LOI data helps identify moisture and carbonation, which can negatively impact cement performance. With automated split loss on ignition using\u00a0<a href=\"https:\/\/dev26.lecowebtest.com\/fr\/instrument\/analyseur-thermogravimetrique-tga801\/\" data-type=\"instrument\" data-id=\"2243\">LECO\u2019s TGA801<\/a>, laboratories can obtain detailed LOI results at two distinct temperatures in a single, uninterrupted run, improving efficiency and consistency in cement LOI testing.<\/p>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading is-style-h2-style\">Understanding Split LOI Analysis for Cement Applications<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional loss on ignition cement analysis measures total mass loss after heating a sample to high temperature (often up to 1,000 \u00b0C). While this provides valuable information, it does not distinguish between different sources of mass loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Split LOI analysis addresses this by determining mass loss at two specific temperature ranges. In cement applications, these temperatures are typically:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>550 \u00b0C<\/strong>\u2014this temperature is associated with moisture and volatile loss.<\/li>\n\n\n\n<li><strong>950 \u00b0C<\/strong>\u2014this temperature is associated with carbonate decomposition and carbon dioxide release.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">By calculating the difference in residue mass between these two steps, laboratories can estimate carbon dioxide and moisture content to gain a better understanding of their cement composition. Split LOI is widely used to monitor cement quality and detect issues such as pre-hydration or carbonation caused by improper handling or prolonged storage.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading is-style-h2-style\">Automated Split Loss on Ignition with the TGA801<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large is-style-rounded-full-width\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/scientist-loading-coal-samples-tga801-1024x576.webp\" alt=\"Scientifique chargeant des \u00e9chantillons dans un analyseur thermogravim\u00e9trique\" class=\"wp-image-2869\" srcset=\"https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/scientist-loading-coal-samples-tga801-1024x576.webp 1024w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/scientist-loading-coal-samples-tga801-300x169.webp 300w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/scientist-loading-coal-samples-tga801-768x432.webp 768w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/scientist-loading-coal-samples-tga801-18x10.webp 18w, https:\/\/dev26.lecowebtest.com\/wp-content\/uploads\/2026\/03\/scientist-loading-coal-samples-tga801.webp 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The\u00a0<a href=\"https:\/\/dev26.lecowebtest.com\/fr\/instrument\/analyseur-thermogravimetrique-tga801\/\" data-type=\"instrument\" data-id=\"2243\">TGA801\u00a0is a macro thermogravimetric analyzer<\/a> designed to simplify and speed up split LOI testing for cement and other materials. One of its key advantages is the ability to perform automated split LOI using just one method and only one user interaction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once samples are loaded and the analysis is started, the TGA801 automatically heats the sample from ambient temperature to 550 \u00b0C and records the LOI. It then continues directly to 950 \u00b0C and records the second LOI value. From there, it calculates split and total LOI without stopping the run, meaning there is no rehandling of samples. This single\u2011interaction split LOI workflow eliminates the need for multiple methods or manual intervention between temperature steps, reducing analysis time and minimizing any opportunities for error.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading is-style-default\">Automation Equals Speed<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Automating split LOI analysis can significantly improve laboratory productivity. The TGA801 allows up to 19 cement samples to be analyzed simultaneously, making it well-suited for high\u2011throughput cement quality control testing. By removing manual steps between 550 \u00b0C and 950 \u00b0C, the TGA801 streamlines analyses, allowing labs to focus on interpreting results rather than managing the process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading is-style-default\">Consistent, Reliable Results<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Consistency is essential in automated LOI testing, especially when results support cement chemical analysis performed under methods <a href=\"https:\/\/store.astm.org\/standards\/c114\" target=\"_blank\" rel=\"noopener\">such as ASTM C114<\/a>. With the TGA801, all samples follow the same programmed method parameters, including temperature ramps, hold times, and airflow. This standardized approach supports improved repeatability between runs, reduces operator\u2011to\u2011operator variability, and thus, invokes greater confidence in split LOI and total LOI data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reliable split loss on ignition results help cement producers monitor raw materials, verify product quality, and support corrective actions when deviations occur.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-1ea9787f wp-block-group-is-layout-constrained\" style=\"margin-top:48px\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"margin-top:0\">\n<hr class=\"wp-block-separator has-text-color has-sl-1-color has-alpha-channel-opacity has-sl-1-background-color has-background has-base-100-color has-base-100-background-color is-style-default\" style=\"margin-top:60px;margin-bottom:60px\">\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading is-style-h4-style\">A Smarter Approach to Cement LOI Analysis<\/h2>\n\n\n\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-67eca248 wp-block-group-is-layout-flex\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"wp-block-paragraph\">For laboratories seeking a more efficient way to perform split loss on ignition analysis, LECO\u2019s TGA801 delivers a clear advantage.
