Ion chromatograph system with CDD-10AVP

A highly versatile non-suppressed system

There are no restrictions when choosing mobile phase conditions, no worrying about competing ions or pH. Selection and adjustment of conditions can be made on a sample or analyte basis. The high degree of versatility of this non-suppressed system allows the analysis of various ions without peak broadening outside the column.

High performance demonstrated in every module

Every module of the Shimadzu LC-VP series has been designed to exacting standards to provide an optimum HPLC system. This makes high sensitivity analysis possible even with a non-suppressed system. As little as 1 ppb of F-can be analyzed without any preconcentration procedures.

Ion Chromatograph Dual Flow Analysis System

This system permits the analysis of both cations and anionsfrom a single sample vial, efficiently measuring the ion balance. With Shimadzu's unique high performance column, the Shim-pack IC-A3, and large volume sample injection, the quantitation of F- at levels of less than 1 ppb is possible. The simultaneous quantitation of monovalent and divalent cations at ppb levels is also possible with Shim-pack IC-C3 columns. The non-suppressed system provides a linear calibration curve even at low concentrations, as well as extremely good reproducibility of quantitation results.

Organic Acid Analysis System

Shimadzu's unique post-column pH-buffered electroconductivity method is ideal for the selective and highly sensitive detection of organic acids. Compared to conventional methods, such as the UV short wavelength method or a simple conductivity method, this system improves quantitation reliability. Compared to the post-column VIS absorption detection methods using pH indicators, this system has higher sensitivity, better linearity, and is easier to use. Complex samples (which usually require troublesome pretreatment) can be analyzed after simple pretreatment techniques such as dilution and filtration.
