Endress+Hauser showcases their laser technology

sible for worldwide business development for the laser-based Optograph Process RA- MAN analyzer product line manufactured by Kaiser Optical systems Inc. After a welcome by Rob MacKenzie, Managing Director of Endress+Hauser, Mr Roelstraete gave us an historical overview of the Tunable diode laser absorption spectroscopy (TDLAS) technology which delivers fast and accurate gas analysis measurements. The products are used in natural gas production, transport, stor- age, distribution, gas processing, refining, petrochemical, and specialty and bulk gas production. The analyzers measure Mois- ture (H 2 O), Carbon Dioxide (CO 2 ), Hydrogen Sulfide (H 2 S), Ammonia (NH 3 ), Acetylene (C 2 H 2 ), Oxygen (O 2 ). The headquarter is located in Houston, Texas with production facilities in Rancho Cucamonga, California. For more information on the company and the offering please visit www.spectrasen- sors.com. Kaiser Optical Systems, Inc’s principal products include Raman sensors and in- strumentation and advanced holographic components for spectroscopy, telecom- munications, astronomy and ultra-fast sciences. Off-the-shelf and customized solutions for end-users and OEMs are available. The special qualities of the Optograph chromatograph are that no valves, columns, carrier gas or instrument air are required.

The Africa Automation Fair 2015 took place from 5 – 7 May 2015 at The Dome, Northgate, Gauteng. As a showcase for industrial control technologies, it is one of the biggest, most comprehensive shows of this type held in the southern hemisphere. On Tuesday 5 May, ‘ChemTech’ at- tended a Laser Technology breakfast at the Africa Automation Fair as guests of Endress+Hauser. Laser technology is seen as a “real solution for industrial online gas applications”. The company has recently strengthened its analytics business on a broad scale. SpectraSensors, a global leader in laser-based gas analysis with absorption spectroscopy, became part of the Endress+Hauser Group in 2012 and the following year, Kaiser Optical Systems, a pioneer in the field of RAMAN spectros- copy, was acquired. Both companies will continue to operate as independent competence centres, but, because advanced analysis technologies are fast, reliable and highly precise and require no expendable materials and no special environmental conditions, they are cost-effective and low maintenance, thus driving down operational expenses. SpectraSensors’ gas analysers are de- signed for process control and monitoring applications and the RAMAN instruments from Kaiser Optical systems are used in production as well as in the lab. To tell us all about the technologies were visitors to South Africa, Koen Roelstraete, Director of International Sales at Spectra- Sensors, and Dr Peter van Vuuren, respon-
