Hach announces three new TNTplus reagent sets: Copper, High-Range (HR) Nitrite and Mercury-Free Chemical Oxygen Demand (COD). Ideal for wastewater (copper, HR nitrite and COD), drinking water (copper) and industrial applications (monitor/control copper-based alloys, HR nitrite as an oxygen scavenger in closed-cooling systems), these new products help make laboratory testing with spectrophotometers easier and more accurate, the company said.
TNTplus products work exclusively with the Hach DR 2800 Portable and DR 5000 UV-Vis spectrophotometers to increase productivity and minimize analytical errors. Barcode scanning enables automatic method and wavelength selection. The instrument rotates the TNTplus vial, takes 10 measurements, and displays the average — any outlying measurements are rejected. No blank is required for most parameters and reagents are located inside a sealed cap, the company said.
