Happy Farai-Day! A Measured Science Episode

Here at LECO, we have been celebrating Farai-Day (Fri-day) every week for fourteen years! Our new Director of Separation Science Customer Success, Farai Rukunda has been a force of positivity and solutions ever since he accepted his first position as a training specialist. Farai joined host Andrew Storey on LECO's podcast: Measured Science.

Gypsum and the TGA: Analyzing FGD Solids

The thermogravimetric analyses of the TGA801 and its predecessors can do more than measure organic materials. With its ability to handle large, gram-sized samples, the TGA801 has become an invaluable tool for the monitoring of industrial byproducts, such as flue-gas desulfurization (FGD) solids.

Beneath the Peel: Characterizing Citrus Aromas with GC-TOFMS

Both lemons and limes have strong citrus odors, but the difference between these fruits is wide at an analyte level. Identifying these differences is not as easy as it first seems, but the Pegasus® BT and the automated data processing software included in its ChromaTOF® brand software make finding the peaks easy.

Slice Time off your Meat Moisture Analyses with the TGM800

As with all foodstuffs for human consumption, meat is highly regulated. Determining its makeup is essential to confirming a safe product. The faster regulatory analyses can be performed, the quicker you can confirm the quality of your product and maintain production speed.

Determining the moisture content of meat is one such analysis that helps identify the quality and safety of the meat in question. Moisture content can control the texture, taste, and microbial stability of the meat. It also determines the level of retained water, additive solutions for flavoring, and the leanness of meat.

Towards an Even Better Tasting Veggie Burger with GCxGC-MS

Sustainability is on everybody’s mind these days. Companies want to create products that are better for the environment and consume fewer resources. Unilever is no exception. This forward-thinking flavor company has recently been pushing to develop new and delicious plant-based protein substitutes that are more sustainable than meat-based protein but no less healthy (or, preferably, even more healthy!). However, as Unilever scientists Hans-Gerd Janssen and Ed Rosing explain, nature made a pretty delicious protein in the form of meat, with a very distinct flavor and mouth-feel. Creating a substitute isn’t easy.

A Cleaner Source: StayClean® Ion Source

The pressure to save money is everywhere these days. The changes due to COVID-19 have only exacerbated the age-old question your own lab has probably asked: how can we cut costs? One hidden expense in a GC-MS lab setting is the cost of cleaning your instrument's ion source.

Determining a Full Field of Carbon and Nitrogen with the 828 Series

A web of factors contributes to a good crop, but the importance of carbon and nitrogen cannot be overstated. From soil to fertilizer to the plant matter itself, the mix of carbon and nitrogen play key roles in the development and growth of the plant. Knowing the carbon and nitrogen levels in every aspect of your field can help you maintain quality control over the end result.

Microplastics: Seeing the Details with GCxGC

Microplastics are a ubiquitous presence in the world, found from Arctic snow to Antarctic ice and everywhere in between. There are trillions of microplastic particles floating on surface water, and everyone from infants to adults are presumed to be ingesting anywhere from dozens to tens of thousands of these particles every day. But the science of microplastics, especially the incredibly tiny, potentially-cell-disrupting nanoplastics, is only just beginning. The effects of these microplastics isn't well known, largely because the scale of microplastics isn't well known. They are, by definition, difficult to see.

Unless you're looking in a second dimension.

Determining Total and Soluble Protein with the FP828

98% of the world's soybean meal is used as animal feed, principally as a protein supplement. With the importance of protein in animal growth and development, knowing what's in your soybean meal is vitally important. There is more to protein than the crude protein concentration number, however. If an animal can't digest the protein, if it isn't a 'soluble' protein, then it doesn't actually provide the nutritional value needed. LECO's FP828 is capable of both total and soluble protein analyses.

Folded Flight Path®: Ten Years of High Resolution

The first Time-of-Flight (TOF) mass spectrometer was proposed in 1946, and the design has been refined and iterated upon ever since. With an unlimited mass range visible in each spectrum and a high spectral generation speed, the advantages of TOF mass spectrometry were immediately clear. Though the instruments improved, they did eventually hit physical limitations that restricted the resolving power. More work had to be done.
