Unbenanntes Dokument
We need the following sample amounts plus some additional amount for sample handling.
| AAA Enantiomerlabeling |
At least 3mg, better 5mg |
|
without determination of blind values |
At least 1mg, better 3mg |
|
other amino acids |
At least 2mg, better 5mg |
|
AcOH / TFA – content |
At least 3mg, better 5mg |
|
Enantiomeric purity of amino acid derivatives |
At least 2mg, better 5mg |
|
Enantiomeric purity of peptides (GC-MS) |
At least 1mg, better 5mg |
|
Residuals of solvents |
At least 3mg, better 5mg |
|

For analyses in duplicate the required sample amount is double. |

The amount needed for sample handling depends on the physical properties. A freeze dried product needs nearly no additional amount whereas an oily product some 10mg’s.
These amounts are necessary to obtain the required accuracy of the weighing process (minimum weight in accordance to USP) and the required LOQ’s.
Please ask if these sample amounts are not available.
