In the metallurgy, mechanical manufacturing, and precision casting industries, controlling the exact composition of chemical elements is a vital factor that determines product quality. To meet the increasingly strict standards of today’s market, Maxlab Equipment is proud to introduce the OES DF-700 Dongyi Photoelectric metal composition analyzer – a high-end spark optical emission spectrometer that delivers a comprehensive, ultra-fast, and absolutely precise measurement solution.

The OES DF-700 Dongyi Photoelectric metal composition analyzer is a next-generation spark optical emission spectrometer engineered and manufactured by Dongyi Photoelectric (DFAIC). The device utilizes high-resolution CCD sensor technology combined with an advanced digital excitation source system.

Model DF-700 is specifically designed for the rapid quantitative analysis of elemental components across various metal matrices, including Iron (Fe), Aluminum (Al), Copper (Cu), Nickel (Ni), Zinc (Zn), Titanium (Ti), and more. This instrument serves as a powerful asset for QA/QC laboratories, billet production facilities, foundries, and independent metal testing centers.

Unlike older generation spectrometers that use Photomultiplier Tubes (PMT) and are limited by a fixed number of optical channels, the DF-700 features an intelligent, staggered multi-chip CCD sensor array. This technology allows the equipment to capture the entire emission spectrum ranging from 140nm to 750nm. As a result, businesses can easily update and expand new analytical elements in the future via software updates without incurring costs for hardware modifications or upgrades.

Featuring a Czerny-Turner optical system design with a focal length of up to 400mm and a high-density holographic grating of 2400 lines/mm, the machine provides extremely sharp optical resolution. The device allows for the precise analysis of critical, short-wavelength non-metallic elements such as Carbon (C), Sulfur (S), Phosphorus (P), and particularly Nitrogen (N) at ultra-low (trace) levels. This ensures perfect quality control for high-alloy steel grades, stainless steel, or specialized cast iron.

Thanks to the computer-controlled digital excitation source, the spark discharge frequency of the machine can reach from 100Hz to 800Hz with an ultra-short pulse width of 200ns. The sample burning and quantitative result output process is completely automated, taking only 15 to 30 seconds per measurement. The intelligent algorithm integrated into the software helps the machine automatically calibrate inter-element interference, optimizing repeatability and minimizing errors to the lowest possible level.

The optical chamber system of the OES DF-700 Dongyi Photoelectric metal composition analyzer is designed to be tightly sealed, anti-vibrational, and highly insulated. This structure ensures that the machine operates durably even in harsh industrial workshop environments. Furthermore, Argon gas consumption during the testing process is optimized to a very low level, helping businesses maximize savings on routine operational expenses.
