Baseline: The baseline is the line drawn by the recording device representing the signal from the detector when only mo- bile phase is passing through, in the ab- sence of any solutes. It also represents the point from which calculations are often made on peaks to determine peak area or ...

The stability of the aptamers was determined by high-performance liquid chromatography (HPLC) using a Waters e2695 HPLC system (Waters Corp., Milford, MA, USA) equipped with a quaternary pump and variable wavelength detector. Chromatographic data were processed using a personal computer equipped ...
SIM mode was used to improve the sensitivity of the detector for the analytes of interest. The highest abundance ion for each analyte was typically chosen to achieve the best sensitivity. If selectivity was compromised by this choice, another less abundant ion was used. For most of the ...

For the commonly used universal detectors, UV is limited to compounds that possess a chromophore,mass spectrometry (MS) to those compounds that ionize, and refractive index (RI) detector are chromatographically inferior as they are extremely temperature sensitive and cannot be used with gradients. ...
There is a great deal of information indicating that the fastest growing detector for HPLC is the mass spectrometer. MS detectors would seem ideal for HPLC since they cover a wide class of compounds including those that are polar, have a high molecular weight, are ionic or ionizable, or ...
