Mantech - Oxygen Demand Analyzer

Drinking Water, Fully Characterized

MANTECH’s revolutionary peCOD Analyzer technology measures the chemical reactivity and associated oxidative changes in Natural Organic Matter (NOM). As a result it is more sensitive than Total Organic Carbon (TOC) and UV254 to changing NOM concentrations in source and treated drinking waters.

Models and Specifications

The L50 is a direct replacement for the L100 shown in previous videos and pictures.  The L50 offers a simpler, industrial and robust design, with improved pricing over the L100. 

The peCOD Analyzer is available in laboratory, portable and online configurations that are highly customizable. The peCOD system can be configured to accommodate laboratory operations, automated sampling, or continuous process monitoring.

Available models

The Benchtop L50 peCOD Analyzer is MANTECH’s base model for use in municipal, government and academic lab settings.


System Benefits:

Small footprint (280 x 210 mm, 11.00 x 8.25 in)

Lightweight (7 kg, 15.5 lb)

MANTECH’s PeCOD Pro™ software adds automation and a sleek user interface

Can be upgraded to Automated or Online systems

The world’s fastest method for oxygen demand (OD) analysis is also available in a portable field unit. Just add the battery and carrying case and OD can be measured in the field!


System Benefits:

Small footprint (508 x 355.6 x 609.6 mm, 20 x 14 x 24 in)

Convenient case with wheels (weighs approximately 16 kg, 35 lb with analyzer & supplies)

No sample digestion is required, making it a truly portable technique

MANTECH’s PeCOD Pro™ software adds automation and a sleek user interface

System Benefits:

Unattended, continuous analysis of 73 samples

System is pre-calibrated before the start of each work day

Additional parameters can be added on, including pH, EC, alkalinity, BOD and turbidity

The Online L100 peCOD Analyzer will automatically grab samples from a low flow line or water tank, at scheduled time intervals.


 System Benefits:

Save time and money through process optimization with real time OD results

Option to add automated pH adjustment and dilutions

Additional parameters can be added on, including pH, conductivity, alkalinity, and ammonia


peCOD is the fastest available method for quantifying oxygen demand (OD), providing operators with real time data needed to make timely, impactful decisions that enhance environmental protection while generating substantial savings on chemical and energy use. It offers a low detection limit (< 1 mg/L) with results generated in less than 10 minutes.

peCOD offers a safe, fast and green chemistry method that can be used by anyone. This eliminates the need for trained analytical chemists on staff or an external lab facility

The core of the technology is the peCOD sensor, which consists of a UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst coupled to an external circuit. When a sample is introduced into the microcell containing the peCOD sensor, the TiO2 is irradiated by UV light, and a potential bias is applied. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized. peCOD is extremely accurate across a broad range of organics. The powerful oxidizing potential of UV-illuminated TiO2 ensures that virtually all species will be fully oxidized giving a true measure of OD.

The peCOD Analyzer is available in a variety of configurations that use the same innovative technology and method. peCOD combines robust performance and flexibility to suit the needs of your laboratory or process operations.
