Minimise operator bias, calibration errors and interference errors in your measurements.

Achieve real-time cyanide control with standardised data available 24/7 for analysis through our online control platform.

Stabilise and reduce your cyanide consumption with faster and more accurate results without the risk of interferences.


Save productive time and resources needed for collecting, preparing and filtering samples, and repeating failed manual cyanide measurements.

Complete measurement within 60 seconds, anywhere on site, and perform up to 10x more measurements than before using traditional methods.

Adhere to health and safety standards without having to handle litres of cyanide-containing samples anymore.

Achieve peace of mind with our hazard-free solution that requires a maximum of 1 mL from your cyanide sample.

Examples of use cases by objective

Replacing manual titrations

Unreliable, manual cyanide titrations are the root cause in most mines. In addition to their highly variable measurement performance and lack of standardisation, silver nitrate titrations often over- or underestimate the exact cyanide content due to naturally interfering metals, leading to excessive cyanide consumption and diminished gold recovery.

By replacing the manual method with the fully standardised, digital CyanoGuard solution, mines achieve more consistent, real-time measurements and are able to reduce cyanide consumption and improve gold recoveries.

Complementing automated analysers

Automated analysers alone are often not enough to fulfill the cyanide monitoring needs of gold mines due to regular downtime and the need for frequent calibration.

Complementing their cyanide control strategy with a reliable, handheld cyanide monitoring solution gives them the flexibility to perform measurements anywhere and the security of a fully redundant, calibration and downtime-free technology. Mines have also successfully used our solutions to verify the accuracy and errors of automated analysers to avoid the risk of systematic errors.

Obtaining results faster in remote sample points

Sites with remote laboratories or long distances between the point of sampling and the point of measurement must wait several hours or days for results. Without access to real-time cyanide concentration data, it is impossible to achieve an efficient cyanidation process. Also, studies have shown that if cyanide samples are not measured quickly, results are biased.

With our solution, operators can measure virtually any liquid cyanide sample on the spot and obtain reliable, standardised results in seconds. All data points are instantly available online and remotely accessible from anywhere for real-time process optimisation.
