Shimadzu CDD-10AVP Conductivity LC Detector

Shimadzu CDD-10AVP Conductivity LC Detector

Handles a Wide Variety of Analysis Options

The CDD-10AVP conductivity detector achieves an even higher level of sensitivity and makes it possible to perform a wide variety of analysis scenarios with a single unit. An option card enables the simultaneous 2-channel measurement of anions and cations, and a suppressor option allows expansion to a suppressor system for ultra-high sensitivity work. Organic acids can be analyzed using Shimadzu's unique post-column pH-buffered electroconductivity method.

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.

Perform Analysis with Highest Sensitivity:

The sensitivity of detectors that monitor weak electrical signals from analytes is affected by the inherent electrical noise of the detector itself. With the CDD-10AVP, electronic parts with low electrical noise are used, and the layout of the electronic components has been optimized in order to reduce noise levels, thereby attaining an extremely high level of sensitivity. Combining the CDD-10AVP with a suppressor unit makes it possible to perform ultra-high sensitivity ion analysis Reproducibility in Anion Analysis on the order of 0.25 μg/ L (detection limit: S/N=3) for Cl-.

Applicable to Both Suppressor and Non-Suppressor Systems (available in limited regions) :

When used with a CTO-20AC, expansion to a full suppressor system can be realized by adding the suppressor option. Suppressor functions can be disabled when necessary, making it possible to switch between anion analysis using a suppressor system and cation analysis using a non-suppressed system. In addition to a single flow-line system, expansion to a dual flow-line system is also possible, allowing the creation of a variety of system configurations. For example, simultaneous analysis of anions and cations using a combination of suppressed and non-suppressed detection is possible.

High-Sensitivity Analysis of Organic Acids :

Shimadzu's post-column pH-buffered electroconductivity method (Patent No. 2017498) enables selective, high-sensitivity analysis of organic acids. Even samples that traditionally require time-consuming pretreatment to handle unwanted constituents can be analyzed after simple pretreatment procedures such as dilution and filtration. The level of reliability attained in quantitative analysis is much higher than that attained conventionally with a low-wavelength UV method or a simple conductivity method. Superior linearity enables batch analysis in cases where constituent concentrations differ greatly and, consequently, helps reduce analysis time.
