Using the desalting tube "Solnac Tube" for LC/MS! DBA was removed online.
When analyzing highly polar acidic compounds using reversed-phase partition chromatography, adding basic ionic species to the eluent can enhance retention by forming neutral ion pairs through ionic bonding. In this case, nicotine acid and uracil acid were used as samples, and DBA in the sample solution was removed using a Sornak tube to conduct positive ion measurements. As a result, it was confirmed that Sornak is effective for LC/MS under mobile phase conditions containing ion pair reagents.
