Advancing Clean Steel Manufacturing with Modern Technologies

Non-metallic inclusions are of considerable importance for the<a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/us/en/home/industrial/manufacturing-processing/steel-manufacturing.html?icid=CAD_blog_metals_2023Aug"> steel industry</a> due to the dramatic influence that even small amounts of them may have on properties, mechanical and otherwise, of the metal or on the production process itself. Inclusions can have positive effects and may increase the value of the steel, but most often inclusions signify quality problems and reduced value.&nbsp;This is true in particular for an increasing number of steel types used in demanding applications and industries, such as the automotive, aerospace, nuclear, offshore and pipeline industries. In many cases, inclusions also signify issues in the steel manufacturing process (e.g., nozzle clogging). Therefore for many companies, a main objective is to keep critical inclusions under very tight control during production.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Can_OES_Provide_Inclusion_Analysis_during_Steel_Production_72f6719947.jpg" alt="Thermo Fisher Scientific: Can OES Provide Inclusion Analysis during Steel Production?" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Can_OES_Provide_Inclusion_Analysis_during_Steel_Production_72f6719947.jpg 235w," sizes="100vw" width="768" height="510">The modern reference for inclusion analysis is the SEM/EDX (scanning electron microscope coupled with energy dispersive X-ray fluorescence spectroscopy). This analytical process takes typically several hours, including sample preparation and interpretation, which is far too long to be applicable to production control.Within recent years we’ve seen the development of extremely fast and economical<a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/order/catalog/product/IQLAAHGABDFAOOMBOD?icid=CAD_blog_metals_2023Aug">&nbsp;OES (optical emission spectrometry) methods</a>&nbsp;which are able to provide inclusion information even during the <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/us/en/home/industrial/manufacturing-processing/steel-manufacturing.html?icid=CAD_blog_metals_2023Aug">steel production</a> process. The method uses the principle of Single Spark Acquisition (SSA), where signals from the individual “single sparks” are not summed as in conventional OES acquisition, but processed with special algorithms. Several aspects of these methods explain the continuously growing interest from the steel community:<ul><li>Availability of inclusion information in near-real time during the production of steel — The <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/order/catalog/product/IQLAAHGABDFAOOMBOD?icid=CAD_blog_metals_2023Aug">inclusion analysis,</a> which is performed in combination with the classical spectrochemical analysis, does not extend the time needed for the traditional OES analysis.</li><li>Drastic reduction of investment costs — The inclusion analysis is performed with the same instrumentation used for production process control.</li><li>Extremely short time for inclusion analysis — A two-run combined analysis takes about 1 minute; it is possible to analyze more than 30 samples per hour.</li><li>No additional cost or time for operations — Sample preparation, maintenance, and service operations are the same as for a standard OES instrument.</li></ul>The most advanced methods to date can determine the&nbsp;quantitative size (distribution) analysis&nbsp;for various types of inclusions, as well as the&nbsp;quantitative determination of oxygen&nbsp;down to a few ppm in killed steels.The high speed of these analytical methods makes them uniquely suited for the control of inclusions during production. They can of course also be extremely beneficial (and simple to implement) when seeking to <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/order/catalog/product/IQLAAHGABDFAOOMBOD?icid=CAD_blog_metals_2023Aug">monitor inclusions</a> in finished or semi-finished steel products.<blockquote>Additional Resources:&nbsp;<ul><li>Product specifications: <a target="_blank" rel="noopener noreferrer" href="https://assets.thermofisher.com/TFS-Assets%2FCAD%2FSpecification-Sheets%2Farl-ispark-8860-ps41437.pdf?icid=CAD_blog_metals_2023Aug">ARL iSpark 8860 Inclusion Analyzer</a></li><li>Interview/Article: <a target="_blank" rel="noopener noreferrer" href="https://www.azom.com/article.aspx?ArticleID=21497">Real-time Analysis of Steel Production Samples</a></li></ul></blockquote>&nbsp;

Shimadzu / ASMS: Arsenic Speciation in Rice and Rice Products using LC-ICP-MS: A Sensitive and Reliable Approach by Shimadzu&nbsp;</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/ASMS_2025_THP_065_99cfe0ebbb.pdf">Full PDF for download</a></li></ul>Arsenic toxicity is a major public health concern, particularly in drinking water, leading to strict regulatory limits worldwide. While total arsenic has traditionally been measured, its toxicity largely depends on its chemical form with inorganic species Arsenite and Arsenate (As(III) and As(V)) being highly toxic and carcinogenic, and organic forms monosodium methyl arsenate (MMA) and disodium methyl arsenate (DMA) displayed in fig. 1, considered less harmful. Speciation analysis is therefore essential for accurate risk assessment.&nbsp;Rice and rice-based products are of particular concern, as rice can efficiently accumulate inorganic arsenic from the environment. In response, the European Union established maximum residue levels (MRLs) for inorganic arsenic in rice under Commission Regulation (EU) 2015/1006, highlighting the need for precise speciation.&nbsp;To address this, advanced techniques like liquid chromatography coupled with inductively coupled plasma mass spectrometry (LC-ICPMS) are employed. LC-ICPMS provides high sensitivity and specificity for arsenic species determination, ensuring regulatory compliance and protecting consumer health.&nbsp;This study presents the effective use of Shimadzu’s <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=LC-ICPMS-2050+LF">LC-ICPMS-2050 LF</a> system for arsenic speciation in rice and related products.<h4>Methods and Materials</h4>All standard stock solutions are prepared as specified in the LC-ICP-MS Method Package for Arsenic Speciation Analysis Type-2 by Shimadzu, Japan. Seven levels of mixed calibration standards are prepared and injected for the quantification of arsenic species. Calibration curves are generated using the external standard calibration method with a 1/l weighted regression. All samples are prepared in duplicate to verify method performance. Additionally, two spiked samples containing only inorganic arsenic standards are included to evaluate the extraction efficiency of the method.&nbsp;The Shimadzu <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=ICPMS-2050+LF">ICPMS-2050 LF</a>, coupled with the Nexera LC series (Fig. 2), manufactured by Shimadzu Corporation, Japan, is used to separate and quantify the different arsenic species present in the samples.<h4>Conclusion&nbsp;</h4><ul><li>The extraction procedure employed effectively ensures the recovery of inorganic and organic arsenic species from various sample types, including both raw and processed materials.&nbsp;</li><li>A highly sensitive method based on hyphenated techniques, specifically LC-ICPMS, is developed for the speciation and quantification of arsenic using the Shimadzu ICPMS-2050 LF coupled with a Nexera inert LC system.</li></ul><h3>3. Thermo Fisher Scientific: EDXRF analysis of coal fly ash as loose powders Ling Yok Ung, Application Specialist</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/edxrf_analysis_of_coal_fly_ash_as_loose_powders_an41971_en_2960bf7ad9.pdf">Full PDF for download</a></li></ul>All the waste that remains after coal is burned, often in a coalfired power station, is referred to as coal ash. Coal ash may contain lead, mercury, arsenic and many other heavy metals. Fly ash and bottom ash are two subcategories of coal ash, typically separated based on particle size.&nbsp;More than half of coal leftovers are fly ash, the most abundant and well-known component. Particles of fly ash, the lightest type of coal ash, “fly” up into a power plant’s exhaust stacks because they are so light. About 99 % of the ash are captured by filters inside the stacks, which draw it in with opposing electrical charges. Fly ash can be recycled. The fine particles are a perfect material for wallboard and concrete because they bond together and solidify, especially when combined with water.&nbsp;But fly ash from coal is also a dangerous industrial solid waste. The natural environment and human health are seriously threatened by its excessive worldwide production, inappropriate disposal methods, underutilization, and lack of knowledge about its inherent risks. Therefore, a method that is quick, precise, and accurate, is required to quantify coal fly ash. Many companies use X-ray fluorescence spectrometry (XRF) as a preferred technology for process and quality control since it is a proven analytical approach that can accurately assess the chemical composition of materials with limited sample preparation.<h4>Instrumentation&nbsp;</h4>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1209">Thermo Scientific™ ARL™ QUANT’X EDXRF Spectrometer</a> is equipped with a Silicon Drift Detector (SDD) and a 50 Watt Rh or Ag target X-ray tube which is air cooled with a maximum excitation v The Thermo Scientific™ ARL QUANT’X™ EDXRF Spectrometer is equipped with the following features: and radiation of heat in our atmosphere; N2 and O2 which are present in much higher concentrations do not have this same characteristic effect.

This compact instrument allows for reliable and fast analysis of coal fly ash. Accuracy and repeatability results show that satisfactory results are obtainable for an analysis of loose powder in vacuum. This is a significant advantage for simple sample preparation while providing good accuracy &amp; precision.
