Meet the future of process and quality control

Achieve the next level of efficiency and product consistency in mining, coating, and recycling processes with S2 KODIAK!

Real-time process monitoring is one of the most important measures to ensure products are manufactured cost-efficiently and to the desired quality.

At the same time, it is challenging to implement an analytical instrument into the process. This is where the S2 KODIAK shines! It works autonomously and maintenance-free 24/7, delivers immediate results, and the integration into plant control is flawless.

Applications include online and inline analysis of element concentrations and layer thicknesses in the natural resources industry, building materials manufacturing, scrap metal recycling, coating processes, with Positive Material identification (PMI), and high volume bulk food processing.

In addition, working safety is an important topic; conventional inline systems are based on prompt gamma neutron activation analyzers (PGNAA) and require extensive radiation shielding and strict safety and security regulations. Not with the S2 KODIAK. X-rays are emitted only in operation; simple shielding and the safety circuit ensure the highest safety level, at any time.

S2 KODIAK - Strong as a Bear!

  • Online and Inline Analysis in Real-Time for Tough Conditions
  • The Go-To Solution for Elemental Analysis and Layer Thickness Measurements 24/7
  • Remote-controlled, encapsulated, no radioactive source – safe, reliable, S2 KODIAK!  



High-quality Results for Elemental Composition and Layer Thickness

Instantly, at any time, with the performance you need – thanks to S2 KODIAK.

The S2 KODIAK inline XRF analyzer delivers reliable, 'real-time' results for both elemental composition and thickness and is capable of running in a production environment 24/7.
It measures processed material non-destructively – without sample preparation – making the S2 KODIAK the ideal instrument for online process control.

Maintenance-free and with few installation requirements, the S2 KODIAK is easily integrated into industrial processes.

Work Safety and Operator Ergonomics

The S2 KODIAK does not use radioactive targets and hence makes extensive radiation shielding obsolete. This not only makes daily work routines easier, but also simplifies integration in existing plants and facilitates approval processes with authorities.

The S2 KODIAK is remote-controlled, no operator on the device required.

Analysis Performance, 24/7

The S2 KODIAK analyses element concentration, layer thickness, and area density of single- and multi-layer coatings on metallic, non-metallic, and polymeric substrates simultaneously, online, and in real-time.

The S2 KODIAK transfers the results to the plant control software so that you stay in control of your process all the time.

Due to its encapsulated, rugged design with stainless steel casing (enclosure protection class up to IP69k), operating temperatures from -25 up to 60° C, an integrated UPS, empty belt detection, automatic self-alignment, pass/fail function and sample distance compensation, the S2 KODIAK ensures autonomous operation 24/7 with uptimes of 98% or higher.


Base Metal Mining

The S2 KODIAK is perfectly suited for online process control in mining operations. By measuring the exact material composition at any time, the hydro- and pyro-metallurgical processes can be optimized to increase output and enhance concentration efficiency. Real-time control of the blending step ensures a constant concentrate composition in support of later refining steps.

The S2 KODIAK works with base metal ores, such as iron, nickel, copper, chromium, molybdenum, titanium, tungsten and delivers immediate results for all of them.

The same time the S2 KODIAK analyzes major and minor elements, it also delivers information about hazardous trace elements, such as As or Hg. Lower-quality material can simply be diluted down or excluded from further processing.

Inline Coating Measurement

One of the most challenging processes in industry is the coating of advanced materials: Thin layer systems are used to protect valuable material, making it resistant to environmental impacts whereas multilayer systems are crucial to the functionality of solar cells and some electronic components.

In all of these production processes, the coating speed, precision of layer thickness, and composition of the layer are critical to cost efficiency and yield.

The S2 KODIAK is a valuable tool for in-line quality assurance of coating production processes - obtaining fast, precise and accurate results for layer thicknesses and compositional homogeneity.


Metal Recycling

For a modern, sustainable society, recycling of used material and goods is inevitable. Various metals and alloys are used in an endless list of products, such as steel, aluminum and copper in automotive. The recycling rate of various types of scrap metal is continuously improving and so are the requirements for the scrap quality.

For examples, the concentrations of elements such Cu, Cr, Mo, and Ni in recycled iron-based metal should be kept below certain limits to allow the use for steel production.

The S2 KODIAK is an important tool to optimize the metal sorting processes and verify the quality of the recycled material – all live and in-line!
