ChromaTOF® Tile for GCxGC Analyses

January 29, 2021

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.

Deciphering Complex Tomatoes and Pesticide Residues with GCxGC-TOFMS

January 26, 2021

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.

The Difference between Frankincense and Myrrh

December 16, 2020

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.

September 18, 2020

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.”

Beyond the MOSH/MOAH Hump

August 7, 2020

In Europe, food contamination by Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) is a growing concern and one that is starting to gain attention in North America. There is not enough data yet to know for sure if all MOSH and MOAH contamination is harmful, but some MOSH has been proven carcinogenic, and some MOAH have caused complications in lab mice and selective build-up in the human body. In order to better understand the effects of these hydrocarbons, it is first important to determine the presence and types of MOSH and MOAH in food samples.
