“…Several automated chromatography separation systems have been developed to reduce the personnel workload. − In fact, automated methods have long been successfully established and adopted in fields of traditional stable isotope analysis. − In recent years, the development and adoption of similar methods for radiogenic and non-traditional stable isotopes have also been developed, − where the eluent is controlled by a peristaltic pump or syringe pump. Among these pump-based systems, the commercialized fully automated ion exchange chromatography system prepFAST-MC (ESI, Omaha, NE, USA) has received increasing interest.…”

A novel, simple, cost-effective, reliable, and practical automatic column chromatography separation device capable of simultaneously purifying samples for radiogenic and non-traditional stable isotope analysis has been developed. The device avoids the use of any pump and features eluent driving by the siphon effect (gravity) and quantitative control by infrared droplet counting. Several factors affecting the control of droplets were investigated, including types and concentrations of eluents and the height of the liquid level. Results showed that accurate dripping of the eluent could be readily achieved by controlling the number of droplets under selected conditions. The separation performance of the device was first demonstrated by the elution of Sr and Cd in synthetic matrix solutions. The recoveries of Sr and Cd samples were better than 87.6 and 95.0%, respectively, and the whole procedure blank was about 0.3 ng for Sr and 0.1 ng for Cd. Finally, the reliability of the device was further validated by the purification of Sr and Cd from different geological reference materials (NIST 2711a, Nod-A-1, BCR-2, and BHVO-2). The determined Cd and Sr isotope values agree well with their reference values within the uncertainty range. All these results clearly demonstrate the reliability and practicability of the proposed device, which provides a promising method for the automated purification of isotope samples.

“…Research has been directed towards miniaturization 16 and automation 19 in hopes of improving the overall efficiency of trace element analysis in actinide matrices while minimizing user interaction. Regarding automation, studies have explored uranium matrix removal 18–20 as well as U purification using UTEVA ion exchange resins, 21 but none have explored the Th and Bio-Rad AG MP-1 methodology. Previous studies have shown that efficient separation of thorium from various analytes has been achieved using both anion exchange and extraction chromatography techniques.…”

Presented here is a novel automated method for determining the trace element composition of bulk thorium by inductively coupled plasma–optical emission spectroscopy (ICP-OES). ICP-OES is a universal approach for measuring the trace elemental impurities present in actinide-rich materials; however, due to the emission rich spectrum of the actinide, a separation from the trace elements is warranted for spectrochemical analysis. Here, AG MP-1 ion exchange resin was utilized for retention of the Th matrix, while allowing the trace element impurities to be separated prior to subsequent analysis using ICP-OES. After demonstrating the separation on traditional gravity-driven columns, the methodology was transitioned to an automated platform for comparison. This automated platform utilizes syringe-driven sample and solvent flow and can collect the trace element and thorium fractions in separate locations. While reducing the sample size (500 µL, 1.5 mg of Th), maintaining the overall separation efficiency (recoveries >95%), and illustrating the sample throughput ability (n = 10+), this automated methodology could be readily adopted to nuclear facilities in which the determination of trace elemental impurities in Th samples is warranted.
