Instrument introduction:


AES998 is equipped with a high-energy spark plasma power system and an optical system with high focal length and resolution in the industry to achieve a high level of accuracy, repeatability, and stability of high-speed metal detection.

1.High energy spark plasma power system

High-energy-range, high-reliability plasma power systems deliver high-quality electrical sparks.

It can accurately analyze various types of substrates, and has unique advantages in the analysis of difficult-to-excited cast iron and cast aluminum materials.

2.High-performance optical system

The optical system AES998 with high focal length and resolution in the industry provides a powerful spectral analysis platform with high spectral accuracy and reliability; the optical system is stable and the correction period is long.

3.Optimize the design of the excitation table

The dynamic and static argon gas flow design is used to ensure that no heat engine is needed during the analysis, and the samples are analyzed in time; and the low gas flow consumption during standby, which saves argon.

The optimized argon purge gas flow design effectively discharges metal vapor and promotes stable discharge of electric sparks.

The protective door design effectively isolates noise and electromagnetic interference, prevents false excitation of unloaded samples, and escorts testers.

4. Convenient user experience

From sample processing to instrument operation, the process design is simple and easy to operate, and part-time personnel can perform daily operations.

WINLAB software system visual operation design, operation and maintenance functions at a glance, testers can quickly learn and operate.

5, hardware status monitoring and protection

Real-time monitoring and display of instrument status, automatic protection of instrument system when status range is exceeded
