Development of Capillary Liquid Chromatography
Ishii’s group at Nagoya University started microcolumn liquid chromatography (μLC) more than 30 years ago [1]. His ideas have been realized in user−friendly μLC systems which are now commercially available from a number of manufacturers. In the meantime, injection valves with low dead volume, pumping systems working at low flow rates, high−resolution columns, and novel detection systems have be...
متن کاملVitamin U-bonded stationary phase in capillary ion chromatography.
A vitamin U-bonded stationary phase was prepared and the retention behavior of inorganic anions was examined using ion chromatography. Inorganic anions were retained on the vitamin U-bonded stationary phase under acidic as well as neutral eluent conditions in the ion-exchange mode. The elution order of the examined anions under neutral eluent conditions was nearly the same as that observed in...
متن کاملDevelopment and Validation of an Ion Chromatography Method for Quantification of Ammonium Ions in STEALTH® Liposomes
Ammonium sulfate is one of the subsidiary components in the stealth liposome structure. The ratio of ammonium ion bound to liposome sphere to ammonium ions outside the liposome plays an important role in drug delivery formulation; accordingly, in order to quantify the ammonium ion in the liposome structure, a rapid and sensitive method was validated using a conductivity detector. Through this m...
متن کاملComparison of ion mobility constants of selected drugs after capillary gas chromatography and capillary supercritical fluid chromatography.
Several test compounds were introduced into a unidirectional flow Ion mobillty spectrometer by both gas chromatography (GC) and supercritical fluld chromatography (SFC). The test samples were drugs from three general classes, opiates, benrodiazoplnones, and steroids. Drm spectra were collected for each compound by Fourier transform ion moblllty spectrometry. The drlft veioclty data for each com...
متن کاملRecent Development in Doppler Sonar Technology
There has been significant recent progress in the development of Doppler sonar systems for marine research. Major advances include the development of side-scan Doppler systems for surface wave, ship wake and Langmuir cell research, the development of coded pulses for improved sonar precision, and the development of phased array Doppler sonar for 3-D (x, y, t,) imaging of flow fields. Perhaps su...
