UV/vis spectrophotometer for HPLC
WaveQuest Cecil Instruments

WaveQuest the CE4300 Dynamic Absorbance Detector (DAD) is an ultra high speed scanning powerful alternative to Photo Diode Array detectors. HPLC method development, purity determination, R & D and Variable Wavelength Monitoring are all possible with the highest quality. Dual wavelength monitoring and wavelength programming are also provided.

The design is based on a double beam spectro-photometer concept with ultra fast wavelength scanning over the range 190-700nm.

This dynamic scan provides UV spectra in only 200mS, previously only possible using the static optical system of a PDA detector.

Powerful signal processing software has been developed which enables very high quality "on-the-fly" scans to be triggered by eluting peaks without the peaks being degraded.

Spectral data is transferred by Cecil's DataStream software to a PC workstation where the same software offers spectral manipulation and processing, library facilities and the export of data to applications such as Excel, word etc. All data may be stored on disk.

Eluting peaks may be integrated at the same time as purity and peak identification is carried out. Quantitative evaluation and reporting is carried out by Cecil's CE4900 PowerStream software, which is combined with DataStream software.
