Get Started

Most researcher’s first approach to neurotransmitter analysis can leave them feeling unsure where to start and overwhelmed. As a company founded and operated by scientific minds, we get it.

That is why we developed the HTEC-600, an HPLC-ECD (High Performance Liquid Chromatography – Electrochemical Detection).  The HTEC-600 offers pre-configured applications and protocols so your journey into neurotransmitter analysis is clear 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. 


” 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. “
