FRED-Arsenic™

A FRED-Bio Sensor

The Field-Ready Electrochemical Detector® system for arsenic.

What's in your water?

Understanding chemical concentration in real-time is difficult. Sites must be driven to, analytical labs introduce delays, and field kits are difficult to use or lack data integrity. FRED is designed to be robust, fast, and easy to use in a variety of process waters. FRED can decrease operational cost, remove rework from travelling to the site more often than required, and provide needed information to process engineers without the hassle of expensive custom installation.

Arsenic is a naturally occurring and industrially produced chemical which is highly toxic. Being known to cause many health problems, such as vascular diseases and cancers, it is essential that arsenic levels be managed in drinking water applications.

Portable, total analysis for arsenic.

Producing rapid arsenic data when and where you need it. FRED-Arsenic is designed to take virtually no sampling time, while providing lab comparable data for drinking, environmental, and process water. FRED is one of the first ever portable arsenic speciation (As3+) and total arsenic (As3+/As5+) analysis tools, quantifiable to less than 0.01 mg/L (the EPA standard drinking limit for arsenic). FRED-Arsenic is designed with operational efficiency in mind. Use our sensor system to optimize your treatment protocols and take control of your monitoring process.

Make faster decisions

FRED reduces waiting time and lets you get the data you need while in the field.

Designed for operators

FRED is designed to integrate with your infrastructure, from hardware to software.

Accurate and precise

FRED is custom-designed to reliably quantify arsenic in your water system.

Field-ready

FRED lets you make decisions in the field by sampling and analyzing water quality at site.

FRED-Arsenic is a different way to think about water testing.

The system is designed for ground and surface water arsenic measurement using a novel, biological-based method of detection. Non-hazardous bacteria are stored in a sealed cartridge and are activated when a water sample is added. Collect your GPS, time stamped data on-site without having to wait for lab analysis. Make your decisions right away.

How it Works

Step 1

Fill cartridge—no sample prep required

Step 2

Place cartridge in detector—bacteria will sense chemical

Step 3

Wait for the results to be transmitted

Step 4

View your data immediately on your computer

Validation and Testing

FRED has been trialed with several USA-based utilities. The primary use case involved the validation of the instrument with groundwater wells actively above the maximum contaminant limit of 10 µg/L arsenic. Our data is compared to standard EPA approved compliance methods (e.g., ICP-MS analysis) to demonstrate specificity and accuracy.
