Thin Layer Chromatography in India

This is our company’s first trip to India – and we have a strong feeling it won’t be our last.

From enjoying the incredible sights, sounds, and food to meeting some truly incredible peoplebreakfast in Bngalore and exploring exciting new possibilities in chromatography, we are enthralled with India!

In just one day we had the privilege of enjoying breakfast with officials from the Consulate General and met with the men and women of S.V. Scientific – a great company that distributes our chromatography products.

Stay tuned – more updates to come from Bangalore and Mumbai.

Our Company is 50 years old now!

Fifty Years – five decades – half a century – yep, we’ve been manufacturing Thin Layer Chromatography plates for a while!

September 14, 1961 – our company was founded in Matt Lamkin’s basement – today we’re producing thousands of plates a week and distributing them to more than 60 countries around the world!

To help mark the occasion, we got some recognition from our friends at the Delaware BioScience Association – and a very nice letter from Governor Jack Markell.

Was Tsvet really the first to use chromatography?

According to most sources, Russian Botanist Mikhail Tsvet was the first person to use chromatography (in fact, he coined the term) in 1901 when seperating an extract of green leaves through a glass tube filled with calcium carbonate.

But according to an article published in the Montreal Gazette, it appears two German scientists may have been doing some chromatography nearly 40 years earlier…

The Annual Review of Progress in Chemistry published in German in 1862, about 40 years before Tsvet’s experiment, includes the following lines: “Friedrich Goppelsroder has shown that (Christian) Schönbein’s observation, whereby solutions of various substances are aspired with very different rates and intensities by filter paper, can be used to separate and distinguish different dyes contained in the solution.” That is a clear a description of what we now call “paper chromatography,” yet Goppelsroder and Christian Friedrich Schönbein hardly ever get a mention when it comes to the invention of the technique.

Seriously, we recommend reading the entire article – it’s a truly great read.

The National Export Initiative

We were proud to be asked to be a part of the National IMG 20110513 104935 resized 600Export Initiative in Wilmington, Delaware on Friday, May 13, 2011.

The event featured U.S. Secretary of Commerce Gary Locke, U.S. Senator Chris Coons, Delaware Governor Jack Markell, the World Trade Center Delaware, the U.S. Department of Commerce, the Delaware office of International Trade, and many more.

As a company that exports chromatography supplies to more than 40 countries on six continents (still working on Antarctica), we are happy to share what we can with other companies about best practices concerning International Trade.

Here’s a series of videos from throughout the day:

Analtech Technical Director Featured in LCGC Roundtable

Our Technical Director, Ned Dugan, recently participated in a Ned Dugandiscussion about Thin Layer Chromatography with Ling Bei and Dave Lentz of EMD Chemicals and the editors of LCGC.

Here’s a couple of excerpts:


What developments have you the most excited or intrigued in TLC?

Dugan: There are two categories that come to mind. First, I’m excited to see TLC making a significant difference in people lives, whether that’s protecting people from counterfeit anti-malarial medication or helping law enforcement catch criminals through ink analysis.

The second category involves applications that a person just wouldn’t normally think about. For example, using TLC to determine the difference between diesel smokes (whether the smoke contains a potent carcinogen or not). That makes me wonder just how TLC is going to be applied in the next 5–10 years.

Bei & Lentz: Anything that will help spread the word that TLC does more than you think and that it can help solve a lot of modern problems.

Continued automation and software breakthroughs have allowed TLC users to control variables and achieve better reproducibility and faster results and to finally develop rugged, validated methods. Now it also allows them to interface with lab data and LIMS systems.

What are the pros and cons of using TLC in a food safety lab? How about in an environmental lab?

Dugan: The advantages of using TLC in food safety and environmental labs are the same as using TLC in any lab. It is an easy-to-use method that can accommodate multiple samples and standards simultaneously. It is inexpensive and affords (pun intended) the analyst a snapshot into the constituents of a sample matrix in a way that other forms of chromatography simply can not provide.

The downside of TLC is that it is only one tool in the toolbox. One tool won’t fix all problems. It takes the collection of tools to effectively manage an analytical laboratory.

Bei & Lentz: Common advantages of TLC for both types of labs include little or no cleanup even for some “dirty” samples, multiple parallel separations under identical run conditions for high throughput, and very much lower initial and consumable costs compared to HPLC or GC. Plus, every component of even extremely complex food or environmental samples is somewhere on the developed TLC plate and can be isolated using specific visualization or indicator reagents, then scraped off and recovered for further analysis or purification.

What do you hope and expect to see in the future for TLC?

Dugan: What I expect to see is TLC being used more often for the versatile tool that it is in multiple fields of science. I hope to see TLC applied to even more areas that would make a significant difference in the world. For example, helping to develop and test potential alternatives to fossil fuels or developing new methods for cleaning water supplies.
