TL;DR: The results showed that dichloromethane and benzene are the preferred elution solvents for the adsorbed PAHs and recoveries become worse as the number of rings of PAH increased.

TL;DR: This paper presents an HPLC method for the determination of solanesol in the extracts of tobacco leaves that is fast, accurate and reproducible.

TL;DR: The method was applied to analyze amino acid composition of bovine serum albumin (BSA) and the results were in consistence with literature values and good results were obtained.

TL;DR: Different results were obtained by the two regeneration methods: the later is more effective than the former in reviving the purification characters of the chelating membrane adsorbent.

TL;DR: A reversed phase high performance liquid chromatographic (HPLC) method was established for the simultaneous separation and quantitative determination of the four drugs in serum and the eluted substances were detected at 210nm.

TL;DR: Toxic equivalence (TEQ) should be used as a kind of quality indicator for the studies of the photolysis of PCBs and was testified that the above retention index system was reliable during the identification of PCB congeners and would have wide applicability.

TL;DR: Both qualitative and quantitative differences in the volatile constituents among the three cultivars of hawthorn were not remarkable.

TL;DR: The plate model and diffusion model are equivalent to each other in describing chromatographic process although different mechanism is based on.

TL;DR: The combination of non-aqueous RP-HPLC with GC is a simple and rapid method for the analysis of oil TAG structure and is also very helpful for the identification of oil quality.
