A suppressor for ion chromatography is a crucial device utilized in ion chromatography to eliminate background noise-causing cations or anions from the eluent.
In ion chromatography, especially in conductivity detection methods, two main techniques prevail: non-suppressed and suppressed. By employing a suppressor, counter ions present in the mobile phase can be effectively removed, thereby diminishing the background concentration at the detector and enhancing the conductivity of the target ions through ion exchange. Consequently, a suppressor in ion chromatography significantly bolsters detection sensitivity, particularly in the analysis of anions.
Suppressors find indispensable utility in suppressed ion chromatography to eradicate background ions in the eluent. Ion chromatography operates by leveraging ionic interactions, enabling the measurement of inorganic anions and cations, alongside certain organic acids and amines. Detectable ions encompass inorganic anions such as NO2-, NO3-, SO42-, PO43-, and halide ions, as well as alkali metal cations (e.g., Li+, Na+, K+) and alkaline earth metal cations (e.g., Mg2+, Ca2+, Ba2+). Amines like methylamine, dimethylamine, ethylamine, and ethanolamine can also be detected using the same apparatus employed for inorganic cations.
Diverse applications of ion chromatography include:
Suppressors for ion chromatography harness ion exchange membranes or ion exchange materials (columnar, gel, fiber, etc.) to execute ion exchange. While certain ion exchange materials, such as gels, are discarded after single use, membrane dialysis types can be regenerated repeatedly by regenerating the ion exchange membrane while exchanging ions in the sample/eluent. Typically, they are interconnected between the column and the conductivity detector. Cation suppressors alleviate noise by substituting cations for hydrogen ions (H+), while anion suppressors perform the same by swapping anions for hydroxide ions (OH-).
Regeneration techniques for ion exchange membranes encompass chemical regeneration (utilizing sulfuric acid solution) and electrical regeneration (administering hydrogen ions produced by water electrolysis, etc.). Throughout the regeneration process, the system continuously furnishes hydrogen ions while exchanging ions in the sample/eluent to eliminate counter ions.
Suppressors for ion chromatography are primarily categorized into two types: cation (for positive ions) suppressors and anion (for negative ions) suppressors. As aforementioned, ion exchange within the suppressor can be achieved via ion exchange membrane technology or gel technology with hydrogen-type cation exchange resins.
Within ion exchange membrane suppressors, chemical regeneration variants necessitate a regenerant flow, whereas electrical regeneration suppressors can autonomously regenerate through the collaborative action of an electric field and ion exchange membrane. Moreover, compact models tailored for microbore and low-flow columns are available. Opting for the suitable suppressor hinges upon the specific application at hand.
