Promptly invert Every single vial ten instances even though Keeping the vial through the cap only given that the vial will likely be scorching through the response induced when including the sample.
Our patent pending chloride extraction procedure consists of using sulfuric acid to make gaseous HCl (Hydrogen chloride), that's then captured by an HCl absorption tube and soda lime indicator.
Recognizing this problem in the sector, we created a number of COD test kits that include a chloride extraction phase that ensures the interferences from significant chloride information are removed and generate accurate test results.
