HPLC with DAD and UV

Shimadzu offers the flexible photodiode array detector, SPD-M30A with minimal dispersion for fast UHPLC separations, ideal for USP compliant analog tests. It has improved accuracy in compound identification from absorbance spectra, and can perform an impurity check for all peaks. It leads the industry in deconvolution algorithms to resolve coeluting peaks. Low dispersion capillary cells and multi-wavelength settings guarantee high sensitivity analysis of trace components. A newly designed capillary cell and optical system improved signal level and reduced noise level. Stray light compensation technology and temperature control features enable precise identification, quantification, and peak purity analysis at trace levels. Utmost flexibility is guaranteed for high-speed multi-wavelength (up to 4 discrete channels) sampling range. Up to four wavelengths can be output, allowing the SPD-M30A to perform as a multi wavelength UV detector.
