i am writing to ask if someone can tell me which salts can be used in GPC-MS technique, for improving separation and ionization of compounds?
Thank you in advance for answers.
Best Regards,

Since GPC/SEC separations are based solely (or should be) on molecular size (correlates to MW, roughly) why do you think that addition of a salt would help the separation ??
