Hach Co. announced the availability of laboratory products for compliance with the U.S. Environmental Protection Agency’s (EPA) new chlorine analyzer regulation, Method 334.0. These products can be used with any online chlorine analyzer that must meet the requirements of Method 334.0.
“In November 2009, the U.S. EPA released Method 334.0, which outlines proof-of-performance and quality control requirements for online chlorine analyzers to be used for reporting residual chlorine in a drinking water system,” said Thom Voll, Hach director of laboratory systems. “While the method provides requirements, specifications and acceptance criteria, it does not provide detailed test procedures. In response, the drinking water application experts at Hach developed a toolkit to help with compliance.”
The toolkit includes:
• “Step-by-Step Methods”: Created by Hach’s Laboratory Applications team, this document directly refers to each requirement outlined in Method 334.0 and provides test procedures for each;
• Pocket Colorimeter II, mid-range chlorine: New range: 0.05 to 4.00 mg/L. This new Pocket Colorimeter II provides readings with 0.01 mg/L resolution across the entire EPA-regulated range; and
• Spec gel standards: A new mid-range standard kit allows for simple verification of the mid-range on the new Pocket Colorimeter II.
