Vial Type |
2ml glass vial (Microtitre plates are an option - please contact the MS lab for details) |
Lid |
Snap-cap with teflon disk |
Solvent |
HPLC grade acetonitrile, methanol, water or mixtures of these |
Volume |
>200 µL, if less then use vial inserts Concentration |
Concentration (FIA) |
For FIA of molecules <2000 Da, use 1µg mL-1
For FIA of molecules >2000 Da, use 10µg mL-1 |
Concentration (HPLC) |
For HPLC of molecules <2000 Da, use 30µg mL-1
For HPLC of molecules >2000 Da, use100µg mL-1 |
Caution |
You must not use THF or DMF as solvent. API is severely compromised by the presence of involatile buffers and involatile salts. These must be removed from the sample or substituted by a volatile option, e.g. ammonium acetate. |
