What is the principle behind the actual operation of a phosphate analyzer?

Thread Content

The phosphate analyzer is an intelligent instrument featuring a user-friendly design and graphical menus, making it easy to operate. It offers options in both Chinese and English. Equipped with a monochromatic cold light source, it provides accurate and reliable measurements. It can be used for the measurement and storage of solutions in laboratories across industries such as power generation, chemicals, metallurgy, environmental protection, pharmaceuticals, biochemistry, food processing, and tap water treatment. Principle of the phosphate analyzer method: Ions have different distribution coefficients between the stationary phase and the mobile phase. When the mobile phase carries the sample into the separation column, the various ions in the sample are separated due to their differing relative affinities for the ion exchange resin, and then they proceed to the suppressor. The function of the suppressor is primarily to reduce the background conductivity of the eluate, increase the conductivity response of the ions being measured, and remove cations from the sample. The solution then flows through a conductivity cell, where it is detected by a conductivity detector; this allows for the creation of chromatograms for each ion. The retention time is used for qualitative identification, while the peak height or peak area is used for quantitative determination of the ion concentration.
