Chlorine 9056A
$95.00
Description
Most test methods for reading chlorine are actually reading Total Halogens, but the results can usually be considered the same because chlorine is by far the most common of the elements in the Halogen family on the periodic table. Other halogens include fluorine, bromine, iodine, astatine, and tennessine.
This test (EPA Method 9056A) actually reports chlorine and is the most accurate test, with a minimum detection limit of 50 ppm. We do not do this one in-house, so results take an extra week.
Minimum amount of oil required: 90 ml (one full sample bottle)
