What is suppressor in ion chromatography?
A Suppressor is a device placed between the column and the detector, and acts to reduce the background conductivity of the eluent and enhance the conductivity of the analytes. For anion analysis, the suppressor is a high capacity cation exchange membrane or resin in the acid form.
Why suppressor is used in ion-exchange chromatography?
The suppressor removes sodium ions in the eluent and changes sodium carbonate to carbonic acid with lower conductivity, allowing the background levels to decrease. In addition, the suppressor changes sodium ions (cations), to hydrogen ions with higher conductivity.
What type of detector is used in ion chromatography?
Get high-performance conductivity detection for analytical and capillary ion chromatography separations. This detector is highly sensitive and specific to susceptible molecules, and is often used in tandem with conductivity detection as a general method that characterizes all ions in the sample.
What is non suppressed ion chromatography?
This year marks the 30th anniversary of the publication of Non-Suppressed Ion Chromatography, which is a method for the rapid separation of anions with on-line conductimetric detection. In this method, the separation column is connected directly to the conductimetric detector.
What is self regenerating suppressor?
• The Self-Regenerating Suppressor® (SRS® 300) is used for electrolytically regenerated suppression of IC applications requiring high capacity, low noise, and fast startup. SRS 300 suppressors are recommended for iso- cratic or gradient use with hydroxide eluents or methanesulfonic acid and sulfuric acid eluents.
What is an IC detector?
Conductivity IC detectors. Get high-performance conductivity detection for analytical and capillary ion chromatography separations.
What is IC in chromatography?
Ion chromatography (IC) is a sensitive separation technique that allows determination of multiple anions on the time scale of minutes.
What is Single Column Ion Chromatography?
Single Column Ion Chromatography (SCIC) combines low capacity-columns, low conductivity eluents and a detector with considerable electronic supression capability and enables quantitation of ions at the ppm level without the need of a suppressor column associated with other forms of Ion Chromatography.
