The methods are based on solid-phase extraction (SPE; disk or cartridge) followed by liquid or gas chromatography-mass spectrometry detection (tandem mass spectrometry or high resolution mass spectrometry). Depending on the sample preparation chosen, the sample preparation can be applicable to the analysis of selected estrogens in drinking water, groundwat ...Wed, 01 Apr 2026 00:00:00 +0200https://www.tzb-info.cz/normy/csn-en-iso-13646-2026-04 https://www.tzb-info.cz/normy/csn-en-iso-17829-2026-04Wed, 01 Apr 2026 00:00:00 +0200https://www.tzb-info.cz/normy/csn-en-iso-17829-2026-04 https://www.tzb-info.cz/normy/csn-en-iso-18708-2026-04Wed, 01 Apr 2026 00:00:00 +0200https://www.tzb-info.cz/normy/csn-en-iso-18708-2026-04
