The LC-4000 Series includes three PDA detectors. The MD-4017 is a simple replacement for a single wavelength detector, the MD-4015 is the workhorse for UV-Visible detection in the range 200 to 650 nm and the MD-4010 has a wide wavelength range.
The MD-4010 PDA detector has high sensitivity, comparable to a single wavelength detector. It uses a 1024 element photometric diode array, with measurement wavelength range from 190nm to 900nm and resolution of 1 nm. Fast spectral acquisition rate of up to 100 spectra/sec. The temperature controlled SP type semi-micro flow cell is used narrow peaks typically found with fast UHPLC or RHPLC separations. An integrated mercury lamp is used for automatic wavelength calibration and validation.

The MD-4015 PDA detector is similar to the MD-4010 with equivalent sensitivity, covering the wavelength range from 200nm to 650nm using a 512 element PDA for 1 nm resolution, and with high speed 100Hz spectral acquisition.
