CHEMetrics Inc., Midland, Va., has four new test kits employing the HBA method to measure ammonia in potable water, surface water, storm water, groundwater and wastewater. The kits offer a shorter analysis time and extended measurement range. Additionally, the mercury-free HBA reagents are said to benefit customers who wish to eliminate the use of mercury in their facilities.

The new ammonia test kits use a modified Berthelot method like the salicylate method; however salicylate is replaced by a different phenolic compound, hydroxybenzyl alcohol (HBA). This reagent reduces the color development wait time from 15 to five minutes.

Ammonia (HBA) test kits are available using CHEMetrics’ VACUettes Auto-Dilution Method. VACUettes kits employ a patented auto-dilution feature that eliminates the need for pipets and flasks. An extended range is also available for the company’s instrumental Vacu-vials test kit. Other advantages of these new kits include improved packaging of accessory solutions for easier use and reordering.
