Notes:
The detection limits of a series of small peptides derivatized with 4-aminonaphthalenesulphonic acid have been determined using a magnetic sector mass spectrometer operated in the negative-ion mode. The instrument (AutoSpec-QFPD) is equipped with an electrospray ion source and both array and point detectors. Detection limits when using the array detector were on the sub-femtomole level at a mass resolution of 2000 (full width half maximum height). Cone-voltage and linked-scan collision-induced dissociation spectra were recorded using both the array and point detectors. When using the array detector, amino acid sequence information could be obtained from as little as 50 fmol of sample consumed.
