GC/electron capture detection (ECD) is also used to measure DBFs. In particular, EFA Method 552.2 and 552.3 are commonly used to measure haloacetic acids in drinking water [156, 157]. ECD is very sensitive toward halogenated compounds and allows low-level detection for HAAs (0.012-0.17 pg/L detection limits for EFA Method 552.3).

An MIP film attached to a quartz resonator of the QCM transducer has been used successfully to devise a chemosensor for determination of disinfection by-products of haloacetic acids in drinking water [128]. An ACN solution of trichloroacetic acid (TCAA), VPD, EGDMA and AIBN, used as the template, functional monomer, cross-linker and initiator, respectively, has been polymerized thermo-radically. Next, the resulting MIP was spin-coated on a quartz resonator to form a thin film. The TCAA template was then extracted by rinsing the film with water. This TCAA... 

As a result of the disinfection of drinking water by means of ozone, chlorine dioxide, chloramine, and chlorine, a variety of disinfection byproducts may occur in drinking water, including oxyhalides, haloacetic acids, and halogenated AEO and APEO metabolites (Ch. 8.4.2). The LC-MS analysis of disinfection byproducts in drinking water was recently reviewed by Zwiener and Richardson [65].

In the disinfection process of drinking water, besides other chlorinated compounds, halogenated carboxylic acids arise. For quality control of drinking water the determination of these contaminants was established using LC-MS with a preference for ESI (cf 15.3.3.2 ESI, haloacetic acids). An application of APCI-MS for haloacetic acid analysis was reported after CE separation in a non-aqueous medium [303]. 

Perhaps the most spectacular of the early results that demonstrated the potential of FAIMS as a mobility filter for MS was in the detection of nine chlorinated and brominated haloacetic acids at the part-per-triUion levels in drinking water. - The selectivity and efficiency of ion transmission through the FAIMS into the MS improved the detection limits of these compounds by three to four orders of magnitude over conventional ESI-MS methods.

The advantages of IC-MS such as sensitivity and selectivity are noticeable in the analysis of drinking water (e.g., for the determination of perchlorate, the analysis of haloacetic acids or of disinfection by-products). Other fields of >pli-cation are clinical and biochemical research (determination of organic acids, amines, or sugars),pharmaceutical industry (peak identification and purity tests), petrochemical industry (determination of indicator substances), food industry, electroplating industry, analysis of hazardous substances, and environmental analysis.
