- octaaluminium(3+) octakis((2Z)-4-ethoxy-4-oxobut-2-en-2-olate) octakis(1-methoxypropan-2-olate) octakis(2-(dimethylamino)ethan-1-olate)
- Test material form:
- liquid
- Details on test material:
- purity not specified, batch 25/2/87R
Constituent 1
Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- The samples taken from the test media (approx. 100 ml) were treated as follows:
10 ml of a sample was led through an activated Sep C18 column followed by eluation with 1 ml methanol (Merck, lichrosolv), The 100 µl eluent was diluted with methanol and internal standard in such a way that the response of the gas chromatograph was comparable with that recorded for a calibration standard of concentrations approximately of 250 mg/L.
