Solvent

HPLC grade acetonitrile, methanol, water or mixtures of these for bio-molecules. DCM, DEE, THF for polymers.

Volume

0.5-1 µL

Concentration

<5000 Da, use 1-10 pmol µL^-1
>5000 Da, use 10-100 pmol µL^-1

Caution

Sensitivity and resolution are compromised by the presence of salts. Rigorous sample clean up improves analysis.
