40 Process Measurement

40 Process Measurement Technology Single Particle Explorer (SPE) © rap.ID Particle Systems GmbH Butterfly Ridge Waveguide Laser © eagleyard Photonics GmbH Laser Sources in Process Measurement Technology With ridge waveguide lasers (RWL) from eagleyard photonics and with the aid of diffractive optical elements, it is possible to generate a variety of beam patterns – which are necessary in order to precisely measure 3D surfaces with CCD sensors. Due to their excellent beam characteristics, lasers are the ideal source for large-area measurements as used in the automotive industry, as well as for contactless measurement of speeds from a distance in a variety of industrial applications. www.eagleyard.com 2 Foreign Particle Analysis In carrying out foreign particular analysis, rap.ID applies particle image analysis systems with automated Raman identification in combination with other methods, such as EDX, IR spectroscopy and laser induced breakdown spectroscopy (LIBS – metal.ID). These innovative systems and services are used throughout the world to detect contamination in production processes. rap.ID can provide information on the number, size and chemical composition of the particles.By working closely with customers, it’s possi- ble to carry out foreign particle tests on products in order to develop specific methods for routine foreign particle testing and characterization. If required, the methods can be validated in accordance with the demanding standards of the pharmaceutical industry. www.rap-id.com | www.metal-id.com Measuring Optical Assemblies Developing new optical assemblies requires the highest levels of precision. Berliner Glas has been developing expertise in this area for decades. It not only manufactures assemblies, but also characterizes them. It writes its own software to analyze measurement data for customized specifications. Selected measurement technologies include: • Wavefront measurements • Measurements of size, shape and position • Angle measurements of optical components • Micro-roughness • Spectral reflection and transmission measurement • (Cylinder lens) centering • Imaging performance • Metrology developments www.berlinerglas.com 3 2 www.eagleyard.com/markets/industryinstruments/metrology 3 www.berlinerglas.com/engineering-expertise

Environmental Analysis 41 5.2 Environmental Analysis Introduction How clean is our water? And what will the ozone levels be this summer? What sorts of contamination must be taken into account before a former industrial site can be developed? To answer questions like these, environmental analysis must first undertake a qualitative and quantitative examination of substances in the environment. Berlin and Brandenburg have developed tightly networked structures for this purpose, bringing together large, medium and small research institutes into close collaboration with a variety of mainly medium-sized companies. An extract of these structures is found in the following. pulse is emitted and the time it is reflected back. Measuring the oxygen-dependent interval makes the method resistant to interference of any kind. Years of practice have shown that this method overcomes the disadvantages of traditional electrochemical measurement techniques. The minimal maintenance required by the sensor make it inexpensive to operate. The long-term stability of measured values increase process reliability and help produce savings, for instance, in terms of the aeration energy required in municipal and industrial wastewater treatment plants. www.hach-lange.de Trace Analysis BAM Department 1 comprises several divisions that deal with the various aspects of environmental analysis. These include, for example, inorganic and organic trace analysis, environmental analysis as well as a division for chemical and optical sensor technology. Special fields of competence include inorganic trace elements, element speciation and isotopic analysis, especially of pure substances, environmental, biological and medical materials, along with the development of suitable analysis procedures and instruments. While in part focusing on analyzing pollutants in soil, air and water, the department also develops analytical methods to determine the presence of ethyl glucuronide (ETG) in hair, for example, which serves as a biomarker for the classification of alcohol consumption. Environmental analysis is also concerned with antibodies and their analytical use – which is another area that BAM is working on, in collaboration with a variety of companies and research institutes. Oxygen Measurements In absorption spectroscopy, lasers provide for non-contact and remote measurement of oxygen. eagleyard photonics provides DFB laser diodes (DFB-760, DFB-764) that achieve the greatest oxygen absorption lines. Due to their significantly higher output power compared with other lasers (e.g. VCSEL), they are ideally suited for industrial applications under difficult measuring conditions. Excellent long-term wavelength stability makes regular recalibration cycles obsolete, which can significantly reduce the customer’s operating expenses.

Using a luminescence measuring process, for instance, it’s possible to measure the period between the time a light X-ray Analysis X-ray fluorescence analysis (XRF) is an established method for measuring the concentration of individual elements in biological samples. Bruker Nano offers a variety of XRF devices that make it possible to examine the metabolism 1 www.bam.de/en/kompetenzen/fachabteilungen/abteilung_1/index.htm 2 www.eagleyard.com/markets/industryinstruments/analytics
