This paper presents a systematic study of pure inorganic binary salts using
a time-of-flight (TOF) static secondary ion mass spectroscopy (S-SIMS) ins
trument. The objective was to evaluate the method's capability to achieve m
olecular speciation of binary salts. The results show the feasibility of di
rect speciation in a deductive manner without the need for reference spectr
a. Also ratioing intensities of specific high-mit cluster ions can differen
tiate compounds with the same elements in different oxidation states. (C) 2
