Shimadzu SPD-M30A High Performance Liquid Chromatography Photodiode Array detector

Thursday, 01 November, 2012 | Supplied by: Shimadzu Scientific Instruments (Oceania) Pty Ltd


The Shimadzu SPD-M30A High Performance Liquid Chromatography (HPLC) Photodiode Array (PDA) detector provides users with a high level of sensitivity and stability, with a very good specification for noise level of ±0.2 x 10-6 AU.

In addition to low noise, the detector also boasts a low drift of 0.5 mAU/h, allowing confidence in stable baselines even over long batch runs. These gains have been achieved with low-noise electronics, temperature-controlled optics, including flow cells, and a high brilliance optical system.

A 1024 element CMOS diode array realises improved spectral resolution and low dark current. Faster electronics and diode array response allows data sampling rates of up to 200 Hz, more than fast enough for the narrowest UHPLC peaks. A range of cells, including capillary and low volume, gives users a cell choice for a wide range of applications, including cells for minimised peak dispersion in UHPLC and micro-LC applications. This results in greater sensitivity and improved signal-to-noise performance by minimising peak band dispersion.

The product also incorporates i-PDA (intelligent peak deconvolution analysis) technology. This facilitates the effective separation of challenging overlapped peaks, the quantitation of unseparated peaks and an enhanced peak purity function. Using the derivative spectrum, overlapping analyte peaks can be deconvoluted, allowing their convenient integration and quantitation.
