For years, environmentalists have known about the contamination of DDT in the ocean waters off the California coast. Montrose Chemical Corporation, the largest producer of DDT in the United States from 1947 until 1982, was infamously dumping chemical waste from their manufacturing process into the sewer system, contaminating the Palos Verde Shelf and eventually requiring the area to be designated as a Superfund site in an attempt to clean up the environmental damage. However, the known DDT contamination did not seem to be enough to explain the abnormally high cancer rates in the local sea lions.

Chasing a hunch, David Valentine, a professor of geochemistry and microbiology at UC Santa Barbara, dove deeper.

Despite the struggles of the past year, Pittcon has chosen to host their annual expo on schedule via a virtual venue. The premier conference on analytical chemistry and scientific instrumentation is needed now more than ever. In an era when scientific breakthroughs can lead to life-saving developments, collaboration and networking among experts is vital. LECO is proud to be joining the first-ever fully-digital Pittcon expo.

LECO has released a revolutionary new data analysis software for GCxGC data: ChromaTOF Tile. This software provides an industry-first data comparison tool that identifies statistically significant differences between classes of samples, reducing days-to- weeks of work down to hours, or even minutes. Based on Dr. Robert Synovec’s tile-based Fisher ratio analysis, ChromaTOF Tile partitions the data into a set of regions (tiles) and compares regionalized data. This allows it to disregard normal variances of alignment shifts to focus on where the actual differences are, so users can stop looking at their data and start actually using it.

Tomatoes are the second-most important vegetable crop in the world (arguments over whether or not it should be called a fruit or a vegetable aside!), and thus it is critically important that tomato yields are kept high. Pesticides are the easiest way to control populations that might destroy crops, but we must make sure that the resulting tomatoes are not contaminated. With GCxGC-TOFMS, recognizing and identifying pesticide residue in tomatoes is easier than ever.

It's that time of year again, when holiday songs play 24/7 on the radio and people start wondering what, exactly, frankincense and myrrh are and why they make good gifts. LECO placed these two oils in a Pegasus® BT 4D to see the difference.

Well what a week and what a great final day! 

Day 4 of the GCxGC Virtual Symposium did not disappoint! The topic of Safety and Security made for another great day of presentations. The quote of the day perhaps was “I like GCxGC because it casts a very broad net on your samples when employing non-targeted analysis strategies.”

Yet another successful day of presentations on Metabolomics and Breath Analysis... Turning Data into Information (thank you Heather)! Note that there are two interesting events on the horizon The Breath Biopsy Conference and the Multidimensional Workshop.

Day 2 of the GCxGC Symposium focused on Petroleum and Fuel with some great discussion!

Day 1 is in the books. What a great start to the 1^st Annual GCxGC Symposium!
