Determination of low-aliphatic aldehydes indoors by micellar electrokinetic chromatography using sample dissolution manipulation for signal enhancement
(Wiley-Blackwell, 2003-02-01)
This work describes a novel approach for the analysis of selected aldehydes (formaldehyde, acetaldehyde, propionaldehyde, and acrolein) and acetone in environmental samples using micellar electrokinetic chromatography ...
Avaliação de contaminantes inorgânicos e orgânicos em álcool combustível utilizando eletroforese capilar
(2006-01-01)
This work reports the analysis of inorganic and organic contaminants in alcohol fuel samples using capillary electrophoresis. Chloride and sulfate were analyzed in nitrate/ monochloroacetic acid at 10 mmol L -1 concentration ...

Measurement of atmospheric formaldehyde using a drop collector and in-situ colorimetry
(Gordon Breach Sci Publ Ltd, 1997-01-01)
A sensitive and affordable approach is described for the in-situ measurement of ambient formaldehyde. Air is sampled around a 100 microliter aqueous drop containing 3-methyl-2-benzothiazoline hydrazone. After a desired ...

Gota suspensa para avaliação de aldeído total no ar interno e externo do ambiente
(Sociedade Brasileira de Química, 2001-08-01)
A sensitive and simple system was proposed for the in situ measurement of total aldehyde in outdoor or indoor ambient. The method is based on the use of a reagent drop as an useful interface to preconcentrate the sample ...
