| Notes | The particle size distribution of DiatoSorb material is more uniform than that of commercially available diatomaceous earth material. For this application, the pressure required to achieve a flow rate of 40 mL/min He (@ 100 °C) on a diatomaceous earth packed column is 50 psi, whereas it is only 33.7 psi on a DiatoSorb packed column. Furthermore, the narrower particle size distribution of the DiatoSorb material results in highly efficient columns. |
relativo alle ricerche nella libreria dei cromatogrammi
Consigli per la stampa! Per stampare cromatogrammi su tutta la pagina, cambiare le impostazioni di stampa nella finestra di stampa del vostro software PDF reader: 1)"adatta" o "adatta alla pagina", 2)"panorama" per cromatogrammi grandi o "ritratto" per cromatogrammi alti.
