The fundamental principles of ion-exchange solid-phase extraction

Three main points summarize the best ways to be successful in GC:capillary GC is clean GC; practice, practice, practice; and be a student of GC.

Part I of this series on practical perspectives of data integrity focuses on sample management, transport, and preparation.

HS-SPME-GC–MS is a valuable technique for identifying volatile organic compounds, additives, and degradation products in industrial rubber, car labeling reflection foil, and bone cement materials.

Ion chromatography (IC) is a form of liquid chromatography that is able to measure the concentrations (in parts per billion) of anions such as chloride, fluoride, nitrate, and sulfate, and cations such as ammonium, calcium, magnesium, and sodium.
