EPA Approval
Lachat MICRO DIST system for cyanide distillation receives EPA approval for NPDES and NPDWR reporting
On Monday, March 12, 2007, the US Environmental Protection Agency (USEPA) amended the Code of Federal Regulations (40 CFR Part 136) to provide full approval for a new method: "Digestion and Distillation of Total Cyanide in Drinking and Wastewaters using MICRO DIST and Determination of Cyanide by Flow Injection Analysis," also referred to as QuikChem® Method number 10-204-00-1-X by Lachat Instruments. This rule modifies the testing procedures approved for analysis and sampling under the Clean Water Act and Safe Drinking Water Act and applies to all facilities that must conduct monitoring and provide reporting to comply with NPDES and NPDWR permits.
"We’re very excited to receive USEPA approval for our Cyanide methodology", said Greg Hirt, Director of Sales for Lachat Instruments.  "Our customers have always loved the simplicity, performance and safety of the MICRO DIST product, and the fact that it can now be used for both NPDES and NPDWR compliance reporting purposes is a significant benefit. When you couple MICRO DIST with Lachat’s QuickChem 8500 Flow Injection Analysis system, you have one of the most productive, accurate and easy-to-use methodologies for determination of Cyanide on the market today."
The MICRO DIST system quantitatively scales down the sample and reagent volumes such as those required by macro-distillation in USEPA methods.  MICRO DIST is a batch micro-distillation system which uses sample volumes of less than 10mL. The key benefit of the system is a disposable, or recyclable polypropylene tube assembly.  MICRO DIST from Lachat Instruments allows users to distill up to 21 samples simultaneously for cyanides, sulfide, and ammonia in 30 minutes; and phenolics and tritium in 90 minutes.  MICRO DIST eliminates the need for bulky, expensive, clumsy and time-consuming glassware-based distillation units while accommodating liquid and solid samples.
Compared to other techniques, Lachat’s Micro Dist saves time, money and reduces the complexity of the distillation process. With any method used for compliance reporting, customers should always consult with the local regulatory authority – Lachat can assist you with technical information and details needed for your regulatory authority.
