Balanced Soil: Carbon, Nitrogen, and Sulfur Determination with the CNS928

Well-balanced crops require well-balanced soil. While carbon may be the most essential element for organic life, the right ratio of nitrogen and sulfur in the soil along with the carbon can really influence the speed and strength of plant development and growth. With a macro combustion carbon, nitrogen, and sulfur determinator such as LECO's CNS928, those ratios can be discovered easily through fast and precise analysis.

Christmas Coal and Quality Determination with the TGA801

There’s coal and then there’s coal, and Santa Claus knows the difference. When preparing coal for the stockings of naughty boys and girls on Christmas Eve, Santa is not about to waste high quality, high-carbon material on children who have been bad. But while Santa is magic and can tell in an instant which coal is appropriate, how can those of us not lucky enough to work out of the North Pole determine our coal quality?

Standard Oven Drying Methods vs. TGM800: Direct Moisture Determination

Working with grains meant a lot of thermogravimetric analyses, but standard oven drying methods were incredibly time-consuming. Depending on the flour matrix, oven times could range from 1 hour to 17. Whole grains could take a full 72 hours. LECO Africa reached out to Jolanda Nortjé, Laboratory Manager of The Southern African Grain Laboratory (SAGL), with a suggestion of a better way, and Nortjé was happy to give it a try. She agreed to participate in a comparison of a primary moisture loss-on-drying determination using the TGM800 and standard oven drying methods.

A Tip on Met Tips

Let's be honest, metallography is not exactly the biggest field out there. If you're struggling with your computer, you can ask the internet "why did this error message come up?" and get some troubleshooting advice, but if you try typing "Why do I have radial cracks?" into a search engine, you'll more likely end up with an article about tomatoes than you will an explanation of what could cause a radial crack in a prepared mount and how to prevent it.

That's where we come in.

Medical Diagnosis using Breath Analysis and GCxGC-TOFMS: Optimizing Data for Accurate Treatment

At our ASMS breakfast seminars, Jean-François (Jef) Focant, Head of the Department of Chemistry and Director of the Organic and Biological Analytical Chemistry group at the University of Liège, Belgium, spoke about using our Pegasus® BT 4D and Pegasus® GC-HRT 4D for GCxGC-TOFMS on the breath of asthma patients to improve asthma treatment. Before diving into the blood and sputum, Jef first educated us on the importance of optimizing your data.

ASMS in Review: Frank Dorman, Penn State

Frank Dorman, an Associate Professor of Biochemistry and Molecular Biology at Penn State University, spoke at our ASMS breakfast seminar about his experience using our Pegasus BT 4D benchtop GCxGC-TOFMS to analyze environmental contamination in the Susquehanna river. Due to the increasing chemical complexity of the environment, GCxGC-TOFMS with its Non-Targeted compound analysis is the ideal technology for these intricate samples.

Take Your GC-MS Analysis One Step Further

What if you could take your GC-MS analysis one step further by easily adding a second dimension of separation? Our new FLUX™ GCxGC flow modulator uses a diverting flow technique (rather than industry-standard thermal modulation), eliminating the need for costly cryogens, and making GCxGC more cost-effective and routine to the everyday analyst.
