The review will discuss procedures, varying from the simple wet techniques to the
sophisticated and expensive instrumental procedures, from bulk analysis to specie-specific
techniques. Establishing mass balance using analytical techniques with batch samples of
corrosion inhibitors as standards can be tricky. Factors such as partitioning, chemical
reactions with other chemical species, adsorption onto solids, solubility changes, etc. must be
understood and considered in the calculations. The utility and applicability of the methods will
be compared with respect to cost and ease of setup, range of applications, selectivity, accuracy,
detection limit, reproducibility and limitations. The review will include analysis of the industry
needs and challenges facing the researchers developing new procedures.
