"Flow Injection Procedure For The Determination Of Tertiary Amines In Water And Seawater Using Chemiluminescence Detection"
Analyst 1989 Volume 114, Issue 12 Pages 1659-1661
J. Steven Lancaster, Paul J. Worsfold and A. Lynes

Abstract: Sample was injected into a stream of borate buffer (pH 11.0), which merged first with 1 mM rhodamine B and then with 1.64 mM NaOCl (all at 1 mL min-1); detection of chemiluminescence was by a photomultiplier tube. The calibration graph for triethylamine was rectilinear for 0.2 mM in water and 0.1 mM in seawater. Coefficients of variation were generally 2% (n = 5). The method can also be used to determine trimethyl- and tripropyl-amine. Quenching of the chemiluminescence occurs in the presence of a 10-fold excess of diethylamine or ethylamine.

"Temporal And Spatial Analysis Of Electrogenerated Tris(2,2'-bipyridine)ruthenium(III) Chemiluminescent Reactions In Flowing Streams"
Anal. Chem. 1996 Volume 68, Issue 2 Pages 349-354

Abstract: Portions of 0.2 mM sodium oxalate (I), 0.2 mM proline (II) or 0.2 mM tripropylamine (III) and 1 mM tris(2,2'-bipyridine)ruthenium(II) [Ru(bpy3)2+] in 0.1 M potassium phosphate buffer (PPB) of pH 6 were mixed (1:1) and injected into a carrier stream of 0.1 M PPB of pH 6 (5.1-40.5 mm/s) and mixed in a 25 µL flow cell (construction described) containing a vitreous C electrode (VCE) at 1.25 V vs. Ag/AgCl. In stopped-flow studies, green Ru(bpy3)3+ was generated by bulk electrolysis of yellow 0.1 mM Ru(bpy3)2+ in 0.1 M Na2SO4 with a vitreous C sponge electrode at 1.05 V vs. Ag/AgCl. For FIA with CCD, equal volumes of analyte and 1 mM Ru(bpy3)2+ in 0.1 M PPB of pH 6 were pumped (0.04-8.88 mm/s) into the flow cell with VCE at 1.25 V vs. Ag/AgCl. 2 mM or 4 mM I in PPB of pH 6 was pumped (10.1 mm/s) directly into the cell, for continuous-flow studies with a VCE coated with Ru(bpy3)2+ immobilized in a Nafion film (Lee and Nieman, Ibid., 1995, 67, 1789) at 1.25 V vs. Ag/AgCl. A 100 µL sample of analyte was injected into the buffer flow (10.1 mm/s) for FIA. Maximum chemiluminescence emission was obtained at low linear velocities (LV) for I which reacted slowly and at increasingly higher LV for II and III respectively.

"Development Of A Silicon Photodiode, Electrogenerated Chemiluminescence, Flow-through Detector"
Anal. Proc. 1995 Volume 32, Issue 4 Pages 125-127
Andrew W. Knight, Gillian M. Greenway and E. David Chesmore

Abstract: A solid-state Si photodiode detector was developed and incorporated into a flow cell with electrodes for electrogenerated chemiluminescence (cross-sectional diagram given). The system was applied to the electrochemiluminescent reaction of tris (2,2'-bipyridyl)ruthenium(II) [Ru(bpy)32+] and tripropylamine. A single positive potential was applied to the working electrode to produce the Ru(bpy)33+; oxidation products of the amine then react with water to form highly reducing intermediates that can reduce the Ru(bpy)33+ complex back to Ru(bpy)32+ in an excited state which emits light. The optimum experimental conditions were: 1.2 mM Ru(bpy)32+ in 0.05 M phosphate buffer of pH 6.5 at a flow-rate of 2 ml/min and voltage pulses from 0-1.35 V (vs. Ag) over 5 s. Sample injection was performed by either pre-mixing samples of tripropylamine and Ru(bpy)32+ reagent followed by injection or by pumping both solutions directly and continuously into the detection cell; the latter method is preferred as the analysis time is shortened, there is no inline dispersion and signal intensity and reproducibility are improved. The calibration graph was linear over 3 decades with a detection limit of 140 ppb. RSD (n = 5) ranged from 0.5-2.4%.

"Spectrophotometric Detection For Flow Injection Analysis Of Tertiary Alkylamines In Terms Of The Intermolecular Charge-transfer Interaction With Iodine"
Bull. Chem. Soc. Jpn. 1991 Volume 64, Issue 8 Pages 2613-2615
Bunji Uno,Kiho Nakajima and Satoshi Kawai

Abstract: Sample of triethylamine (I), tripropylamine (II), or tributylamine (III) in a carrier stream of CH2Cl2 (1 mL min-1) was merged with a 1 mL min-1 stream of a 10 mM solution of I in CH2Cl2 (flow diagram given). The absorbance of the reaction mixture was measured at 290 nm. The detection limit was 1.36 ng for I, 1.63 ng for II and 2.63 ng for III and calibration graphs were rectilinear. The method should be suitable for use as a post-column detector in HPLC analysis.
