北京赛车pk10保本 www.jlu02.cn The Chromatographic Columns online database is a compilation of the chromatographic columns used to validate the chromatographic procedures in USP–NF, Pharmacopeial Forum, Revision Bulletins, and Interim Revision Announcements. It provides a cumulative listing of columns referenced in gas and liquid chromatographic methods related to revisions made to USP–NF since January 1980.
Chromatographic Columns Contents
Chromatographic Columns provides the following column data:
- Issue of PF in which a column was first referenced
- Corresponding packing, GC phase, or support (L, G, or S) designations
- Type of test employing the chromatographic method
- Alternative columns, when this information is available
- Brand names
How Chromatographic Columns Assists the User
- Save valuable time spent searching for the right columns to use in testing
- Track columns used in methods that have progressed from "revision" to "official" status
- Find brand names and manufacturers
- Locate alternative columns that may be used
The designation for a new column will receive a number ONLY when the text referring to this column becomes official, whether in a Supplement, in the next USP–NF, or in a Revision Bulletin or Interim Revision Announcement. During the proposal period in Pharmacopeial Forum, the new chromatographic column will be identified in the database by “L##,” “G##,” or “S##” followed by the monograph title and the column brand name in parentheses. No numbers will be assigned to the column designations during the proposal period. See the example below.
L## (Lanatoprost, Chiracel OD-R)─Cellulose tris(3,5-dimethylphenylcarbamate) coated on 10-μm silica gel particles.
In the actual text of the monograph or General Chapter that requires the new column, that column will be designated as “L##,” “G##,” or “S##” and will appear with the reference "(see Reagents, Indicators, and Solutions, Chromatographic Columns)
