How good is Thermo Fisher Fisher Ion Chromatography compared to photometry and atomic absorption method?

Thermo Fisher Ion Chromatography is a kind of liquid chromatography, so it is also known as ion chromatography or modern ion chromatography, which is different from the traditional ion exchange column chromatography is mainly resin with a high degree of crosslinking and low exchange capacity, the injection volume is very small, with a plunger pump to transport the eluent usually for online automatic continuous conductivity detection
of the eluent.

The analysis process for Thermo Fisher Scientific ion chromatography consists of five parts:
injection, separation, detection system and data system.

Applications of ion chromatography have penetrated into many fields
.

Applications range from the analysis of anions, cations and organic acids commonly found in water to the analysis of polar compounds, amino acids, sugars, heavy and transition metals and different oxidation states
.

As an effective trace analysis method, due to its simple, effective, high sensitivity and good reproduction, ion chromatography has replaced the traditional chemical analysis methods in many fields, such as trace Fe3+, Fe2+, Na+, K+ plasma analysis in steam cookers, and ion chromatography has been widely used
.

At the same time, it can also analyze chromium, silica, some heavy metals, and organic acids in different valence states
.

The residual concentrations of the coagulants Al and Fe, commonly used in water treatment, can also be accurately determined
.

Ion chromatography has also been widely used
in environmental, food, sanitation, petroleum development, petrochemical, high-purity water and hydrological strata.

After years of application and development, ion chromatography has gradually been accepted by the field of analysis at home and abroad, and has been determined by some internationally influential institutions as a standard analytical method or recommended method, becoming a promising analytical tool
.

Multiple ionic compounds can be analyzed simultaneously: Compared with photometry and atomic absorption methods, the main advantage of ICs is that they can detect multiple components in a sample at the same time, and all information about
anion, cation, and sample composition can be obtained in a short time.
