Accurate calibration and consistent instrument performance are essential for reliable results in elemental analysis. This live webinar explores the critical differences between type standard samples and control samples, and how each contributes to the accuracy, precision and stability of analytical workflows. Attendees will gain insight into when and how to apply these standards effectively, particularly in the context of metal analysis using arc/spark optical emission spectrometry (OES) and X-ray fluorescence spectrometry (XRF).The session will demonstrate how type standards are used to optimize calibrations for the analysis of specific alloy compositions, while control samples serve as ongoing performance checks to ensure measurement consistency. Using the Spark Analyzer Pro software as an example, this webinar will demonstrate how the relevant standards are integrated and applied within the device software, including correction methods and limit value settings, to maintain high-quality results across production and quality control processes.<h4>Why attend this webinar?</h4><ul><li>Learn how to apply type and control standards to improve measurement accuracy</li><li>Discover best practices for monitoring instrument stability in metal analysis</li><li>See how software integration supports reproducible elemental analysis workflows</li></ul><h4>Who Should Attend:</h4><ul><li>Quality control and process optimization professionals</li><li>Laboratory and production managers in metals industries</li><li>Anyone interested in advanced analytical technologies</li></ul>The webinar will take place on Tuesday, December 16, and will take around 30 minutes, after which we'll answer your questions live.<blockquote>Presenter: Dirk Scholten, Application Specialist Arc/Spark Analyzers</blockquote>

Difference Between Type and Standards in Elemental Analysis

Quality driven organizations recognize that preventing material mix-ups begins with reliable verification. Modern manufacturing environments depend on processes that can distinguish unknown alloys from known specifications with confidence – relying solely on labeling is insufficient. Consequently, Positive Material Identification (PMI) is essential for preventing mix-ups and safeguarding product quality.In this live webinar, you’ll learn exactly when to use Grade Identification / Grade Search for unknown materials, and when to rely on Grade Control / Grade Verification to confirm an expected grade quickly and confidently.If you know what the grade should be, verification gives you the fastest, clearest answer: OK or No Match. If you don’t, identification helps you narrow down possible candidates from your grade libraries. Quality minded organizations recognize that they retain ultimate responsibility for ensuring accurate metal verification.<h4>We’ll outline a practical approach for inspecting incoming and outgoing components:</h4><ul><li>Identify unknown metals with grade search</li><li>Verify known grades with a clear match/no match result</li><li>Choose the right tool for each task</li></ul>We’ll demonstrate real world workflows using mobile OES for rapid alloy checks, handheld XRF for quick specification screening, and show how adding grade information enhances results even on stationary OES analyzers.This is rounded out by a brief overview of the SPECTRO metal database – how it works and how it effectively complements the work with the spectrometer.<h4>Why attend:</h4><ul><li>Strengthen quality assurance by aligning verification steps with the right analytical method</li><li>Reduce risk by integrating fast and reliable grade verification into inspection workflows</li><li>Improve decision‑making with structured grade data and proven metal analysis tools</li></ul><h4>Join us live:</h4><ul><li>9:30 AM CET (Berlin); 4:30 PM SGT (Singapore) — Time Slot 1</li><li>11:00 AM EDT (New York); 4:00 PM CET (Berlin) — Time Slot 2</li></ul><blockquote>Presenter: Lars Jenster (Product Support Specialist for the Arc/Spark product line and the handheld XRF SPECTRO xSORT)Lars Jenster offers SPECTRO customers and service engineers worldwide support regarding questions about these instruments.

Choosing Right Method for Reliable Metal Verification

Superalloys enable technologies that operate under extreme conditions. These high‑performance materials withstand high temperatures, mechanical stress, and corrosive environments, but they only deliver their full potential when their chemical composition meets specifications. This live webinar explains what superalloys are, where nickel‑, iron‑, and cobalt‑based grades are used, and why tight chemical tolerances make accurate elemental analysis essential throughout the entire lifecycle of a component.Precise elemental analysis protects performance and safety. Incorrect analysis can reduce component lifetime, can increase the risk of failure during operation, and can lead to costly recalls. In this session, you will learn where metal analysis is required—from incoming inspection and in‑process control to positive material identification and final quality checks—and how analytical requirements change between laboratory environments and direct field use.The webinar concludes by connecting application needs with the right analytical approach. It shows how modern metal analysis solutions based on arc/spark optical emission spectroscopy and X-ray fluorescence technology (XRF) support reliable decision‑making across inspection, sorting, and quality control. By understanding your analytical requirements first, you can confidently select solutions that deliver fast, precise, and reproducible results.<h4>In this webinar, you will learn how to:</h4><ul><li>Understand what makes superalloys unique and why their composition matters</li><li>Apply elemental analysis at critical control points in production and inspection</li><li>Match analytical requirements with the right metal analysis technology</li></ul><h5>Join us live:</h5><ul><li>10:30 AM CEST (Berlin); 4:30 PM SGT (Singapore) — Time Slot 1</li><li>11:00 AM EDT (New York); 5:00 PM CEST (Berlin) — Time Slot 2</li></ul><blockquote>Presenter: Julia KiesslingComing from the Product Support group for the Arc/Spark product line where she has built comprehensive, in depth knowledge of Arc/Spark spectrometry and having recently transferred into Sales, Julia Kiessling provides SPECTRO customers with support and guidance on spark analyzers.

Ensuring Performance in Extreme Applications

Accurate elemental analysis supports confident decisions across metal production, inspection, and verification workflows. When results are required directly at the worksite, analytical performance must remain consistent despite changing conditions, time pressure, and diverse alloy types. Optical emission spectroscopy enables fast, information‑rich metals analysis, including the measurement of critical light elements that influence material properties and compliance.This live webinar explains how modern metal analysis workflows benefit from portable OES‑based approaches. The session describes how on‑site measurements support alloy identification, grade verification, and pass/fail decisions while reducing delays caused by laboratory transport and sample preparation. The presentation also discusses how elemental analysis with LIBS technology complements established metal analysis techniques such as ICP‑OES and ED‑XRF by extending elemental coverage directly into the field.In the final part of the webinar, we´ll introduce the SPECTROPORT LIBS, a portable laser‑induced breakdown spectroscopy analyzer designed to deliver reliable OES performance outside the laboratory. The system applies advanced LIBS technology to support fast, application‑focused elemental analysis where immediate results matter most.<h5>Key takeaways include:</h5><ul><li>How portable OES supports confident elemental analysis of metals in field and production environments</li><li>Why LIBS‑based metal analysis extends elemental coverage beyond handheld XRF limitations</li><li>How application‑driven workflows improve decision‑making speed without sacrificing analytical reliability</li></ul><h4>Join us live:</h4><ul><li>10:30 AM CEST (Berlin); 4:30 PM SGT (Singapore) — Time Slot 1</li><li>11:00 AM EDT (New York); 5:00 PM CEST (Berlin) — Time Slot 2</li></ul><blockquote>Presenter: Marcus FreitMarcus Freit is Product Manager for mobile and stationary metal analyzers at SPECTRO Analytical Instruments.
