A new impurity was detected during high performance liquid chromatographic (HPLC) analysis of eslicarbazepine acetate active pharmaceutical ingredient. The structure of unknown impurity was postulated based on liquid chromatography mass spectrometry using electrospray ionization and ion trap analyzer (LC/ESI-IT/MS) analysis. Proposed structure of impurity was unambiguously confirmed by synthesi...

The impurity ion temperature evolution has been measured during three types of impulsive reconnection events in the Madison Symmetric Torus reversed field pinch. During an edge reconnection event, the drop in stored magnetic energy is small and ion heating is observed to be limited to the outer half of the plasma. Conversely, during a global reconnection event the drop in stored magnetic energy...

As a participating national lab in the inter-institutional effort to resolve performance issues of the non-elutable ion exchange technology for Cs extraction, we have carried out a series of characterization studies of UOP IONSIV IE-911 and its component parts. IE-911 is a bound form (zirconium hydroxide-binder) of crystalline silicotitanate (CST) ion exchanger. The crystalline silicotitanate r...

New Grad's-Zhdanov module is implemented in the SOLPS-ITER code and applied to ITER impurity transport simulations. Significant difference appears helium due improved parallel kinetic coefficients. As a result 30\% decrease of separatrix-averaged relative concentration observed for constant source pumping speed. Change behaviour discussed. For neon changes are less pronounced. first time ion di...

We have compared the time integrated photoluminescence ~PL! and the time resolved PL of several lattice matched InGaAs/InP quantum wells intermixed either by ion implantation or an impurity-free method. We have found that the carrier capture rates into quantum wells and carrier relaxation from the wells depend on the type of intermixing used. Our results indicate that the carrier lifetimes are ...

The present paper describes the reverse phasehigh performance liquid chromatographic method and was validated as per ICH guidelines for the determination of related substances in Cabazitaxel. RP-Liquid chromatography technique was performed with pH 3.0 phosphate buffer and acetonitrile as mobile phase at a flow rate of 0.8 mL/min. on Waters 2489 UV 2695 pump, Waters 2998 PDA 2695 pump Software ...

BACKGROUND The separation performance of seven polymer membranes for the nanofiltration of sodium lactate in fermentation broth was investigated. Each module was introduced into the test stand, and the system curve was obtained by recording the permeate flow velocity at different pump head levels. Performance benchmarks were good permeate quality, as determined by high permeate flow velocity, h...
