COD化學需氧量水質檢測 - Hach全球水質分析技術方案

COD化學需氧量水質檢測

無論是何種產業應用, Hach提供您完整的Chemical Oxygen Demand (COD) 檢測分析

Total confidence in COD analysis

Look to Hach for your complete COD testing solution. Our samplers, instruments, chemistries and lab supplies work together to provide superior results.

COD provides a measure of organic removal by treatment processes. Use COD as a surrogate for BOD and for effluent reporting when regulations allow.

	Sampling Water quality data relies on sample integrity. Correct sampling procedures deliver accurate lab results, a critical component for reporting and process monitoring.
	Sample Preparation Hach offers a continually expanding selection of laboratory supplies to cover a range of analytical testing needs. COD must-haves include industrial-strength blenders and test tube racks.
	Digestion Reactors Easy to use and fast, safe to operate and versatile, Hach DRB reactors accommodate most test vials. Choose a dual block for running two programs at the same time. Reagents Hach's USEPA-approved dichromate COD Method is the most widely used chemical oxygen demand method in the world for NPDES reporting and for easy process monitoring.
		Measurement: Lab & Process Genuine Hach instruments, chemistries, methods and expertise from one source give you incomparable results. Each of Hach’s easy-to-use spectrophotometers and colorimeters give you pre-programmed methods, factory calibration and automatic wavelength selection.
Hach開發之COD微回流測試法，操作過程簡單、快速、經濟，檢測結果與傳統滴定法具有良好比對性，並且可將COD（化學需氧量）測試過程產生的二次污染大幅降低。使用者無需自配COD試劑，方案包括Hach分光光度計/比色計，DRB200加熱爐以及搭配之COD預製試劑等。主要特點：  無需配製COD試劑：COD(化學需氧量)分析所需的化學組份依照一定比例製備而成的預製試劑管可大幅節省COD試劑配製所需時間  節省時間：整個分析過程，包括水樣消解、比色測定等步驟之所需時間小於3小時  消解裝置：DRB200替代傳統COD電爐回流裝置，可同時消解多達30個水樣  對環境產生的二次污染小：微回流法只需少量COD試劑，精心設計的COD試劑管可防止有機物的揮發以及樣品的逸出，確保消解過程之安全性  操作簡單易學：圖文並茂的操作指南讓使用者在短時間內掌握COD(化學需氧量)分析方法
