Water and chemical reagents used to prepare eluents and standard and regeneration solutions should be as pure as possible. Modern ion chromatographs contain in-built filtration systems. However, preliminary sample filtration is recommended to extend 36 PRINCIPLES AND APPLICATIONS OF ION CHROMATOGRAPHY the analytical column durability. 45 μm. Such particles can cause the back pressure increase in the analytical column and change the column characteristics. Water for the eluent preparation should be degassed, which prevents the baseline deformation and unstable system work.
When the sample is classified due to the accreditation process), it is recommended to perform a preliminary analysis with simpler methods, such as test strips. Measurements of the sample electric conductivity and pH provide preliminary information on the sample ion composition. Knowing such data prevents accidental introduction of large ion amounts into the analytical column and its overloading, which leads to the irreversible changes in the column characteristics. The selection of proper separation conditions (stationary-phase type; eluent type, concentration, and flow rate; suppression and detection types) depends on many factors, such as types of the determined ions, their stability and concentrations, and the sample pH.
