Abstract
The chemiluminescent reactions of bis(2,4,6-trichlorophenyl)oxalate (TCPO) and bis(2-nitrophenyl)oxalate (2-NPO) with hydrogen peroxide in acetonitrile/water micellar systems (anionic, cationic, and non-ionic) and γ-cyclodextrin were studied in the presence of fluoranthene or 9,10-diphenylanthracene, imidazole, and two buffer solutions, HTRIS+/TRIS and H2PO4–/HPO42–. The relative chemiluminenscence (CL) intensity is higher in the presence of the cationic (DDAB, CTAC, DODAC, and OTAC), anionic (SDS), and non-ionic (Tween 80) surfactants. In the presence of some non-ionic surfactants (Brij 35, Brij 76, and Tween 20), the CL intensity was partially quenched compared with the reaction with no surfactant. The sensitivity for hydrogen peroxide determination in the range 0.01 × 10−4 to 1.0 × 10−4 mol L–1, considering the slope of the calibration curves (maximum peak height of CL vs. concentration), improved with the introduction of DDAH, CTAB, and SDS in HTRIS+/TRIS buffer.

Abstract
On-line detection of substances with an alcoholic or phenolic hydroxyl group using imidazole and peroxyoxalate chemiluminescence was investigated qualitatively using a flow-injection method. The substances tested included six polyphenols, five monophenols and six sugars. After incubation at 80 degrees C with an imidazole buffer (pH 9.5) the substances were detected by peroxyoxalate chemiluminescence. The polyphenols tested (e.g., pyrogallol, purpurogallin, and dopamine) showed the strongest light emission. The sugars with hydroxyl groups (e.g., fructose and lactose) and the monophenols (e.g., phenol, serotonin, and beta-estradiol) produced only a weak light emission. Imidazole served two roles, it catalysed the reaction with the hydroxyl compound and initiated peroxyoxalate chemiluminescence on-line. A novel reactor formed by packing glass beads into a flow cell (Teflon) of a chemiluminometer improved the sensitivity of light detection.

Abstract
A rotating flow mixing device having three directional inlets was developed for a high performance liquid chromatographic peroxyoxalate chemiluminescence detection system for the sensitive detection of fluorescent compounds separated with acidic mobile phases, such as those containing trifluoroacetic acid. The diameters of the three inlets were 0.3, 0.3 and 0.5 mm i.d., for an acidic column eluate, chemiluminogenic reagents (bis[4-nitro-2-(3,6,9-trioxadecyloxycarbonyl) phenyl] oxalate and hydrogen peroxide) and imidazole solution (for neutralization and as a catalyst), respectively. The three mixed solutions flowed out through an outlet (0.5 mm i.d.) at the centre of the top of the vessel. The reaction conditions to give the appropriate signal-to-noise ratio (S/N) were investigated using dipyridamole (an antiplatelet aggregation drug) as a typical fluorescent compound. The system was applied to the detection of dipyridamole and dansylated amino acids with a mobile phase containing trifluoroacetic acid. The detection limits for dipyridamole and each dansylated amino acid were 10 amol and sub-fmol (S/N = 2), respectively.
