After joining the faculty at Toyohashi University of Technology (TUT) in 1978, the author has found two areas in separation sciences where microcolumn liquid chromatography (micro-LC) can be beneficial. One is the hyphenated techniques between many spectroscopic methods such as mass (MS), infrared (FT-IR) and atomic emission (ICP), and micro-LC. The other one is rather difficult, but basic and ...

Additionally, MS/MS fragmentation used in combination with computational methods for predicting fragmentation patterns offers a robust alternative for the identification of molecules. Finally, the use of NMR via the hyphenated techniques HPLC-NMR or HPLCSPE-NMR offers a much more powerful tool for dereplication and is essential in some cases to undoubtedly establish the structure of a given com...

Different chromatographic and electrophoretic techniques commonly used in the instrumental inspection of herbal medicines (HM) are first comprehensively reviewed. Chemical fingerprints obtained by chromatographic and electrophoretic techniques, especially by hyphenated chromatographies, are strongly recommended for the purpose of quality control of herbal medicines, since they might represent a...

The complexity of selenium (Se) chemistry in the environment and in living organisms presents broad analytical challenges. The selective qualitative and quantitative determination of particular species of this element is vital in order to understand selenium's metabolism and significance in biology, toxicology, clinical chemistry and nutrition. This calls for state-of-the-art analytical techniq...

Understanding adolescents' use of ethnic labels is a key developmental issue, particularly given the practical significance of identity and self-definition in adolescents' lives. Ethnic labeling was examined among adolescents in the traditional immigrant receiving area of Los Angeles (Asian n = 258, Latino n = 279) and the non-traditional immigrant receiving area of North Carolina (Asian n = 16...

The current eye-movement study investigated whether a salient segmentation cue like the hyphen facilitates the identification of long and short compound words. The study was conducted in Finnish, where compound words exist in great abundance. The results showed that long hyphenated compounds (musiikki-ilta) are identified faster than concatenated ones (yllätystulos), but short hyphenated compou...

In this paper, the authors explore the hyphenated spelling variant on papers taken from the Business Source Complete (BSC) repository. This paper finds that the hyphenated spelling variant is popular with more recent authors and that in total, socio-technical article publishing has recently recovered from the relative decline of the 1980s and 1990s. Within the socio-technical area, the topics o...

The metabolic profiling of human amniotic fluid (HAF) is of potential interest for the diagnosis of disorders in the mother or the fetus. In order to build a comprehensive metabolite database for HAF, hyphenated NMR has been used, for the first time, for systematic HAF profiling. Experiments were carried out using reverse-phase (RP) and ion-exchange liquid chromatography (LC), in order to detec...
