Separation of selenium analogues of sulphur-containing amino acids by high-performance liquid chromatography and high-resolution gas chromatography
Autor: Hugo A.H. Billiet, Jaroslav Janák, Johannes Frank, Petr Hušek, Karel Ch. A. M. Luyben
Publikováno v: Journal of Chromatography A. 677:192-196
The historically conditioned adaptation of living organisms to chemically corresponding elements is influenced in nature by anthropogenic activities in many regions, the selenium-sulphur pair being one example of such a case. The separation of seleno

Capillary gas chromatography of C5C13 branched alkynes on squalane and liquid crystal stationary phases
Autor: Jaroslav Janák, Ladislav Soják, Ivan Ostrovský, Jacques R. Chértien, Pavel Farkaš
Publikováno v: Journal of Chromatography A. 557:241-253
The retention behaviour of 49 C5C13 branched alkynes, including all 36 methyl- and dimethylalkynes up to C8, were studied by capillary gas chromatography on squalane and 4-n-pentylacetophenone-O-(4-n-pentyloxybenzoyl)oxime liquid crystal as statio

A monitor for atmospheric sulphur dioxide, based on enrichment of SO2 by a polydispersive water aerosol
Autor: Jaroslav Janák, Zbyněk Večeřa
Publikováno v: Mikrochimica Acta. 102:29-34
A monitor for continuous analysis of sulphur dioxide in the atmosphere at the ppb v/v level (1 ppb v/v = 2.62 μg/m3 SO2) is described. The apparatus operates on the principle of equilibrium accumulation of sulphur dioxide from the air by a polydispe
