| Notes | The EPA Method 530 UCMR4 standard analyte concentrations vary to simplify preparing ICAL levels based on the minimum method reporting levels. The Method was developed on the Rtx-1701 column, but allows the use of any column with adequate selectivity. These target analytes are often included in EPA Method 8270, which uses the Rxi-5Sil MS column. |
Pour optimiser l'impression de votre chromatogramme, pensez à bien paramétrer l'imprimante !
Dans la fenêtre « Propriétés de l’imprimante » :
