Powerful signal processing software enables
very high quality ‘on-the-fly’ scans to be triggered
by eluting peaks without peak degradation. Eluting peaks may be
integrated by PowerStream software at the same time as purity and
identification are carried out.
Spectral data is transferred by DataStream software to a PC workstation
for spectral manipulation and processing. The software offers library
facilities and the export of data. All data may be stored on disk.
Universal UV/Visible Detector
WaveQuest the ultra fast scanning Dynamic Absorbance Detector (DAD)
is a major advance in UV-visible detector design, offering the capabilities
of a Photo Diode Array (PDA) detector with greatly improved performance
when used for chromatogram monitoring.
Very high speed scanning of eluting peaks, “on the fly”,
makes purity checks, the determination of optimum monitoring wavelengths
for unfamiliar peaks (lambda max scans), and compound identification
of peaks using library spectra all possible with considerable cost
saving.
One Detector Covers All UV Applications
A single beam Photodiode Array Detector (PDA), used for method
development and R & D, will often be replaced by a dual beam
UV variable wavelength detector for routine monitoring, when the
developed method is adopted, because of the poor drift performance
of single beam PDA detectors. Their performance can be as much as
20 times worse. The Dynamic Absorbance Detector has a double beam
optical system with very high all round performance and the lowest
drift available.
The CE4300 may therefore be used for method development, purity
determination, etc. and also as a high performance UV detector for
variable wavelength monitoring.
WaveQuest, which is less expensive than a PDA detector, therefore
has a double cost advantage. |
