EXPEC 4850 metals analyzer is a new high-performance full spectrum spectrometer developed by EXPEC Technology based on over 10 years of emission spectroscopy technology. This technology was first applied to the company's spectrometer M5000 . The instrument was released in 2009 and has passed more than 10 years of market testing and verification. Its stability and reliability have been tested by customers. The new EXPEC 4850 instrument uses a scientific research grade CMOS sensor as the detectors , follows the classic dual chambers Paschen -Runge type optical system design. Its excellent performance can meet the analysis needs of high-end users.

The dual-optics design can greatly improve the intensity of ultraviolet spectral lines and the measurement accuracy of ultraviolet elements without affecting the measurement of visible spectral lines. It also takes into account the advantages of high resolution and wide spectral wavelength range , with good performance for more elements.

An independently designed UV optical system that allows direct optical collection behind the spark stand , reducing optical intensity loss , improving the transmission efficiency of UV lines . It is specifically designed for measuring UV elements such as C , P , S , and N .etc , with higher grating lines for higher resolution.

The structure of the purer ultraviolet optical system with a small chamber (only 0 . 17L) is very simple and has no dead ends. Using an original argon purging technology , it can quickly flush air out to get higher argon purity and stronger ultraviolet optical detection capability , ensuring the analysis effect of ultraviolet elements.
