A mass spectrometer is often called the "ultimate truth machine", because it delivers unequivoal information about the sample, impurities and relative quantitation - far beyond the subjective spots on a TLC plate or questionable UV absorbance peaks. And we wish to make this rich information easily understandable. Data Express is the data processing software program which accomplishes the perfect balance. Easily analyze and display results, or use a wealth of software resources to mine the data for accurate decision-making, archiving or exporting. Starting with UPLC/CMS data(which the expression CMS delivers flawlessly because of fast scanning capabilities and superb sensitivity), we dive below the total ion chromatograms (TICs) to explore what is really happening.
