For more than 20 years Antec has been the world’s leading supplier of analyzers using High Performance Liquid Chromatography (HPLC) with Electrochemical Detection (EC). Validated applications for environmental, food, clinical and pharmaceutical analysis have been successfully developed using the ALEXYS LC-EC systems. With its ultra-sensitive Electrochemical Detectors Antec has become the key supplier for neurotransmitter analysis.

The ALEXYS product line is based on routine applications using HPLC with electrochemical detection. Dedicated and robust applications have been developed and validated. Neurotransmitters in brain or tissue, vitamins in blood, or aminoglycosides in pharmaceutical products, to mention a few.

The ROXY product line is not for routine analysis with a predictable outcome. It is a research tool in drug development, proteomics, genomics and several other fields. The potentiostat and flow cells are not for detection, but used to generate oxidation or reduction reaction products that are analyzed in mass spectrometry (MS).

HPLC/EC detection system configurations - Antec

For Clinical analysis of catecholamines sample volume is usually between 20 - 100 uL, therefore an ALEXYS with DECADE II SDC and standard bore HPLC has been the configured. For carbohydrates both pumps are used in a binary gradient, the aminoglycosides use a second pump for post column addition of sodium hydroxide.


Analyzers using High Performance Liquid Chromatography (HPLC) with electrochemical detection (SCD

The system uses Clarity, a fully featured data acquisition software with all the tools for automated data acquisition, calibration, processing and reporting. The ALEXYS is a HPLC system with electrochemical detection that has been designed to meet the highest demands for detection sensitivity and performance. Parallel detection schemes using multiple flow cells have been developed for time. Parallel analysis with multiple flow cells.
