Features
Fully controlled by PC, allowing flexible selection of flame and graphite furnace atomizer (optional).
Integrated floating optical platform design enhances optical system shock resistance and ensures long-term stability of optical signals.
Eight light stands can be automatically changed, and preheating of eight element lamps simultaneously optimizes the performance of hollow cathode lamps.
Position adjustment: optimal height for the flame burner, with automatic front and rear positioning.
Fully automated wavelength scanning and peak searching.
Complete safety chain protection equipment: warning and automatic safety protection against incorrect burners, gas leakage, low air pressure, and abnormal flameout.
Deuterium lamp and self-absorption background correction.
Data processing: powerful database with over 500 data storage and cut-off functions; results can be stored in Excel format, and testing methods and results can be easily retrieved.
Measuring method: flame absorption and emission methods.
Result printing: parameter printing, data result printing, and diagram printing.

Complete Automatic Control System
With software support, the following operations can be easily performed:
Element lamp selection
Lifter up/down/front/rear adjustment
Optical energy adjustment
Slit selection
Wavelength scanning and peak search
Atomizer selection
Background correction method setting
Gas flow control
Automatic flame ignition and extinction
Graphite furnace test method setting

Advanced Graphite Furnace Temperature Control Technology
The use of PID technology effectively minimizes the impact of voltage fluctuations and resistance changes on the temperature rise process, ensuring more accurate control. The 3ms/time fast sampling technique improves the accuracy and reliability of test results.
Fast heating capability increases flexibility for different elements.
Operates on a standard 220V power supply without requiring a 380V dynamic power source.
Up to 20 levels of maximum procedure heating settings for easier and more convenient testing of various samples.
Three adjustable gas flow levels to meet diverse application needs.
Timely alarm when gas or water is insufficient to prevent equipment damage and measurement errors.

Safe, Reliable, and Convenient Flame System
EPC controls acetylene flow accurately and offers easy operation.
Efficient atomization system provides higher sensitivity.
The entire system includes a fire safety mechanism that alarms and automatically cuts off gas if there is a power failure, abnormal flame, or mismatched burner, ensuring operator and equipment safety.

Multi-functional Software Workstation
Supported on Windows XP/2000/NT operating systems.
Rich menu options provide convenience for users.
Easy switching between menus makes operation more intuitive.
Multiple analytical correction methods offer users more choices.
Default parameters allow even beginners to perform normal operations.
Flexible storage, editing, and printing options provide full user support.
