Capillary Electrophoresis for Nuclear Applications
A fast, versatile, automated solution for analysis of anions and cations in nuclear applications.
Anions and cations are routinely monitored in a variety of aqueous samples that are important to several industries, such as in the nuclear power plants. Although the most common methods for determining total concentrations of these ions is ion chromatography, more recently Capillary Electrophoresis (CE) has also been shown to be a viable option for the analysis of ions in solution at trace levels.
The technique of capillary electrophoresis (CE) appears to be a promising alternative to the conventional plant monitoring instrument currently employed by BWR operators because it offers much greater sensitivity to ionic contaminants (much lower LOD), a reduction in liquid radwaste generation, and less demand on the plant chemists’ time. By CE it has been possible to get limits of detection in the sub-ppb range, offering significant promise for direct, on-line chemistry monitoring of reactor coolant/ streams.
Single Source Solution for Nuclear Industry
Capillary Electrophoresis (CE) is an analytical technique alternative to ion chromatography that has been useful for direct detection of both anionic and cationic impurities in extremely pure water such as the condensate and feedwater of boiling water reactors (BWRs) in nuclear industry.
GPA100 CE and Its Benefits
Capillary Electrophoresis offers much greater sensitivity to ionic components (much lower LOD), minimum sample and buffer volumes and less demand on the chemists’ time.
The sensitivity of conventional CE technology has been improved through use of special chemical probes for use with indirect ultraviolet (UV) light detection.
The GPA100 Capillary Electrophoresis instrument is a bench-top prototype system that can be used easily by lab personnel providing continuous useful data with minimum use of lab personnel labor and it allows multiple accesses to the various probes, buffers, wash solutions, standards, etc.
Modular system fits easily into any lab environment.
All key components are visible and easily accessible for operation, maintenance and repair.
The following are the elution sequence and the observed limits of detection ug/kg (ppb) for a six anions standard solution:
Br - 2.0;
Cl - 0.05;
SO4 – 0.75;
NO3 - 1.0;
PO4 - 5.0;
F - 1.6

For CE analysis of cations the following electropherogram is
an example of the separation where the limits of detection for each of them are about 10 ug/kg (ppb):

These optimizations have been carried out for anions at the laboratories of Groton Biosystems, Inc., the developer and supplier of the CE hardware.
We are experts in this technology and we not only supply systems but we also provide:
Consumables for CE Analyses, Method Development Services, Hands-on and Webinar Workshops, Service Contracts for PrinCE, Crystal, and Thermo Systems, High Quality Kits for the Analysis of Metals, Phosphate, Organic Anions, Cations, etc.
