Low noise, low drift and wide dynamic range assure proven performance of the Shimadzu VP series HPLC. Data acquired by the CDD-10Avp is transferred to the SCL system controller via an optical fiber interface and are digitally processed by workstation. By adding the optional cell (dual kit NS), a low-cost and compact non-suppressor type dual ion chromatograph, which detects anions and cations simultaneously, can be made.
Built-in validation support functions help you comply with GLP/GMP regulations. A record of each module's operation is preserved and can be reviewed on-screen or printed. Calibration/validation of the conductivity cell is also incorporated.
LC-VP 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 ppb of F- can be analyzed without any preconcentration procedures.
The CDD-1OAvp is a conductivity detector applicable to ion chromatograph or organic acid analysis HPLC systems. The CDD-1OAvp has common features of the Shimadzu VP series HPLC modules, such as VP key for validation, and an optical communication interface.
Ion Chromatograph Dual Flow Analysis System
This system permits the analysis of both cations and anions from a single sample vial, efficiently measuring the ion balance. With Shimadzu's unique high performance column, and large volume sample injection, the quantitation of F- at levels of less than I 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 (Japanese Patent No. 2017498) 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.
