Any other information on results incl. tables
From the experimental Q(m) (N2) values and calculated surface areas, one may then calculate the values of Q(m) (EGME)eq equivalent to Q(m) (N2) for the surface areas of the samples. A comparison of the Q(m) (EGME)eq values with the apparent Q(m) (EGME)ap values from the isotherms defined the extend of EGME uptake by penetration (or site-specific interaction) for each of the solid samples.
Values of Q(m) (N2), Q(m) (EGME)eq, Q(m) (EGME)ap, and BET (N2) surface areas:
| Sample | Q(m) (N2) (mg/g) | BET (N2) area (m^2/g) | Q(m) (EGME)eq (mg/g) | Q(m) (EGME)ap (mg/g) | Q(m) (EGME)ap/Q(m) (EGME)eq |
| Ottawa sand | 0.032 | 0.11 | 0.042 | 0.035 | 0.83 |
| hematite | 0.14 | 0.50 | 0.18 | 0.18 | 1.00 |
| peat | 0.36 | 1.26 | 0.47 | - | - |

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
