Conclusions and Future Trends
The application of mass spectrometry techniques has paid special attention to
the analytical skills related to the achievement of good sensitivity for control,
quantification of these contaminants as well as their identification includ-
ing the main degradation products. Pre-concentration of antifouling booster
biocide residues is a decisive step for the determination of trace levels. The ex-
traction efficiency of LLE, SPE and current techniques involving SPME, SME,
MAE or SFE makes these a feasible approach for booster biocide analysis. LC-
MS methods have experienced progress in terms of application in the analysis
of booster biocides, and are especially suitable for environmental sample an-
alysis for routine confirmation of identity as well as structural elucidation or
ultra trace analysis. However, up to now, the development of methods with
current instrumentation such as MS
MS for antifouling compounds, which
are amenable to separation by GC or LC, has not profusely applied. However,
we can expect an increase in the use of these LC-MS tandem techniques as
well as LC-TOF-MS as methods to improve identification and quantification
performance.
