  • Optimised in every detail
  • Designed for performance
  • Parallel analysis with multiple flow cells
  • Micro volume sample handling 

The ALEXYS is a HPLC system with electrochemical detection that has been designed to meet the highest demands for detection sensitivity and performance. The ALEXYS is easily upgradeable to micro-bore and capillary LC-EC. The system uses Clarity, a fully featured data acquisition software with all the tools for automated data acquisition, calibration, processing and reporting.

Guaranteed applications have been developed for the analysis of neurotransmitters such as noradrenaline, dopamine, serotonin and metabolites in microdialysates. Typically, picomolar concentration detection limits have been obtained in only a few microliters of sample. Parallel detection schemes using multiple flow cells have been developed for time, sample and experimental cost savings! The ALEXYS™ has proven its performance in routine analysis in clinical, food & beverage, environmental and pharmaceutical laboratories as well.

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.


ALEXYS HPLC EC Detection systems | Antec Proven Performance in ECD

As well as the data acquisition software, all pre-configured system files and tools for data analysis are supplied with the system and Application notes are published on the Internet. For some applications the choice of column, or chemicals and other accessories for sample pre-treatment are crucial for trouble free analysis.
