Our latest analytical tool is a Dionex Ion chromotograph (IC) which can analyze
cations, anions, sugars, saccarides and amino acids.
Ion chromotagraphy is often the technoque used for separating and quantifying
many types of ionic materials.

The Future of Ion Chromatography
With the introduction of Reagent-Free IC (RFIC), Dionex has simplified ion
chromatography while simultaneously increasing the power and reproducibility of ion
analysis. RFIC redefines the way ion chromatography is performed Advantages of
RFIC
Eliminate the time and errors associated with manual eluent preparation
Save time, labor, and operating costs
Improve reproducibility, day to day, week to week, lab to lab
Easy to use
Use only DI water!
In addition to saving time, labor, and operating costs, RFIC eliminates errors
associated with manual eluent preparation. This effectively improves method
reproducibility, day to day, week to week, lab to lab. With manual eluent preparation,
laboratories face more frequent method verification and troubleshooting because
different employees can make inadvertent variations in the preparation of eluents
and regenerants.RFIC not only takes the manual labor out of ion chromatography, it
is also easy to learn and easy to use. And, by running an IC system that pumps only
DI water, you increase the lifetime of pump seals and pistons. Technical
improvements provided by RFIC will improve the productivity of your laboratory in
other ways. While carbonate based eluents have been the basic eluent used for
anion analysis in IC for many years, Dionex RFIC, enables you to take full advantage
of the powerful tool of hydroxide-based eluents. Hydroxide eluents have higher
sensitivity and a broader linear response range for analyte conductivity. Hydroxide
based eluents make IC separations possible and now RFIC makes gradient IC
separations easy, routine, and reliable.
How Can RFIC Work For You?
RFIC combines automated eluent generation and self-regenerating suppression to
empower laboratories like never before. You no longer need to spend time preparing
eluents and regenerants. All that is required is a clean source of deionized water.
The Dionex IC system takes care of the rest. With RFIC, the ion chromatograph
electrolytically creates the required eluents and regenerants used for IC applications.
In addition to saving time, labor, and operating costs, RFIC eliminates errors
associated with manual eluent preparation. This effectively improves method
reproducibility, day to day, week to week, lab to lab.
Anion Applications
The IonPac® AS18 is a hydroxide-selective anion-exchange column that extends
Reagent-Free IC to routine anion determinations. The AS18 is designed for the fast
separation of common inorganic and low M.W. anions, including fluoride, acetate,
chloride, nitrite, bromide, nitrate, carbonate, sulfate, and phosphate. This column is
designed to meet the requirements for U.S. Environmental Protection Agency (EPA)
Method 300.0 Part A and Method 300.1 Part A. In fact, the EPA's Statistics and
Analytical Support Branch and the Office of Ground Water and Drinking Water's
Technical Support Center have recently concluded that the use of hydroxide eluents
falls within the method flexibility allowed in EPA Methods 300.0 and 300.1 for
determining inorganic anions. These methods are critical for compliance monitoring
under the Clean Water Act and Safe Drinking Water Act. Now it has never been
easier to set up and run compliance monitoring under the Clean Water Act and Safe
Drinking Water Act.
Cation Applications
Cation-exchange IC methods are similarly streamlined using RFIC with cation
exchange columns. The MSA eluent used with the IonPac CS16 column is easy to
program into the application method and allows isocratic separation of Group I and
Group II cations and ammonium.
Analyzing Trace Anions and Cations
Eluent generation makes trace level analysis of anions and cations routine. The
ultra-pure hydroxide produced by the EGC-KOH cartridge results in a low, stable
baseline which makes integration easier. Using the eluent generator with the CR-TC
Trap columns minimizes baseline shift during the step changes or gradients. For
cation determinations the EGC-MSA cartridge delivers ultra-pure MSA for a low,
stable baseline and reproducible retention times.
