Aren’t the salts used (Na, Mg) not mass spec compatible? Even with centrifuging, you can’t really ensure all salts were removed to an acceptable level.
after the d-SPE step, Ms. Joan pippetted the ACN layer direct to vial without filtering with 0.22um filter, I wonder that the final extract is really clear without solid particle that can harm the LC system?. Do we need to add filtering step on this experiment?
If filtration is used, one would need to be sure analytes are not lost during the filtration process. We do not filter any extract after dSPE, but we do use a guard column.
