| + | 40 | The last caveat is the one most often overlooked. Species that do not absorb at the detection wavelength — inorganic salts, many sugars, water — are invisible, and species that do not elute within the run remain on the column and are simply absent from the chromatogram. A clean trace is evidence about what was detected, not about what was present.{{r|usp1503}} | |
