Getting started with neurotransmitter analysis can feel unclear, from selecting the right method to ensuring reliable results.
The HTEC-600, developed by Eicom, simplifies this process with a guided, turnkey HPLC-ECD system that combines hardware, application support, and expert guidance from start to finish.
All-in-one turnkey HPLC-ECD
Avoid the potential confusion caused that comes from individually configuring the multiple components required for neurotransmitter analysis. The HTEC-600 combines all of the key components required for hyper sensitive neurotransmitter analysis into one easily configurable system so you can get started immediately from the moment it arrives in your lab.

What researchers say
“The [HTEC] has been fantastic, it’s run beautifully, and it’s super easy to use.
I like that all of my settings can be controlled right here on the screen, instead of having to make method files within the software and uploading them to the system – that’s just too much work.”
– Sarah Ryan, Augusta University
