Example text

Due to the sample state of matter, the sample preparation in ion chromatography can be divided into methods for [144] the following: 1. Liquid samples (filtration, dilution, pH change, standard addition, derivatization, liquid–liquid extraction, solid-phase extraction (SPE), distillation, micro-diffusion, membrane techniques) 2. Gaseous samples (absorption in solutions, absorption on solid carriers, sampling facilitated with membranes) 3. Solid samples (drying, homogenization, dissolution, extraction/leaching, digestion, combustion) Most water samples analyzed with ion chromatography do not have complex matrices (drinking water, precipitation water, surface and underground water).

The pressure increase can also be caused by using inappropriate organic solvent additions and analytical columns that are unsuitable for specific solvents. The lack of pressure or its fluctuation in the system is normally related to leakages and air-locking of the pump and/or eluent. The background conductivity problems usually concern the following: application of an unsuitable eluent, inappropriate suppressor work, CO2 absorption in the eluent, poor quality of water and reagents, and improper parameters of the detector work.

It combines elements from MS and ELSD technologies and offers better sensitivity, reproducibility, and dynamic response than ELSD. CAD and ELSD have been mainly coupled to RPLC and HILIC separation modes. 5. 2 ION CHROMATOGRAPHY APPLICATIONS Ion chromatography is one of the most important instrumental methods for determination of organic and inorganic ions in liquid, solid, and gaseous samples. It has evolved from a relatively simple method for determination of inorganic ions in water and wastewater at the milligram per liter concentration level into a sophisticated technique applied for separation and detection of organic and inorganic substances at the microgram per liter concentration level.
