prominence Photodiode Array Detector

The SPD-M20A is the newest product out of a long experience (since 1982) developing photodiodearray detectors. Offering a very low baseline noise of less than 0.35 x 10-5 AU it is comparable or rather more sensitive as common UV detectors. The SPD-M10A is supposed to be the ideal tool for spectral identification and library searches in trace analysis by an optical resolution of 1.2 nm and spectra range of 190-800nm. Variable slit width (1.2 or 8 nm) allows an adaptation according to the application of use. Fast Scan periods and digital filter of higher order lead to a fast detector response and a high data collecting frequency (40Hz).
The SPD-M20A can be used for applications from the micro-LC up to preparative LC by changing the flow cell. The thermostated flow cell stabilizes the baseline and avoid temperature depend effect in eluents which absorbance is temperature dependent. As for an multi-wavelength UV detector, the SPD-M20A offers a 4 channel analogue outlet. The 4 channels can be imported to other data processing system or can be used for as triggers for fraction collection.

The prominence PDA detector communicates with the network / PC via an Ethernet interface, and is controlled by LabSolution software. The software package allows beside the standard data processing features and instrument control for complete prominence HPLC systems peak purity calculation, library searches and flexible reporting. The integrated web-server allows easy access to the main parameters with Microsoft Internet Explorer®.

Maintenance work is minimised by simple access to the detector cell and lamps from the front of the instrument. pre-adjusted D2 Lamps avoid time consuming adjustments of the instrument after lamp exchange. The software supports wavelength tests by inbuilt Holmium filter, energy test for optimisation of the data acquisition and logbook functions in order to meet GLP/GMP requirements.
