QuickCODlab for COD Reagent-Free Chemical Oxygen Demand Analysis

Traditional COD testing requires hazardous reagents, lengthy digestion cycles, and extensive laboratory preparation. These methods increase operating costs, generate chemical waste, and delay critical wastewater decisions.

The LAR™ QuickCODlab™ is a laboratory Chemical Oxygen Demand (COD) analyzer that uses patented 1,200°C thermal oxidation to directly determine COD without potassium dichromate, sulfuric acid, mercury, or other hazardous reagents. Results are available in approximately three minutes, allowing laboratories to improve productivity while delivering accurate and repeatable wastewater measurements.

Why Choose QuickCODlab?

How the QuickCODlab Works

Step 1 – Inject the Sample

A small water sample is introduced into the analyzer.

Step 2 – High-Temperature Oxidation

Organic compounds are completely oxidized at approximately 1,200°C.

Step 3 – Direct COD Measurement

The resulting gases are measured to determine Chemical Oxygen Demand accurately and rapidly.

Unlike conventional COD testing, no hazardous digestion chemicals are required.

Frequently Asked Questions

What is Chemical Oxygen Demand (COD)?

Chemical Oxygen Demand (COD) measures the amount of oxygen required to chemically oxidize contaminants in water. It is widely used to evaluate industrial wastewater quality and treatment efficiency.

What makes the QuickCODlab different?

Unlike traditional laboratory COD analyzers, the QuickCODlab™ uses 1,200°C thermal oxidation instead of hazardous chemical digestion. This eliminates reagents, reduces analysis time, and minimizes hazardous waste.

How long does a COD test take?

Traditional COD testing often requires around two hours of digestion. The QuickCODlab™ provides results in approximately three minutes, significantly increasing laboratory throughput.

Does the QuickCODlab hazardous chemicals?

No. The analyzer performs reagent-free COD analysis and does not require potassium dichromate, sulfuric acid, or mercury salts during routine operation.
