Increased scrutiny has been placed on drinking water safety, specifically for monitoring perchlorate and bromate levels. In order to minimize exposure of these toxic compounds for regulatory requirements, their detection in drinking water has become a key focus. Bromate, classified as a potential carcinogen, is generated from the ozonation of bromide-containing minerals in drinking water. Perchlorate is a ground water contaminant which interferes with iodide uptake by the thyroid. It can be found in natural-occurring minerals and as a contaminant from the pyrotechnic industry. The increased mass sensitivity of capillary IC permits monitoring of these disinfection byproducts at lower detection limits.

This webinar will demonstrate the advantages and applications of 2D-IC where the sample is initially separated on a 2 mm or 4 mm column set. The peaks are then separated from the sample matrix on a capillary IC column. Both analytes are determined directly with suppressed conductivity detection. The webinar will be of value for anyone interested in specific methods that combine both the advantages of standard IC and capillary IC.

Subject Areas Covered in Presentation:

• Learn about the benefits of capillary IC for trace contaminants

• Learn about using 2D-IC to eliminate matrix effects and increase sensitivity

• Learn about applications for the environmental and food/beverage industry
