LC-4000 Series PDA Detectors from JASCO

The LC-4000 Series includes three PDA detectors.

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 190 nm to 900 nm 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 200 nm to 650 nm using a 512 element PDA for 1nm resolution, and with high speed 100 Hz spectral acquisition.

The MD-4017 uses a CMOS detector covering the UV region from 200-400nm; with 1nm resolution and up to 20Hz spectrum acquisition; useful for peak widths as small as 1 – 2 seconds.
