A novel flow injection‐chemiluminescence (FI–CL) approach is proposed for the assay of pioglitazone hydrochloride (PG‐HCl) based on its enhancing influence on the tris(2,2′‐bipyridyl)ruthenium(II)–silver(III) complex (Ru(bipy)32+‐DPA) CL system in sulfuric acid medium. The possible CL reaction mechanism is discussed with CL and ultraviolet (UV) spectra. The optimum experimental conditions were found as: Ru(bipy)32+, 5.0 × 10−5 M; sulfuric acid, 1.0 × 10−3 M; diperiodatoargentate(III) (DPA), 1.0 × 10−4 M; potassium hydroxide, 1.0 × 10−3 M; flow rate 4.0 ml min−1 for each flow stream and sample loop volume, 180 μl. The CL intensity of PG‐HCl was linear in the range of 1.0 × 10−3 to 5.0 mg L−1 (R2 = 0.9998, n = 10) with limit of detection [LOD, signal‐to‐noise ratio (S/N) = 3] of 2.2 × 10−4 mg L−1, limit of quantification (LOQ, S/N = 10) of 6.7 × 10−4 mg L−1, relative standard deviation (RSD) of 1.0 to 3.3% and sampling rate of 106 h−1. The methodology was satisfactorily used to quantify PG‐HCl in pharmaceutical tablets with recoveries ranging from 93.17 to 102.77 and RSD from 1.9 to 2.8%.

Electrogenerated chemiluminescence (ECL) is fundamentally dependent on the applied electrode potential, and measuring ECL intensity over a range of different potentials is commonly used to examine the underlying chemical reaction pathways responsible for the emission of light. Several research groups have now demonstrated that the applied potential can be exploited to selectively elicit ECL from: 1) multiple excited states within a single chemical species; 2) multiple emitters sharing a common co‐reactant; or 3) distinct ECL systems. This new generation of multiplexed ECL processes has been facilitated by the extensive development of novel electrochemiluminophores and instrumental approaches such as the near‐continuous collection of ECL spectra with CCD detectors during voltammetry or chronoamperometry experiments.

In this tutorial we describe the construction of chemiluminescence detectors for high performance liquid chromatography (HPLC), comprising the components required to deliver the chemiluminescence reagent, a coiled-tubing flow cell, photomultiplier tube and detector housing, and various options for data acquisition. We also discuss two state-of-the-art commercially available chemiluminescence detectors for HPLC and other flow analysis methodology.
