Dec 1, 2005 · John V. Hinshaw Although these ionization detectors share several features, their implementations differ significantly. Detector performance characteristics (sensitivity, minimum detectable quantity, linearity, and selectivity) are affected strongly by the type of ionization mechanism, the internal electrode arrangement, and the electronics.

Practical advice, tutorials, and peer-reviewed research on liquid chromatography (HPLC), gas chromatography (GC), mass spectrometry (MS) and related techniques.

Feb 1, 2009 · The concept of the limit of detection (LOD) has been, and still is, one of the most controversial in analytical chemistry. The multiple definitions and calculation methods proposed have contributed to this situation. Although in the last years, several international organizations, such as ISO or IUPAC, have tried to reach a consensus in their definitions and have issued guidelines for the ...

Jul 1, 2013 · where gradient time (t G) is in minutes, S is a shape factor and a value of 4 is typically used where the accurate value is not known, k* is the average retention factor for which a value of 5 is typically optimal, ΔΦ is the change in organic composition from the scouting gradient, V m is the column volume (see equation 2) in milliliters, and F …
