Microwave Digestion–Inductively Coupled Plasma Atomic Emission Spectrometric Determination of Boron in Raw Noodles

Autor: Jurgen L Kacprzak, John Ziaziaris

Publikováno v: Journal of AOAC INTERNATIONAL. 78:874-877

Samples of raw noodles in a mixture of nitric acid and hydrogen peroxide were microwave digested in sealed tetrafluoromethaxil (PTFE TFM) vessels. The digests were diluted to volume with distilled water and quantitated by inductively coupled plasma a

Determination of Methyl Mercury in Fish by Flameless Atomic Absorption Spectroscopy and Comparison with an Acid Digestion Method for Total Mercury

Autor: Jurgen L Kacprzak, Ramon Chvojka

Publikováno v: Journal of AOAC INTERNATIONAL. 59:153-157

A method for the concurrent determination of methyl mercury and inorganic mercury by flameless atomic absorption spectroscopy (AAS) is described. Fifty-seven samples of juvenile black marlin fish were analyzed for inorganic and methyl mercury, and to

Determination of o-Toluenesulfonamide in Artificial Sweeteners Containing Saccharin

Autor: Jurgen L Kacprzak

Publikováno v: Journal of AOAC INTERNATIONAL. 61:1528-1532

A gas-liquid chromatographic (GLC) procedure with p-toluenesulfonamide (p-TS) as an internal standard is used to determine o-toluenesulfonamide (o-TS), a major impurity in artificial sweetening substances containing saccharin. Although p-TS can itsel

Atomic Absorption Spectroscopic Determination of Dimethylpolysiloxane in Juices and Beer

Autor: Jurgen L Kacprzak

Publikováno v: Journal of AOAC INTERNATIONAL. 65:148-150

A method is described for determining dimethylpolysiloxane (DMPS), an antifoaming agent, in juices and beer. The method involves adsorbing the beverage onto Florisil (an activated porous magnesium silicate), drying, and Soxhlet extraction with chloro

Use of Background Correction to Improve the Accuracy of the Selective Reduction Method for Determining Methyl Mercury in Fish

Autor: Jurgen L Kacprzak, Ramon Chvojka

Publikováno v: Journal of AOAC INTERNATIONAL. 62:1179-1181

Background correction is used with a previously published flameless atomic absorption method for the concurrent determination of inorganic and methyl mercury. The use of background correction simplifies the procedure, but, more importantly, eliminate
