offers more than 4.5 orders of linear dynamic range allowing for simultaneous quantification of high-, and low-level components within a single chromatographic separation. Detector sensitivity and spectral resolution can be optimized by adjusting the digital resolution

Wide linear dynamic range is demonstrated by the linearity plot of propyl paraben at 257 nm.

Reliable co-elution detection

The 2998 PDA Detector combined with Empower software employs powerful capabilities for determining spectral homogeneity, yielding confidence in method specificity. The 2998 PDA Detector is compatible with Empower and MassLynx setup, status monitoring, and diagnostics that are easily accessible through the software’s intuitive console and easy-to-learn interface.

Spectral analysis algorithms can aid in the assessment of peak purity. When low levels of an impurity were spiked into a sample as shown in this lidocaine example, the spectral analysis software was able to detect the impurity at levels as low as 0.1%.

Optical and digital resolution and definitive compound identification

The 2998 PDA Detector operates at a fixed optical resolution of 1.2 nm, providing high-quality spectral resolution. The low detector noise performance allows you to operate at maximum digital resolution and not sacrifice linearity.
Distinguishing between compounds is also critical for your lab. While most PDA detectors can distinguish between compounds possessing comparatively large spectral differences, the 2998 PDA Detector can differentiate between the spectra of closely related compounds.

Spectral analysis algorithms can distinguish closely related compounds, as shown in this barbiturates example, providing reliable library matching.
