Key result

Type:

relative density

Density:

1.753 other: dimensionless

Temp.:

21.2 °C

Remarks on result:

other: Mean value of two assays (assay No.1: 1.767 at 20.9°C, assay No.2: 1.739 at 21.4°C)

Two independent measurements at 20.9°C (assay No. 1) and 21.4°C (assay No. 2) were done (each in triplicate) resulting in relative densities of 1.767 ± 0.001 and 1.739 ± 0.001, respectively. The mean relative density was thus 1.753 ± 0.015 at 21.2°C.

The measurements are described in the table in the next section.

Conclusions:

The relative density of tris[oxalato(2-)]digadolinium was determined according to EU A.3 method and OECD test guideline 109 in compliance with GLP using a gas comparison pycnometer. The relative density of the test item was determined to be 1.753 ± 0.015 at 21.2°C.

Description of key information

The relative density of gadolinium oxalate was determined in a GLP study (Klimisch 1, Demangel, 2016) performed according to the EU A.3 method and OECD test guideline 109 using a gas comparison pycnometer. The relative density of the test item was determined to be 1.753 ± 0.015 at 21.2°C.

This study was assigned as key study.
