The limits of detection (LOD) of analytical methods can vary depending on several factors such as the instrument used, sample matrix, and specific analyte being measured. However, here are some general estimates of the LOD for the following analytical methods used with capillary separations:
a) Fluorescence: The LOD for fluorescence detection can be highly sensitive, typically in the range of picomoles (10^-12 mol) to femtomoles (10^-15 mol) for highly fluorescent compounds.
b) Mass Spectrometry: Mass spectrometry can provide very low LODs, often in the range of attomoles (10^-18 mol) to zeptomoles (10^-21 mol) for many analytes.
c) UV-Vis Absorbance: The LOD for UV-Vis absorbance can vary depending on the specific compound and the instrument used. However, it is typically in the range of nanomoles (10^-9 mol) to micromoles (10^-6 mol) for most compounds.
d) NMR: NMR is generally not as sensitive as fluorescence or mass spectrometry. The LOD for NMR can range from micromoles (10^-6 mol) to millimoles (10^-3 mol) for most compounds.
It is important to note that these estimates are general ranges and can vary depending on the specific conditions and parameters used in each analytical method.
a) Fluorescence: The LOD for fluorescence detection can be highly sensitive, typically in the range of picomoles (10^-12 mol) to femtomoles (10^-15 mol) for highly fluorescent compounds.
b) Mass Spectrometry: Mass spectrometry can provide very low LODs, often in the range of attomoles (10^-18 mol) to zeptomoles (10^-21 mol) for many analytes.
