We Don't Know What We Don't Know (But GCxGC Can Find It)

May 27, 2022

LECO recently concluded a webinar series on agricultural applications of our instruments with a presentation by Dr Frank Dorman of Dartmouth College, Department of Chemistry, formerly of Penn State University, Department of Biochemistry and Molecular Biology. While at Penn State, Frank worked on an environmental forensic investigation of wastewater applied to agricultural fields.

Designed for Speed: Fast GC

May 6, 2022

Even the best-trained experts can only move as fast as their equipment will allow, and as helium prices increase and supplies drop, the fast spectral acquisition speeds of GC-TOFMS instruments stand ready to reap the benefits of fast GC separations afforded by utilizing hydrogen carrier gas.

While the advantages of helium as a carrier gas for mass spectrometers have long been known, it is a limited natural resource. On the other hand, hydrogen gas generators can be installed in any lab for a constant supply and, conveniently, increased chromatographic speeds.

Sticking to Boards: Carbon and Nitrogen Determination in Adhesives

February 18, 2022

Wood is a strong, durable, and renewable resource that is popular in construction, especially for furniture, but it grows more expensive year by year. Engineered wood products such as medium-density fibreboard (MDF) or particle board are much more economical solutions that are common in many homes around the world. However, there is a certain danger in their manufacture that is important to monitor.

Don't Suffer your Sulfur in Portland Cement with the SC832

January 28, 2022

Portland cement, one of the most ubiquitous building materials in the world, is not all the same. There are five standardized types of Portland cement classified by the ASTM C150 standard, and each of these different types have different best-use cases. Part of what distinguishes these types of cement is the concentrations of carbon and sulfur in the precursor materials. Sulfur is especially important in determining the final chemical resistances of the Portland cement, so knowing the sulfur concentration is critical to correctly determining the type and quality of the final material.

Clinker Concerns: A Metallographic Analysis of Cement

January 14, 2022

There is no question about it: concrete is the most ubiquitous and versatile building material in the world. While the basic recipe is simple—cement, aggregate, water, and air—the variations and additions to this recipe can create infinite types of concrete. Knowing that your concrete is capable of withstanding the forces that will be acting upon it is vital to the success of any concrete construction process.

Death, Disease, and Mummies: A Virtual GC/MS Symposium

October 8, 2021

For many, fear of the unknown can be paralyzing. A smell, a taste, an object that cannot be identified... for most people, it is a warning to stay away.

For mass spectrometrists, it is an invitation.

To celebrate the season, LECO is taking a look at the spookier side of mass spectrometry with a virtual symposium celebrating science beyond the grave.

Building Strong Foundations Webinars

September 3, 2021

No matter where you are in the urban landscape, you are never more than a few feet from cement. Cement forms the basis of virtually the entire world’s infrastructure. It is an impressively cheap binder that enables a wide variety of building materials. Despite its ubiquity, it is a surprisingly complex mixture of a balance of ingredients such as lime, silica, alumina and more. Knowing what is in your cement is a fundamental check of its quality and strength.
