ES Notes November 2011

BREAKING NEWS: This special report is brought to you from Eastern Analytical Symposium 2011 in Somerset, New Jersey where David Kohler of ES Industries commented "we have met many friends and colleagues many of whom were very interested in the brand new article in LCGC titled "A Systematic Study of Achiral Stationary Phases Using Analytes Selected with a Molecular Diversity Model"

The article co-authored by Ray McClain - Senior Research Associate at Merck's West Point, Pennsylvania facility and our own Matt Przybyciel - VP and Technical Director of ES Industries can be found by clicking here.

David continued "as a result of the overwhelming response to this article we have released a series of NEW SFC Screening Kits which include all the BEST columns in the article:

• GreenSep DEAP for Alcohols
• GreenSep Ethyl Pyridine II for Acids
• GreenSep Nitro for Amides
• GreenSep Basic for Amines and with universal applicability for all compound groups.

all available in three different size configurations". Click here for ordering details.

In this issue of ESNotes we would also like to share with you some of the exciting recent product introductions and enhancements including some from past ES Notes:

• The new GreenSep Amino Phenyl SFC stationary phase which has proven superior to "older" normal phase materials,
• Chromegabond Ultra HPLC Columns a commercial equivalent to the Beckman Ultrasphere® columns.
• The first part of the tutorial a Basic SFC Primer outlining the essential elements of SFC including mobile phase characteristics and modifiers/additives along with column characteristics.

All designed to be technically informative and practically useful.

Basic SFC Primer Part I

In this two part series we provide a Basic SFC Primer for the chromatographer. Supercritical Fluid Chromatography (SFC) has been utilized in various forms in the last 50 years and improvements in instrumentation and column technology have led to the growth of the technique over the last decade. The first part of this series will review the mobile phase characteristics, mobile phase modifiers/additives and basic column characteristics. Part II will cover the role of the stationary phase, column selection and sample considerations.

GreenSep™ Amino Phenyl SFC Columns

GreenSep Amino Phenyl has proven superior to conventional stationary phases (such as diol, cyano etc...) in the areas of separation selectivity, peak shape and loading capacity. The linked application exhibits the superior peak shape performance and separation capacity obtainable with the GreenSep Amino Phenyl column with SFC. The application shows chemicals that are functionalized with amine groups and acidic groups and demonstrates the flexibility that GreenSep Amino Phenyl can deliver to the SFC chromatographer. GreenSep Amino Phenyl is the SFC column ideally suited for the retention and rapid separation of chemicals containing acidic groups.

Chromegabond Ultra™ HPLC Columns

Chromegabond Ultra™ - The Chromegabond Ultra line is an equivalent to the Beckman Ultrasphere® columns. The most popular material, Ultra C18 is available in 3μ and 5μ sizes with bulk and preparative material also available. Excellent efficiencies, peak shape and resolution are obtained for virtually all Ultrasphere® HPLC applications.
