HPLC experts at EAS Booth 524

We’re proud of the depth and breadth of knowledge we have in the field of chromatography and the many friends we have in the field.

Today at EAS, we’re joined by the good people at Separations Methods Technology – pictured here is Richard Plaugher talking with Steven Miles. Come on by EAS Booth 524 and share your Thin Layer Chromatography and HPLC stories.

HPLC reveals difference between freshly brewed and bottled tea

Our friends at Chromatography Today published an Joe Tea resized 600interesting finding recently about how HPLC has been used to examine the chemical differences between fresh-brewed tea and bottled tea.

Here’s an excerpt:

Dr Shiming Li, a natural product chemist at New Jersey biotechnology firm WellGen, led a team using HPLC to analyse polyphenol levels in fresh tea and in bottled health drinks.

In some cases, the bottled beverages had levels of the antioxidants equivalent to around five per cent of the quantity seen in a single freshly brewed cup of either green or black tea.

University of Delaware Class on Thin Layer Chromatography

Karen Brinker and Leslie Allshouse graciously allowed us to join them recently as they led their University of Delaware

UD class

Clinical Physiological Chemistry II class through a drug testing procedure using Thin Layer Chromatography.

Unfortunately, our sound engineer was off his game that day – the background noise you hear in the video is blow driers being used to dry the TLC plates.

Many thanks to Karen and Leslie for letting us be a part of the class! 

Talking HPLC Columns with Dr. David Fatunmbi

The new Color HPLC Columns continue to draw attention here at the Eastern Analytical Symposium.Micky Jones, Steven Miles, Dr. David Fatunmbi

Answering HPLC questionsBesides the practical aspect of knowing which packing material you have inside a column based on the color outside, our HPLC columns utilize proprietary bonding technologies from Separation Methods Technologies that result in bonded phase coverage approaching 100%.

Dr. David Fatunmbi of SMT is the person responsible for this exciting development and has spent some time answering questions from visitors to our booth and helping people out with their HPLC issues.
