Fiber optic sensors are always the method of choice when little space is available. For such applications ifm is now launching the new fiber optic sensors of the OCF series. These can be set up intuitively, have numerous smart functions thanks to IO-Link and offer six powerful operating modes which the fiber optic amplifier selects automatically as required.
These sensors work on the same principle as conventional optoelectronic sensors. Here, however, optics and evaluation electronics are spatially separated from each other, which offers an important advantage for many applications: The fiber optics can be positioned precisely under very confined conditions and detect even very small parts there. The remote fiber optic sensor is then located in a suitable place – for example, mounted on the machine or even in a control cabinet.
The new fiber optic sensors make such applications particularly easy. The slim housings are suitable for mounting on DIN rails. There, they can be simply snapped on with a flick of the wrist. The fiber optic cables are also connected without tools thanks to the so-called fiberlocking. Since the OCF complies with the high IP65 protection class, it can also be mounted in the field, for example directly on the machine. In order to make the subsequent commissioning simple and intuitive, ifm placed great emphasis on usability during the development. The fibre optic sensor has three buttons for operation. The plain text display of the integrated OLED display facilitates the 2-point teach-in. The find-me function, in which the connected fiber flashes, also simplifies localization.
The OCF handles six different operating modes, automatically selecting the correct mode as needed. The output signal can be sent to a higher-level controller via IO-Link as well as via a fast digital output. The IO-Link interface is also used to diagnose the fiber optic sensor. For example, the degree of contamination of the fiber can be monitored; this clean-me function enables predictive maintenance in the application. Together with the new fiber optic sensors, ifm also offers a comprehensive range of matching fiber optic cables in a wide variety of designs so that the right configuration can be selected for every application.
Technologies Safeguard the Circular Economy of Valuable Metals
While copper and precious metals are essential components in the electronics and semi-conductor industries, lithium has also developed into one of the most important raw materials for rechargeable batteries and therefore the entire consumer electronics sector. The path from ore to metal is still very complicated. In addition to ore production, the extraction of metals to obtain the highest purity is a complex process. Only extremely precise and accurate analysis makes it possible to detect very low and ultra-traces, particularly in metal recycling. Analytik Jena provides an important contribution to a sustainable circular economy with their innovative technologies.
In contrast to precious metals, metals do not exist in their pure form but are bound in minerals and ores – which are sometimes very widely distributed, or sometimes only found in a few areas and in very low concentrations in the ore. Nevertheless, their extraction and recovery are worthwhile, because dwindling resources and an increasing demand for these valuable metals go hand-in-hand. It is therefore absolutely essential to extract and reuse scrap metal within the scope of metal recycling. This sustainable circular economy will continue to become increasingly significant.
However, the production and recovery of metals is highly complex and requires extreme precision to meet the high application requirements such metals need to meet. The accurate quantification of the metal that actually needs analyzing is affected by the content of other base metals such as copper, cobalt, chromium, nickel, iron or zinc and trace elements (through additives or contaminants). Analytik Jena covers the entire analytical process from ore to metal with its methods – from AAS via ICP-OES right up to ICP-MS – and the corresponding instruments.
High-Performance Atomic Absorption with the contrAA and novAA 800 Series
In the initial process steps of the value chain, numerous raw materials must be analyzed to obtain detailed specifications about the starting material. This involves the quantification of the main contents and concentrations of elements, primarily by means of flame AAS (atomic absorption spectrometry). The highly efficient instrument series of Analytik Jena, contrAA and novAA 800, master these tasks easily and cost-effectively.
Detecting Ultra-Traces with PlasmaQuant 9100 and PlasmaQuant MS
In the further process, the requirements for analytics change. Trace and ultra-trace elements can significantly affect the quality of high-purity metals or alloys, which is why their detection and subsequent elimination require even greater accuracy and precision. This is where the high-resolution PlasmaQuant 9100 ICP-OES series and the highly sensitive PlasmaQuant 9100 ICP-MS series offer maximum performance, and thus reliability and efficiency.
The AAS, ICP-OES and ICP-MS technologies offered by Analytik Jena are extremely well designed for the special requirements that need to be met in the individual phases of the value chain:
Robustness & User Friendliness
Especially the exploration of possible mining sites and the mining itself often take place under harsh environmental conditions and in very remote locations – not infrequently at very high altitudes. Air pressure and oxygen content are very low in such environments and can strongly affect the measurements. Suitable laboratory equipment is also usually rare in such locations. The analysis instruments offered by Analytik Jena are designed for such circumstances: User-friendly, easy to set up and if necessary, easy to use by personnel without in-depth specialist training.
Standardization & Efficiency
The availability of consumer materials at the mining sites is often just as rare as oxygen saturation. Rare or special chemicals are often difficult to obtain. The instruments therefore should not pose unreasonable demands, but should still meet the necessary high requirements. The all-rounder in elemental analysis, the novAA 800, for example, can be operated with LPG gas, which is available even in the most remote places on earth.
Sensitivity & Precision
The analytical instruments must be highly sensitive, accurate and precise due to the low concentrations of metals in the ores and the adverse effect of other metal present in the sample. The solutions designed by Analytik Jena offer suitable analytical methods for the quantification of even very low metal content in ores, contaminants in pure metals and for monitoring treatment processes. With their high sensitivity and low detection limits, the PlasmaQuant 9100 series and the PlasmaQuant MS series cover the entire concentration range – with peak performance offered by the PlasmaQuant 9100 Elite and PlasmaQuant MS Elite.
Automation & Economic Efficiency
As the quantity of samples for such routine applications is constantly growing, analytical instruments must meet the increased sampling rate through automation and/or innovative analytical techniques. This not only ensures improved throughput rates, it also reduces the overall costs for analysis and opens up resources for the workforce. The high sample throughput, especially of the PlasmaQuant MS Q makes it possible.
You can read about the specifics of how Analytik Jena’s instruments can meet all these factors and contribute to sustainable metal extraction and recovery in our detailed eBook “From Ore to Metal”.
