<h4><strong>Do you use results of chemical analyses as a basis for your decisions and judgements?</strong></h4><p>Those of us working in accredited laboratories or dealing with issues concerning the quality of measurements, would like to inform you about some important changes concerning the way the results of measurements are presented. These changes make it easier for you as an end-user to make correct decisions.</p><h4><strong>Nobody is perfect!</strong></h4><p>Results of analyses cannot be perfect! We hope this does not come as a big surprise to you. We use the term <strong>measurement uncertainty </strong>to describe this lack of perfection.</p><h4><strong>The analytical process</strong></h4><p>In each step of the analytical work, from sampling to the final measurement, deviations from the true value occur and measurement conditions vary. We take measures and perform controls regularly to assure that these deviations and variations together are small enough to make sure the end result fulfils your requirements. When we don’t have full information about all of the steps, e.g. when sampling and initial sample preparation are performed by you as a customer, you can assist us by providing detailed information about how that work was performed. Our experts are ready to advise on all matters regarding sampling. Please contact the laboratory beforehand.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Important_information_to_our_customers_concerning_the_quality_of_measurements_2_d885f6b051.jpg" alt="Eurachem: The analytical process" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Important_information_to_our_customers_concerning_the_quality_of_measurements_2_d885f6b051.jpg 139w," sizes="100vw" width="562" height="630"></p><h4><strong>Results should be fit-for-the-purpose</strong></h4><p>The accuracy of the results must of course not be too low nor too high since this would increase the costs. It should be fit for the intended purpose. If you are unsure on what level of accuracy you need, do not hesitate to contact the laboratory.</p><h4><strong>Uncertainty and limiting values</strong></h4><p>Many analyses are made to assure that limiting values are not exceeded. Without information about the measurement uncertainty it may appear to be very easy to make decisions, but these decision may be incorrect, with, e.g. economical consequences when rejecting instead of accepting a product, judicial consequences when returning a verdict of guilty instead of not guilty, or medical consequences when carrying out an unnecessary treatment. There are numerous examples!</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Important_information_to_our_customers_concerning_the_quality_of_measurements_3_f0ef8edc77.jpg" alt="Eurachem: Uncertainty and limiting values" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Important_information_to_our_customers_concerning_the_quality_of_measurements_3_f0ef8edc77.jpg 245w," sizes="100vw" width="932" height="453"></p><p>With a realistic measurement uncertainty the information included in the result becomes much more useful.</p><h4><strong>It will be easier to compare results</strong></h4><p>Most laboratories have until now chosen not to state measurement uncertainty in the test report. Instead, such information has only been given when the customer has asked for it</p><p>In the future, information about the measurement uncertainty will appear more frequently in the test report. It is also possible that you will bump into new and unfamiliar quality terms. This is due to the fact that there are new international guides and standards describing a common and partly new terminology. One of the objectives is to make it easier for you as a customer to compare test results.</p><h4><strong>What could it look like?</strong></h4><p>When reporting the test result we will give the normal information about what we have measured. When the results are followed by uncertainty statements, they are presented as intervals within which the true values are expected to lie with a certain level of confidence (usually 95%). In the example below the lead content is 1.65 ± 0.15 mmol·kg-1, that is between 1.50 and 1.80. The measurement uncertainty is also often reported relatively, in %.</p><ul><li><strong>Total lead content (Pb): </strong>1.65 mmol·kg<sup>-1</sup>&nbsp;</li><li><strong>Measurement uncertainty:</strong> 0.15 mmol·kg<sup>-1</sup> (9.1%)&nbsp;</li></ul><p>The stated uncertainty is an expanded measurement uncertainty (<i>U</i>). It was obtained by multiplying the combined standard uncertainty <i>u<sub>c</sub></i> with a coverage factor <i>k</i> equal to 2. This corresponds approximately to a 95 % confidence interval.</p><h4><strong>All’s well that ends well...</strong></h4><p>The requirements for a consistent way of reporting test results are increasing. Therefore, those of us involved in measurements are eager to assure ourselves that we understand your needs. You will notice this in your contacts with us before, during and after the test assignment. We hope that you will be satisfied with the final result.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Important_information_to_our_customers_concerning_the_quality_of_measurements_4_f870b1a7b8.jpg" alt="Eurachem: All’s well that ends well..." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Important_information_to_our_customers_concerning_the_quality_of_measurements_4_f870b1a7b8.jpg 159w," sizes="100vw" width="713" height="701"></p>

Important information to our customers concerning the quality of measurements

<h4><strong>A comprehensive analysis of renewable fuel testing technologies, automation, and ISO-compliant proximate analysis</strong></h4><p>The growing demand for renewable energy has increased the importance of accurate biofuel characterization. Biomass feedstocks and finished fuels must be carefully analyzed to ensure quality, efficiency, and compliance with international standards. LECO analytical instrumentation supports this work through automated and highly reliable analytical technologies.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/TGA_801_Termogravimetricka_analyza_vlhkosti_popela_tekavych_latek_a_ztraty_zihanim_b73c4cf493.jpg" alt="LECO: Advancing Biofuel Characterization with LECO Analytical Instrumentation: LECO’s TGA801, used for automated biofuel analysis." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_TGA_801_Termogravimetricka_analyza_vlhkosti_popela_tekavych_latek_a_ztraty_zihanim_b73c4cf493.jpg 245w," sizes="100vw" width="1164" height="435"></p><h3><strong>Automated Proximate Analysis with LECO’s TGA801</strong></h3><p>The<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1877"> <strong>LECO TGA801 thermogravimetric analyzer</strong> </a>is designed for automated determination of moisture, volatile matter, and ash content in solid fuels. The system can analyze up to 19 samples simultaneously and combine all three parameters into one automated run, improving efficiency and reproducibility.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_31e96f1c96.jpg" alt="LECO Advancing Biofuel Characterization with LECO Analytical Instrumentation: TGA801 system with ceramic turntable and crucibles for ISO 18123 volatile matter determination." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_31e96f1c96.jpg 235w," sizes="100vw" width="860" height="573"></p><h3><strong>Comparison with ISO Reference Methods</strong></h3><p>To validate the performance of the automated TGA801 system, comparative studies were conducted using internationally recognized ISO reference methods. Moisture determination was compared with ISO 18134, ash content with ISO 18122, and volatile matter with ISO 18123. These standards prescribe specific temperatures and analytical procedures, but also permit automated systems if equivalent performance can be demonstrated.</p><p>The comparison included a broad range of materials such as wood pellets, peat, coal, plastics, and waste-derived fuels. Moisture and ash results generated by the TGA801 showed extremely close agreement with the manual ISO procedures. This strong correlation confirms that automated thermogravimetric analysis can provide the same reliability as conventional methods while greatly increasing throughput and reducing labor requirements.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_2_3887128788.jpg" alt="LECO: Advancing Biofuel Characterization with LECO Analytical Instrumentation: ISO method crucibles for manual volatile determination." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_2_3887128788.jpg 172w," sizes="100vw" width="1264" height="1145"></p><h3><strong>Volatile Matter Correlation Results</strong></h3><p>For volatile matter analysis, both ISO and TGA procedures measure mass loss during a fixed period at 900 °C. The TGA method introduces an additional heating ramp from the moisture determination step at approximately 105 °C to the higher volatile matter temperature. Despite this procedural difference, the resulting data demonstrated excellent agreement.</p><p>Testing performed on wood pellets showed a strong linear relationship between the ISO and TGA methods with an R² value of approximately 0.94. The maximum deviation observed was only 1.06%, while the average difference between methods was approximately 0.1%. These results confirm the ability of the TGA801 to produce highly accurate volatile matter measurements across a variety of biomass and fuel matrices.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_2_40f7189cef.jpg" alt="LECO Advancing Biofuel Characterization with LECO Analytical Instrumentation: Correlation and comparative data between ISO methods and LECO TGA analysis." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_2_40f7189cef.jpg 172w," sizes="100vw" width="1065" height="967"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_1_7519e8e646.jpg" alt="LECO Advancing Biofuel Characterization with LECO Analytical Instrumentation: Correlation and comparative data between ISO methods and LECO TGA analysis." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_LECO_Advancing_Biofuel_Characterization_with_LECO_Analytical_Instrumentation_1_7519e8e646.jpg 228w," sizes="100vw" width="1641" height="1120"></p><h3><strong>Advantages of Automated Biofuel Analysis</strong></h3><ul><li>High sample throughput with simultaneous multi-sample analysis.</li><li>Fully automated workflows reducing operator involvement.</li><li>Integrated determination of moisture, ash, and volatile matter in one run.</li><li>Excellent reproducibility and data consistency.</li><li>Strong agreement with ISO reference methods without additional calibration.</li><li>Improved data security and laboratory efficiency.</li><li>Suitable for research laboratories, industrial quality control, and fuel certification.</li></ul><h3><strong>Automate Your Lab Today</strong></h3><p>LECO analytical instrumentation provides a comprehensive solution for modern biofuel characterization.
