The new SAMs provide unprecedented economy, simplicity, and accuracy for dedicated photometers. The instrument uses an LED as a light source and features a long-lasting silicon photodetector. To perform a test, the user snaps off the tip of a Vacu-vials ampoule below the surface of the sample. When the tip is broken, the sample is automatically drawn into the ampoule, where it reacts with DDPD reagent to form a blue-violet color. Total analysis time is approximately 2 minutes.
Ozone is more effective than chlorine at inactivating the parasites cryptosporidium and giardia.
In the water treatment community, many prefer ozone because it does not produce harmful by-products. Because of these unique qualities, ozone is widely used to purify water. Ozone treatment levels must be monitored closely to ensure the effective cleansing of the water system. This practice serves to disinfect the outer skin, which prolongs shelf-life. Both of these applications demand simple, accurate, and fast on-site testing of chlorine.
