D-Star - Model DDW-1O -Dual Wavelength Detector
At half the price of competitive dual wavelength HPLC UV-Vis detectors, the DDW-10 is a common sense approach to dual wavelength monitoring. The benefit to the user is dual wavelength detection at a single wavelength price. The DDW-10 is ideal for applications such as protein, peptides, and amino acid analysis including Ninhydrin amino acid derivatives. Most analyses of proteins and peptides are carried out at two wavelengths: 214 and 280nm respectively. Many investigators, however, will purchase a premium priced dual wavelength detector which offers many times the capabilities they will ever need for the analyses they require.
The development of the DDW-10 was a direct result of discussions with our customers, particularly in the bio-tech applications market. These customers told us that practically 90% of their analyses using dual wavelength detectors were performed at the same consistent 2 or 3 wavelengths. However, in order to achieve dual wavelength detection they purchased available expensive dual wavelength detectors, and in some cases even more expensive diode array instruments for routine dual wavelength analysis. Until the introduction of the D-Star DDW-10 there was no other choice.
