Article Title: Simultaneous determination of various bioactive redox components in Shuang-Huang-Lian preparations using a novel three-channel isocratic elution liquid chromatography with electrochemical detection system.
Article Snippet: A novel three-channel isocratic elution high performance liquid chromatography with electrochemical detection (3LC-ECD) system was developed for the simultaneous determination of various bioactive redox components in Shuang–Huang–Lian (SHL) preparations.. This 3LC-ECD system consists of three isocratic elution flow ways, two switching valves, four columns, and three electrochemical detectors.. Through alternately rotating switching valves to change the elution flow way, six caffeoylquinic acids, four flavonoids, and one phenylethanoid glycoside compound were simultaneously determined within 70 min by the present 3LC-ECD method, in which three compounds of protocatechuic aldehyde, propyl gallate, lectrochemical detection affeoylquinic acids lavonoids henylethanoid glycosides and kaempferol were used as internal standards.

Article Title: Determination of Phenolic Compounds in Beverages by Three-Flow Channel Isocratic HPLC with Electrochemical Detections Using a Column-Switching Technique.
Article Snippet: This system consists of a degasser (DG-34, Flom, Tokyo, Japan), three types of mobile phases (MP1–3), three intelligent pumps (P1–3, AI-12, Flom), a manual injector (Inj., 7725i, Rheodyne, Cotati, CA, U.S.A.) with 5 μL of a sample loop, two switching valve units (SV1-2, 405, Flom), a pre-column (C0, InertSustain AQ-C18 (30 × 1.0 mm, 3 μm, GL Science, Tokyo, Japan)), three analytical columns (C1, Develosil XG-C30M-3 (250 × 1.0 mm, 3 μm, Nomura Chemical, Aichi, Japan); C2 and C3, Develosil XG-C30M-3 (150 × 1.0 mm, 3 μm)), three electrochemical detectors (D1–3, LC-4C, BAS, Tokyo, Japan), and a recorder (TR-V1000, Keyence, Osaka, Japan).

Article Title: Quantitative comparison of caffeoylquinic acids and flavonoids in Chrysanthemum morifolium flowers and their sulfur-fumigated products by three-channel liquid chromatography with electrochemical detection.
Article Snippet: Several equipment accessories were used to assemble the LC-3ECD system, including three pumps (AI-12, Flom, Tokyo, Japan), three electrochemical cells (Radial flow cell, BAS), three electrochemical detectors (LC-4C, BAS, Tokyo, Japan), two switching valves (Model 405, Flom, Tokyo, Japan), a vacuum degasser (DG-2080-53, Jasco, Tokyo, Japan), a sample injector fitted with a 5 μL injection loop (7725i, Rheodyne, Cotati, CA, U.S.A.), a recorder (TR-V1000, Keyence, Osaka, Japan), a column oven (CTO-10ASvp, Shimadzu, Kyoto, Japan), and four columns.

Article Title: Discrimination of magnoliae officinalis cortex based on the quantitative profiles of magnolosides by two-channel liquid chromatography with electrochemical detection.
Article Snippet: A two-channel liquid chromatography with electrochemical detection system (2LC-ECD) was newly designed for the simultaneous determination of magnolosides A, B, F, H, and L in the first channel and other magnolosides D and M in the second channel, respectively.. Peak heights had linear relationships to the magnoloside concentrations in a range of 0.02-16 mol/L for H, 0.01-12 mol/L for A, 0.02-12 mol/L for F and L, 0.01-8 mol/L for B, 0.002-6 mol/L for D, and 0.002-4 mol/L for M, respectively.. Seven magnolosides in magnoliae officinalis cortex (MOC) were determined by the 2LC-ECD, and the obtained quantitative profiles of magnolosides were applied to the discrimination between the MOC samples harvested from Hubei and Sichuan (called Chuan po) and from Zhejiang and Fujian (called Wen po).
