Gypsum and the TGA: Analyzing FGD Solids

July 23, 2021

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.

A Cleaner Source: StayClean® Ion Source

July 16, 2021

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

July 1, 2021

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

June 25, 2021

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

June 11, 2021

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

June 4, 2021

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.

The TGA: Macro and Micro

May 21, 2021

Thermogravimetric analysis (TGA) first started in the early 20th century, and while the technology has advanced, the basic principles remain the same. With TGA, the rate of change of reactions in the chemical and physical properties of materials as functions of temperature or time is what is used to assess the properties of the sample materials. Most TGA these days is done with either micro TGAs (using milligram-size samples) or macro TGAs (using gram-size samples).
