EXHIBITOR NAME ROOM # DESCRIPTION
2:00 p.m.
“New EPA Methods for Bromate and Perchlorate Using Two-Dimensional Matrix Elimination IC”
Abstract: Matrix elimination is a method of sample preparation that removes interfering matrix species
prior to analysis. The process of matrix elimination for environmental samples is especially
challenging due to the wide variety of matrices and analytes. For environmental contaminants
applicable to ion exchange separation, matrix elimination has evolved from offline, labor intensive,
sample preparation steps to automated on-line analysis, and finally two-dimensional applications that
not only remove matrix interferences, but provide improved selectivity and increased sensitivity. This
new, Matrix Elimination Ion Chromatography (MEIC) shows a four-fold increase in sensitivity for
bromate and perchlorate analysis. This technique has resulted in the creation of two new EPA
methods for drinking, waste-, and ground water analysis.
3:00 p.m.
“Biofuels Analysis: Meeting the Challenge of Quality Biodiesel and Bio-ethanol Manufacturing”
Abstract: One of the biggest challenges facing the biofuels industry is the development of robust
analytical methods for quality control of reaction processes and end products. This presentation will
cover the products and solutions that Dionex offers to support biofuels analysis at each stage of
production—from raw materials analysis to process monitoring and end product quality.
4:00 p.m.
“Automated Method Development with an HPLC System Optimized for Scouting of Columns, Eluents
and Other Method Parameters”
Abstract: In this session you will learn about a new integrated system that allows automatic and
intuitive scouting of columns, eluents, and other important method parameters like column
temperature. Up to two column selection valves in the column compartment provide high application
flexibility. Intelligent software makes parameter permutations easy, without requiring method changes.
Data mining tools help evaluating results and identifying optimal conditions.

10:00 a.m.
“Setting Meaningful Detection and Quantitation Limits”
Abstract: This session will cover concepts related to minimum limits for detection, quantitation, and
reporting, and show how sound statistical techniques for setting appropriate limits can be easily
implemented using Chromeleon® software. The Hubaux-Vos approach for setting detection limits will
be explained, and a Chromeleon template for quickly determining EPA’s LCMRL (Lowest
Concentration Minimum Reporting Level) will be shown.
11:00 a.m.
“Trace Analysis of Ions using AutoPrep”
Abstract: Trace analysis is one of the more challenging techniques facing chemists in ion
chromatography. Despite the ideal matrix, typically de-ionized ultra-pure water, there can be a
daunting host of obstacles when faced with the need to analyze at detection limits that are routinely in
the range of sub-ng/L. The name “AutoPrep” describes a series of automated steps used to prepare
samples on-line. The preparation process can include steps to perform calibration, matrix elimination,
concentration, or other techniques. AutoPrep processes samples using novel valve configurations and
timing to achieve sample handling without direct sample contact by the end user, or analyst. The goal
of AutoPrep is to mitigate the factors that contribute to contamination in Trace Analysis by isolating the
sample from the external environment.
12:00 p.m.
“New Solutions for Routine Water Analysis”
Abstract: This seminar will describe new solutions for routine monitoring of anions and cations in
drinking water using basic ion chromatography systems. These solutions include the latest RFIC-ER
technology for increased ease of use and consistent results. In addition, the determination of bromate
and disinfection byproducts using RFIC-EG and two-dimensional IC methods will be discussed.
1:00 p.m.
“ASE for the Determination of Total Lipids in Complex Foods”
Abstract: This presentation will focus on the use of ASE and the Dionium pathway for performing
solvent extraction of acid or alkaline pretreated sample matrices.
2:00 p.m.
“Addressing the New Era of Food Safety Concerns”
Abstract: Food safety is commanding increased public and policymaker attention, with emphasis on
imports. Dionex recognizes the importance of food safety and the health risks that are associated with
it. Dionex has developed solutions that address the public’s food safety concerns.
