Acquity Ultra Performance LC 2996 PDA Detector

Acquity Ultra Performance LC 2996 PDA Detector

Description

A photodiode-array detector for UPLC chromatographic separations, providing ultraviolet absorbance detection with spectral information for identifying and quantifying compounds. It supports analysis of trace impurities alongside higher-level components in a single separation and can be used for routine analysis, method development and compound identification.

Key Features

• Provides simultaneous 2D and 3D operation through Empower or MassLynx software.
• Uses a low-volume, light-guiding UPLC flow cell to improve light transmission efficiency.
• Provides optical and digital spectral resolution for comparing analyte spectra across ultraviolet wavelengths.
• Uses a prealigned, intelligent-technology deuterium lamp.
• Flow-cell options include analytical, high-sensitivity, high-throughput, low-dispersion, microbore and microscale configurations.

Applications

• Trace-impurity detection and quantification within chromatographic peaks.
• Compound identification through ultraviolet spectral comparison and library matching.
• UPLC method development and routine analysis where spectral information supports analyte characterisation.
• UPLC-MS detection strategies for components that are difficult to resolve by conventional HPLC-based methods.

Specifications

• Wavelength range: 190 to 500 nm.
• Wavelength accuracy: ±1 nm via an erbium filter.
• Optical resolution: 1.2 nm.
• Digital resolution: 0.6 nm/pixel to 500 nm‌ .‌ , and sampling rate: up to 80 points/s.
