Overview
A Diode Array Detector (DAD) is an advanced optical spectrometer used in high-performance liquid chromatography. It utilizes a photodiode array to capture full UV-Vis spectra simultaneously, enabling rapid wavelength selection and spectral purity analysis without mechanical scanning.
Application
- Pharmaceuticals: Drug purity testing in HPLC systems.
- Chemical Manufacturing: Reaction monitoring and quality control.
- Environmental Labs: Water pollutant detection via LC units.
Precautions
- Operate within 15°C–30°C ambient temperature.
- Maintain relative humidity below 80% non-condensing.
- Regularly flush flow cells with deionized water to prevent clogging.
- Ensure inlet pressure does not exceed 40 MPa to avoid cell damage.
