چکیده

The paper describes an integrated luminometer able to perform fluorescence (FL), room temperature phosphorescence (RTP) and chemiluminescence (CL) measurements on seawater samples. The technical details of the instrumentation are presented together with flow injection (FI) manifolds for the determination of cadmium and zinc (by FL), lead (RTP) and cobalt (CL). The analytical figures of merit are given for each manifold and results are presented for the determination of the four trace metals in seawater reference materials (NASS-5, SLEW-2) and Scheldt estuarine water samples.

Microplate-reader method for the rapid analysis of copper in natural waters with chemiluminescence detection

We have developed a method for the determination of copper in natural waters at nanomolar levels. The use of a microplate-reader minimizes sample processing time (~25 s per sample), reagent consumption (~120 μL per sample), and sample volume (~700 μL). Copper is detected by chemiluminescence. This technique is based on the formation of a complex between copper and 1,10-phenanthroline and the su...

Direct Chemiluminescence Determination of Oxymorphone Using Potassium Permanganate and Polyphosphoric Acid

Abstract A simple and sensitive chemiluminescence (CL) method was developed for direct quantification of oxymorphone, a µ opioid agonist that is approximately 10 times more potent than morphine. In this method potassium permanganate in polyphosphoric acid was used as CL reagent. Using this method, oxymorphone can be determined over the concentration ranges 13.5-337.8 ng mL-1 and 0.34-6.76...

Terbium Sensitized Chemiluminescence Method for the Determination of Rabeprazole -Application to Pharmaceutical Analysis and Dissolution Studies

A simple and sensitive chemiluminescence-based method was established for the determination of rabeprazole.The proposed method was based on the enhancing effect of rabeprazole on Ce(IV)-Na2SO3 -Tb(III) chemiluminescence reaction. A possible mechanism was discussed for chemiluminescence system by studying UV-Vis, fluorescence and chemiluminescence spectra. The effects of va...

6.02 Controls of Trace Metals in Seawater

Since the early 1970s, marine chemists have gained a first-order understanding of the concentrations, distributions, and chemical behaviors of trace metals in seawater. Important factors initiating this quantum leap in knowledge were major advances in modern analytical chemistry and instrumentation, along with the development and adoption of clean techniques. An instrumental development in the ...

Chemiluminescence Determination of Atropine using Luminol-Hemin-H2O2 System

A sensitive and fast chemiluminescence (CL) method has been described for the direct determination of atropine. The method is based on the quenching effect of atropine on the CL signals of the luminol– H2O2 reaction catalyzed by hemin in an alkaline medium. Hemin could strongly enhance the chemiluminescence of the luminol–H2O2 system. The luminophor of the luminol–H2O2–hemin CL system was ident...
