Determination of measurement uncertainty of spark OES made easy!

Join this new webinar, Determination of measurement uncertainty of spark OES made easy!

About this webinar: 

Every year an increasing number of laboratories using OES (Optical Emission Spectroscopy) spectrometers get accredited according to DIN EN ISO 17025.

Compliance with DIN EN ISO 17025 has elevated the importance of estimating and reporting measurement uncertainty. DIN EN ISO 17025 says that for each measurement result the measurement uncertainty must be calculated.

The Guide to the expression of uncertainty in measurement (GUM) provides guidelines for conducting an uncertainty analysis.

Unfortunately, implementing these guidelines can be a daunting task, especially if one is not familiar with the necessary mathematical and statistical concepts.

Consequently, testing and calibration personnel must often find off-the-shelf tools that meet their analysis requirements.

This webinar presents such an off-the-shelf tool, as well as the way that Thermo Fisher has implemented in its analytical software the calculation of the measurement uncertainty. It also describes an application based on the knowledge of the uncertainty in the goal to calculate the product conformance probability.

Watch a short clip from the webinar below:

Determination of Uncertainty

Key Learning Objectives:

  • Why it is important to determine the measurement uncertainty
  • Which norms and standards are applicable
  • Two approaches on how to determine the measurement uncertainty in a simple way

About the webinar speakers:

In 1989, Wilhelm started his professional career at SPECTRO Analytical Instruments after studying Physical engineering at the Rheinische Akademie in Cologne, where he gained his first experience with optical emission spectrometers, which also ignited his passion for this technology. Since then, Wilhelm has worked in this field for various companies and roles. First in applications, then in automation and later in service and sales. Since 2011, he worked for Oxford Instruments, whose industrial analysis division was acquired by Hitachi-High-Tech in 2017. There he was working as product manager responsible for the complete OES product portfolio which included bench top and mobile spectrometer types only. Since 2021, Wilhelm is working in this role for Thermo Fisher Scientific, as the task of developing high-resolution "high-end" spark spectrometers really appealed to him. What he likes on this role is that it enables close contact with our customers and interaction with research and development.

Dipl. Ing. Thomas Asam ventured into self-employment in 1995 and founded TAZ GmbH. In a backyard of an Andechs farm, a modern glow discharge spectrometer was built from new electronics, newly developed software and a large number of other individual parts.

In 2003, Ulrike finished to study geology at the Technical University of Munich. As life not always follows a straight line, she got the possibility to work on a research project on lead-free solder alloys as a scientific assistant and head of laboratory at the Applied University of Augsburg. During this time her major task was investigation of solder alloys and intermetallic phases in solder joints with SEM/EDX/EBSD.

In cooperation with the Freie University of Berlin, Ulrike received her PhD in 2017 for her work in this research project.

In 2015 she started at the TAZ GmbH as an application engineer for damage analysis. In the recent years the focus of work changed more and more to quality management topics. So now she is in charge of the whole quality management and accreditation in accordance with the ISO/IEC 17025 standard of the testing laboratory TAZ GmbH. At last, for about 4 years now Ulrike is also quality manager for calibration laboratory for optical emission spectrometers TAZ Servicetechnik GmbH & Co. KG, which is also accredited in accordance with the ISO/IEC 17025 standard.
