SPD-20A/AV Prominence HPLC UV-Vis Detectors from Shimadzu


The SPD-20A/20AV UV-Vis detectors offer an exceptional level of sensitivity and stability, with a noise level of 0.5×10-5 AU max. One mode of the SPD-20AV allows both the deuterium and tungsten lamps to be lit simultaneously, enabling high-sensitivity wavelength-programming detection for ultraviolet light and the entire visible-light range.


Greater Baseline Stability
Supplied as standard, a temperature-controlled flow cell eliminates inconsistencies caused by changes in absorbance due to shifts in room temperature. This helps increase the baseline stability and the analysis reliability.

Superior Linearity - 2.5AU
Using newly developed signal processing technology, the stray-light correction function has been enhanced, and the linearity has been improved. This expanded linearity combines with various noise-reduction technologies to provide users with a wide dynamic range and allow for the analysis of your target compound and minor impurities in a single run.

Internal Validation Protocol
The incorporation of a low-pressure mercury lamp for wavelength calibration ensures simple calibration in the ultraviolet region.

Dual-Wavelength Measurement
Monitor two components in the UV or VIS range simultaneously.

Simultaneous D2 and W lamp Illumination
Available with the SPD-20AV, users can eliminate warm-up time and baseline disturbances during wavelength programming between the UV and Visible range. With both lamps lit, high-sensitivity analysis throughout the full wavelength spectrum is ensured.
