SKU: WAT011740 Resolve C18 Column, 90Å, 5 µm, 3.9 mm X 300 mm, 1/pk
The non-encapped Resolve C18 column offers significantly different selectivity compared to similar HPLC packings like Nova-Pak and µBondapak. The change in chromatographic behavior is most commonly noticed with polar compounds, which are typically more retained.
The signal output per unit concentration or mass of a substance in the mobile phase entering the detector, for example, the slope of a linear calibration curve, is referred to as sensitivity. For concentration-sensitive detectors, sensitivity is sometimes defined as the ratio of peak height to analyte concentration in the peak. In mass-flow-sensitive detectors, it is the ratio of peak height to unit mass. To be a distinct performance attribute, sensitivity must be solely dependent on the chemical measurement procedure, not on scale considerations.
Many instrumental and chemical parameters influence the ability to detect (that is, qualify) or measure (that is, quantify) an analyte. In an ideal world, high-efficiency columns elute well-resolved peaks (narrow peak width with good symmetry for maximum peak height). This is in addition to the sensitivity and specificity of the detector. Both separation system interference and electronic component noise should be minimized to ensure optimal sensitivity.
