See what's really in your sample - Measurement modes available on QIAxpert

With QIAxpert – QIAxpert spectrophotometer offers two measurement modes to accom- modate all nucleic acid sampe types, whether pure or complex. Unlike other spectrophotometers that simply give an overview of all absorb- ing components, the revolutionary QIAxpert unmixes the spectra using unique protocols thus discriminating between your molecules of interest. 0 2 4 6 8 10 12 14 230 260 290 320 Wavelength (nm) Absorbance (10mm) 350 380 410 440 Total absorbance spectrum Target molecule (DNA or RNA) Impurities Residues Background 0 2 4 6 8 10 12 14 230 260 290 320 Wavelength (nm) Absorbance (10mm) 350 380 410 440 Total absorbance spectrum (total nucleic acids) Background Classic Spectrophotometry For pure samples Spectral profiling For pure & complex samples Measurement of absorbance at defined wavelengths for calculating nucleic acid concentration and providing estimation on contamination level through ratio calculation. Content profiling by unmixing of spectra and fitting of reference sample and buffer components; enabling correct discrimination between DNA, RNA, and impurities. Quantity! Quantity & Quality!
