Pharmeuropa is a free online EDQM
publication. Draft monographs are published in Pharmeuropa for public enquiry,
which lasts for three months.
Draft Monographs and General Texts for
Comment.
2.3.2 Identification of fatty oils by thin-layer
chromatography
Method A: chromatogram of hydrogenated
arachis oil added.
2.2.32 Loss on drying
Due to its toxicity, the replacement of
diphosphorus pentoxide with a molecular sieve is proposed. The introduction of a standardised amount of
desiccant to be used will also help to alleviate to a certain extent that
variability.
The conditions of ‘high vacuum’, which
were reported to be difficult to achieve with available instruments, are
proposed for deletion; this would trigger a revision of the concerned
monographs in due time. Additional
clarifications are proposed throughout the general chapter.
