Agilent 1200 Multiple Wavelength Detector (MWD)

Agilent 1200 Multiple Wavelength Detector (MWD)

The Agilent 1200 Series MWD multiple wavelength detector allows a wide range of wavelengths from low UV to the visible range. The diode-array based dual lamp design provides high sensitivity for trace-level quantification. Simultaneously compounds of interest can be quantified and impurities are monitored at additional wavelengths. It is recommended for the pharmaceutical QA/QC laboratory, bioscience applications (proteins, DNA) and as a general purpose UV detector for routine work. The temperature management system ensures optimum baseline stability even under rough ambient conditions.
