Process analysis solutions – more than just device hardware

Benefits of Raman technology • Precise analysis in aqueous solutions guarantees that product quality or critical process parameters are moni tored in real time • Excellent signal separation for accurate substance infor mation with reduced effort for chemometric “calibration” • Easy scalability of the created analytical methods from the R&D laboratory into production, based on integrated wavelength and intensity validation Benefits of TDLAS • Contactless, laser-based concentration determination by optical unit isolated from the process gas • With respect to gaseous hydrocarbons in processes, the patented “differential spectroscopy” offers highly selective analysis at trace level • Extraordinarily fast and stable response time within sec onds of rapid changes in the concentration in the gas

Endress+Hauser Optical Analysis develops and produces a comprehensive portfolio of analytical systems and Raman probes for laboratory and process applications. Over 2,000 installed Raman and 12,000 TDLAS* analytical systems are the basis for our over 25 years' application experience. These modern, laser-based technologies are characterized by out standing reliability and maintenance friendliness. Application • Raman is an in-line analysis technique with a very broad application spectrum, suitable for chemical compounds in typical concentrations of 0.1-100% • TDLAS technology for online concentration determina tion of specific molecules in gases, such as H 2 S, H 2 O, CO 2 , NH 3 and C 2 H 2 , in the low ppm range for trace analyses • QF** spectroscopy for determining O 2 in process gases in the ranges of 0-10 ppm v to 0-100%

Process analytics calls for a high level of expertise, which is often not available in-house. This gives rise to a demand for turnkey solutions. Endress+Hauser caters to this customer requirement and has established important resources such as expertise and production skills. Our range of products and services • On-site consultation: in an initial discussion, we will explain the measuring options available and identify the requirements for the project • Flexible hire and leasing options • Project-specific documentation, 2D/3D drawings Raman-based • Feasibility studies including surveying of samples in our application lab • Chemometric model development • Retractable assemblies for Raman probes and automated cleaning control • IQ/OQ service for cGMP applications TDLAS/QF-based • Individually designed sample preparation with customer specific material requirements for pipelines and protec tion from ambient conditions • System integration including complete inclusion of third party technologies such as PGCs

Your benefits • Matched components and user training enable opti mum commissioning and reliable analyses • Turnkey and tested complete measuring points with clear interfaces • Many years of application expertise and large database of proven models and methods • Smart Support with response times of 24h and rapid spare parts availability thanks to our European service network • Tailored training programs
