Application of chemometric methods in environmental research.
PublikacjaW badaniach analitycznych zastosowanie nowoczesnych technik pomiarowych, połączone ze skróceniem czasu analiz, prowadzi do uzyskiwania obszernych zbiorów danych w stosunkowo krótkim czasie. Zastosowanie specjalnych technik obróbki zbiorów wyników pomiarowych sprawia, że możliwe jest ''wydobycie'' dodatkowych informacji z posiadanych danych. Idealnym narzędziem do tego typu zabiegów może być chemometria. W opracowaniu omówiono teorię...
