Why the USDA uses Analtech TLC Plates

William Koskinen is a Soil Scientist with the U.S. Department of Agriculture. His current research interests include soil chemistry/biochemistry with an emphasis in determination and quantification of the mechanisms and factors controlling the degradation, movement, and activity of pesticides and their metabolites in soil; and use this knowledge to increase pesticide efficacy in agricultural production systems and decrease the risk of ground and surface water contamination.

William Koskinen has been performing Thin Layer Chromatography separations for about 30 years – and he uses Analtech Thin Layer Chromatography Plates.

This is Really HOT!

Did you know that it was Thin Layer Chromatography that first allowed us to measure exactly how “hot” spicy food is?hot pepper

The presence of other compounds related to capsaicin in Capsicum extracts was detected by Kosuge et al. (1961) and Friedrich and Rangoonwala (1965) using paper and thin-layer chromatography methods respectively. Kosuge named the new compound in his sample dihydrocapsaicin, which was observed present in a ratio of 3 : 7 with capsaicin. Other investigations by Todd and Perun (1961), Morrison (1967), Hollo eta!. (1969) and Hartman (1970) also indicated the occur- rence of one or more compounds related to capsaicin in extracts of products.

We love to see Chromatography written about all over the place. So whenever something good is brought to our attention, we want to pass it along to you.

This is from Biochemistry Practicals:

In this practical the lipids present in egg yolk were separated through absorption chromatography using a TLC plate. The concept is similar to paper chromatography, a plate containing a thin hydrophilic layer called a matrix is used, and a non polar solvent is allowed to move up the plate through capillary action. Thus more polar lipids will move more slowly than non polar lipids.

Analtech e-mail campaign recognized as one of the best

In 2008, SelectScience launched 155 e-mail campaigns to members of the science community.
Adventures of Ana
One of those campaigns was for the release of “The Adventures of Ana L’Tech.”

While at Pittcon, we at Analtech learned that campaign was measured to be the second most successful e-mail campaign of the year by SelectScience.

Jay Leech of SelectScience explained that the words and images in the campaign led more people to “click-through” to view the video than all but one other campaign.

We at Analtech are grateful to all who recieved that SelectScience e-mail and clicked on the link to watch “The Adventures of Ana L’Tech.”
