DECADE Elite – Electrochemical Detector
I’m Sensitive – I’m Impressive – I’m Elite
- Most sensitive electrochemical detector
- UHPLC & HPLC compatible
- Temperature stabilized cell/column compartment
- ADF (advance digital filter) to improve S/N ratio
- Wide selection of flow cells
Ultra High Performance Liquid Chromatography (UHPLC) has gained much interest in many application areas. Small particle (sub 2 um) stationary phases with high separation efficiency makes it possible to use shorter columns and a fast analysis time while maintaining excellent separation. The DECADE Elite has been developed to meet the demands in fast analysis, as to detection sensitivity, acquisition frequency and temperature of separation.
The DECADE Elite uses Antec’s workstation concept, keeping the column and flow cell (separation and detection) at a very accurate and stable temperature. Stable working conditions are a prerequisite for trace analysis, without stability no sensitivity! In addition, the DECADE Elite has ADF (advanced digital filter) which is a noise elimination algorithm specially developed for electrochemical data. It further improves the detection limit, depending on conditions up to a factor 200. Detection sensitivity is especially eminent in neurotransmitter analysis. Together with the new SenCell bottom line detection limits down to 30 pmol/L have been obtained in 2 µL sample. Antec provides a number of amperometric flow cells with different features for specific applications. The flow cells are certified and warranted up to 5 years (glassy carbon type).
The DECADE Elite is able to control up to 4 cells for high throughput applications or electrochemical pre-reduction (e.g. vit-K, Q10 etc). The detector has a pulse mode for carbohydrate analysis using the traditional 3-step pulse and more advanced 4 or 5 step pulses. The scan mode is available for method optimization, to characterize the electrochemical behaviour of a substance of interest.
|The DECADE Lite has the same performance as the DECADE Elite. It has an integrated oven with Faraday cage, it is equipped with the superior ADF and has control for one flow cell (single cell control). The DECADE Lite has DC mode only and is operated by PC control software (free). The DECADE Lite is compatible with all Antec flow cells. An electrically actuated injector or a manual injector (standard or micro) are optional.|
The DECADE Elite (and Lite) is controlled by Clarity (rev 6) and the new Dialogue Elite.

Adjustable Spacer Technology (AST)
The SenCell™ is a new generation electrochemical flow cell specifically designed for highest sensitivity. The tool free assembly and the continuously adjustable working volume guarantee ease of use and fast stabilization. The volume of the cell is small and can be adjusted between roughtly 0 and 300 nL. In addition, the cell can withstand a pressure of several bars, making the cell ideally suited for use in (U)HPLC with Electrochemical Detection (ECD).
To realize the highest detection sensitivity, the cell design is based on the confined wall-jet principle. A three-electrode configuration is used consisting of working electrode (WE), reference electrode (REF) and auxiliary electrode (AUX). The AUX is kept at precisely the same potential as the reference electrode via a voltage clamp, compensating for any polarization effects that might occur at the electrodes. In addition, utmost care has been devoted to the quality and finishing of the electrode material so that the highest sensitivity with fast stabilization is achieved, making the cell ideally suited for ultra-trace analysis in (U)HPLC, micro- and capillary LC/ECD.
Adjustable Spacer Technology – AST
The new design is using Adjustable Spacer Technology (AST), the use of polymeric gaskets (spacers) is now obsolete. The AST is a build-in micropositioner for the working electrode relative to the inlet. To adjust the electrode position simply turn the micropositioner mechanism in the cell with an adjustment key (which is provided). By minimizing the electrode distance (‘spacer’), more signal will be ‘squeezed out’. For many applications this will improve the detection sensitivity.
 US Patent nr. 9,310,330
|Adjustment from position 2 to 1: turn counter clockwise with the provided adjustment key.||Adjustment of the SenCell from position 3 to 0.5 results in a 2,5 fold increase in signal.|
The SenCell is available with 3 different color coded reference electrodes that can be easily exchanged to fit any application.
Ease of use
The tool free, easy-lock screw assembly allows for fast (dis-)assembly. Furthermore the AST guarantees for highest sensitivity (S/N) and fast stabilization.
