This technical note from Phenomenex discusses the use of mobile phase pH to control analyte ionization states (pH-LC) in RP-HPLC as a highly effective way to change selectivity. The ionized species of an analyte is shown to have higher polarity (less hydrophobicity) than the neutral species, which results in a loss of expected retention for that analyte. With the use of mobile phase pH in conjunction with a pH-stable column, powerful selectivity manipulation can be achieved.

In the last few decades, the novel functions of polysaccharides have provided a major impetus for increasing scientific attention. Among the most promising aspects are their immunomodulatory and antitumor effects, thickening agents and stabilizer effects.

Q: We currently use a glass filtration setup attached to a pump using 0.45-?m membrane filters. The flask contains a magnetic stirrer. As the solution passes the membrane filter, gas bubbles appear on its surface. As soon as the solution has completely passed through the filter the vacuum pump is turned off and the solution is poured from this setup into another bottle and stoppered until use (up to 3?4 days time). The HPLC equipment has inline degassers that are routinely used. Besides filtering is this setup degassing? To effectively degas a solution should the solution remain under vacuum for a longer period than the time it takes to filter? Should we be using this setup to filter?degas HPLC-grade solvents or commercial mobile phases?
