Founded in 2017, Max-IR Labs develops infrared solutions for industrial process control, medical diagnostics and biochemical analysis. Our R&D is conducted in close coordination with customers, focusing on their application needs, and backed by market analysis.

We are moving infrared technologies from the lab into the field, bridging the gap between laboratory research and real-world application solutions meeting the needs of industrial, biomedical and defense end-users. Max-IR Labs’ intellectual property is protected by a strategic patent portfolio.

The Technology

Max-IR’s patented technology unlocks the plethora of information that exists in the infrared spectra but is difficult to analyze.

Traditional techniques such as ultraviolet, electrochemical, colorimetric and direct infrared interacting with the analyte liquid suffer from fouling and interferences and are unstable over time. Our technology enables the use of infrared spectroscopy even in the case of thick and opaque liquids where other methods fail.

Based on ground-breaking research by its founder, Max-IR seeks to solve the issue of analyzing the composition of liquids without creating any reaction, with accuracy, in real-time. The non-reactive method of measurement, coupled with a self-calibration technology to avoid measurement drift, ensures a low-maintenance sensor suited for industrial, biomedical, research, and defense/security applications.

An infrared signal is passed down a special optical fiber in contact with the liquid analyte. The electromagnetic field associated with the IR signal penetrates a short distance into the liquid analyte where it is absorbed by target compounds. This generates small changes in the IR signal, which are detected by the sensor.

The Sensor

Max-IR develops infrared (IR) sensors for analysis of compounds  in liquids, from clear to thick and murky. Using cutting-edge patented  technology, our sensors enable accurate, real-time, continuous measurements, without change or drift over time.

Max-IR's pioneering industrial grade sensor is based on infrared light passing through an immersed optical fiber.
Implementation of ion-selective material enhances differentiation between various molecules, making it ideal for on-site operations.

Quantum Cascade Laser
the source of the infrared light. QCLs are semiconductor lasers that emit infrared in the mid- and long-wave bands. We develop technology based on compact, high-power QCLs. Tunable QCLs are implemented for accurate spectral analysis of compounds in the examined liquid.
Replaceable Cartridge
holds an infrared wave guide to lead the infrared radiation while in contact with the analyte, and an ion-selective material to concentrate compounds of interest.
Infrared light waveguide - special optical fiber which is transparent in the infrared spectral range. These are immersed in the analyzed liquid to allow transmission of the optical signal through highly infrared-absorbing liquids. The infrared radiation transits from the QCL to a detector through the fiber, and the infrared radiation at the interface between the fiber and the analyte liquid is able to detect the characteristic infrared absorption spectra of compounds in the analyte.
Ion-selective material - allows monitoring of compounds of interest in liquids with high specificity and sensitivity by selectively concentrating compounds in the material
Infrared Detector
an infrared sensor that can detect minute changes in the IR radiation that interacts with various compounds. With noise-cancellation algorithms it is able to extract information on the composition of the analyzed liquid. The sensor delivers real-time, continuous, accurate readings and due to self-calibration, does not suffer from drift or inaccuracies over time.

Water & Wastewater treatment

Wastewater treatment plants are turning to sensor-based automation to enable inline process control, enhance energy efficiency, and reduce operating costs while improving treatment performance.

The Max-IR sensor measures nitrate and ammonia levels to monitor treatment efficacy, provide an early warning of process drift, and trigger a timely response in case of process failure. In the critical process of aeration, the introduction of air into the treated water uses more than 50% of plant energy consumption. Our sensor allows real-time feedback on the aeration process, reducing energy consumption and lowering overall operational costs.

Our sensor does not require constant maintenance, as is the case with competing sensor technologies (UV and ion-selective electrode). This robust, reliable performance in challenging environments drives cost savings and better water quality.

Urine, blood and biological fluid analysis

The Max-IR sensor can provide significant advantages in biomedical applications. When analyzing biological fluids, including urine and blood, it can detect and quantify a range of different molecules, such as sugar molecules, each bearing different infrared spectral features. The ability to detect and quantify specific molecules in urine, blood and other fluids enables the identification of metabolite signatures associated with specific bacteria, aiding in disease diagnosis.

Max IR’s sensors may be used in analysis providing an accurate bacterial profile of biological samples, in real-time. The sensor does not drift overtime and remains accurate. It reduces the number of false positives helping prevent overtreatment.

The same abilities can measure markers in blood, in medical environments or in law enforcement scenarios (checking alcohol and other substance content in blood).

Food and
beverage process control

The Max-IR sensor works accurately in complex environments, such as food safety where there is a constant need for fast, efficient and accurate sensing. Applications include food safety, bacterial contamination, and measurements of antibiotic levels in food products to ensure quality control.

Indicators such as sugar levels, alcohol content, CO2 levels and other parameters can be measured inline, without any interference with flowing liquids. Clean-in-place (CIP) protocols can be improved, for better water and cleaning solution usage efficiency.

Analyzed fluids are not altered or interfered with, making Max-IR’s sensor a great candidate for process control in the food and beverage industry, where flowing liquids require continuous monitoring.

Energy industry

In oil and gas and petrochemical industries, real-time chemical analysis is required in a broad range of operations, from fuel-blending to monitoring of biodiesel properties. Infrared spectroscopy allows real-time analysis of hydrocarbon composition such as aromatics content, olefins, benzene, and ethanol, among others. Applications within this industry are diverse and include monitoring of volatile organic compounds (VOCs), such as benzene, toluene, ethylbenzene, and xylenes (BTEX) in groundwater; or monitoring of methanol in the transesterification process in biodiesel production.

Another example is monitoring of methanol in subsea methanol reuse and recovery operations, where methanol is used in deep, cold waters to inhibit the formation of hydrates that can block production flow.
