| + | 70 | The tool assumes complete dissolution, an accurate label mass, an accurately measured diluent volume, and a syringe manufactured to its nominal scale. Each of those is an approximation: | |
| + | 71 | ||
| + | 72 | * incomplete dissolution leaves a concentration lower than calculated and a suspension of unknown uniformity; | |
| + | 73 | * diluent volume drawn on the same syringe used for dosing carries that syringe's own error; | |
| + | 74 | * syringe volume tolerance under ISO 7886 is a few percent of nominal capacity, which at the bottom of the barrel is a large fraction of a small dose;{{r|iso7886}} | |
| + | 75 | * [[Peptide aggregation|aggregated]] or partly degraded material has a peptide content lower than the certificate reports, and no arithmetic detects that. | |
