Waters 1525 Binary Pump with 2487 (UV/Vis) Detector & 717 Plus Autosampler
2487 Dual Wave Absorbance (UV/Vis) Detector
- Advanced Programmability
- Dual Wavelength Capability
- Unmatched Signal-To-Noise Performance
- Reduced Optical Bandwidth
- Exceptional Linearity
In the dual wavelength modes, it has more capability than a single wavelength detector for increasing sensitivity with MaxPlot and qualitative information from RatioPlot.
MaxPlot: The absorbance spectra of different compounds have different lambda maxima. The greatest absorbance will be obtained at the lambda maximum for each compound. MaxPlot is a dual wavelength feature to maximize sensitivity at two wavelengths in a single chromatogram. The user chooses two wavelengths, one for each channel of the Waters 2487 and sets the output of one channel for MaxPlot. As the detector monitors a chromatogram, the highest absorbance from either wavelength is outputted as MaxPlot. The figure below illustrates this feature. The MaxPlot is more sensitive than either 242 or 270 nm for detecting all three analytes.
RatioPlot: The Waters 2487 can plot the ratio of two wavelengths that are chosen by the user on channels A and B. The two wavelengths are two points on the compounds' spectra. When the RatioPlot is flat at the top, the ratio of the two absorbances is constant. This constant ratio suggests peak homogeneity.
