Thioglykolová kyselina jako on-line předredukční činidlo pro speciační analýzu arsenu pomocí metody selektivního generování hydridů s kolekcí vymrazováním a atomovou absorpční spektrometrií
Musil, Stanislav ; Matoušek, Tomáš ; Rychlovský, P.
This work represents an improvement of current method of speciation analysis for determination of tri- and pentavalent inorganic, mono-, di-, and trimethylated arsenicals using atomic absorption spectrometry as a detector. Presented study shows that thioglycolic acid is suitable for an on-line pre-reduction which simplifies sample pretreatment and increases sample throughput.
Chemické generování těkavých forem stříbra jako metoda vnášení vzorku pro atomovou absorpční spektrometrii
Musil, Stanislav ; Kratzer, Jan ; Vobecký, Miloslav ; Rychlovský, P. ; Matoušek, Tomáš
A method of silver chemical vapour generation as a sample introduction technique for analytical atomic spectrometry is presented. Optimization of reaction and atomization parametrs was carried out and the efficiency of the chemical vapour generation was studied by means of radiotracer experiments.
