Trends in solventless sample preparation techniques for environmental analysis
PublicationPraca przedstawia najnowsze tendencje w metodach przygotowania próbek do analizy środowiskowej. Najpierw przedstawiono klasyfikację tzw. bezrozpuszczalnikowych technik przygotowania próbek. Następnie, szczegółowo przedstawiono trzy techniki, traktowane priorytetowo, a mianowicie: mikroekstrakcję do fazy stacjonarnej (SPME), ekstrakcję do pojedynczej kropli (SPME)i analizę fazy nadpowierzchniowej (HS), w odniesieniu do ich użyteczności...

Detection and time/frequency analysis of electric fields in the ground
PublicationThis paper sets out to detect and characterize electric fields in the ground (such as stray current fields) using a tandem time/frequency method of signal analysis. Results were obtained from investigations performed in the presence of a generated electric field with controlled variable characteristics, and in the presence of an electric field generated by a tramline. The analysis of measurement registers was performed using Short‐Time...
