MD-4010/4015/4017 PDA Detector
The LC-4000 Series includes three PDA detectors. The MD-4017 is a useful replacement for a single wavelength detector, the MD-4015 is the workhorse for UV-visible detection in the range 200 to 600 nm and the MD-4010 is designed for high sensitivity and high spectral and time resolution.
The MD-4010 PDA detector offers the highest detection sensitivity, equivalent to a single wavelength detector. Making use of a 1024 element photometric diode array, the measurement wavelength range is from 190 nm to 900 nm with a resolution of 1 nm and fast spectrum acquisition rate of up to 100 spectra/sec. When used with the new temperature controlled SP type semi-micro flow cell the MD-4010 is well suited to the narrower peaks typically found with UHPLC or RHPLC separations. The MD-4010 is fitted with an internal mercury lamp for automatic wavelength calibration.
The MD-4015 PDA detector is the routine detector for conventional HPLC, RHPLC and UHPLC. The sensitivity is almost equivalent to that of the MD-4010 but only covers the wavelength range from 200 nm to 600 nm using a 512 element PDA for 1 nm resolution and with high speed 100 Hz spectrum acquisition.
The MD-4017 detector has a pricepoint comparable to a typical single wavelength detector and has been designed for the user only interested in the UV region from 200-400 nm, the resolution is excellent at 1 nm and the maximum spectrum acquisition is 20 spectra per second (20 Hz), useful for peak widths as small as 1 to 2 seconds.
When used with ChromNAV 2.0 CDS the PDA detector offers multifunctional analysis with a variety of functions such as spectral analysis, library search for peak identification, peak purity and multi-wavelength quantitation.
