High sensitivity
HPLC-ECD System
HTEC-600
“ Ultra-High Sensitivity and Stability
★ Ultrasensitive, 30 fg of dopamine, serotonin
★ Eicomʼ s Innovative Cell Design System Design with Pulsation Free Pump
★ Temperature Regulated System with Both Cooler and Heater Optimized Applications for the ECD
As you can see, the sensitivity could not be achieved only by the detector.
All-In-One With A Small Footprint
The liquid feed pump, degasser, thermostatic chamber, and electrochemical detector
have been integrated. This makes it possible to make use of analysis applications for other detectors, such as flow speeds exceeding 500 μL/min.
* The new model can be used with long columns which could not be placed in a chamber for the previous model, allowing it to support a wider range of analysis applications.
“ PURGE function
★ PURGE function
This function allows for high-speed liquid feeding. The operation time can be set, and there is no need to be concerned over liquid drying out.
Air bleeding and liquid exchanging can be performed automatically, significantly improving pump errors (the most frequent general issue with HPLC).
★ TIMER function
This function can turn the pump and ECD ON/OFF individually using time-based control. The operation time can be controlled,
allowing consumption during the mobile phase to be minimized. This function can be used to operate the pump and ECD efficiently,
allowing for trouble-free sample measurement.
★ L.SWITCH function
ELS-500 can be controlled from HTEC-600. Eliminating contamination during the later stage of a chromatogram can streamline amino acid
analysis or analysis for samples in which contamination is produced comparatively more often. The ease-of-use provided by ELS-500 is a
major advantage when conducting experiments.
Easy to Maintain
The simple compact design of the HTEC-600 (HPLC-ECD) allows for easy maintenance. No tools to access the working electrode/ Easyto clean or change the working electrode.
★Dopamine ★DOPAC ★HVA ★3MT ★L-DOPA ★Norepinephrine ★MHPG ★Normetanephrine ★Epinephrine
