DITEE Scien fic
 Since 1960
Inherited from the first genera on of
spectrometer experts in China

The DlTEE SWORD 500 Induc vely Coupled Plasma Op cal Emission Spectrometer (ICP-OES) is the result of the
con nuous efforts in research and development by the spectroscopy experts at the Guangdong Academy of
Sciences (GDAS) for over 60 years. This advanced instrument is equipped with a Rowland Circle op cal system
designed to minimize matrix interference, along with cu ng-edge CMOS detectors for full-spectrum collec on. It
offers excellent stability, low limit of detec on, rapid analysis, and low opera ng costs.

The DlTEE SWORD 500 can be op onally equipped with a laser abla on solid sampling system, offering a unique and
cost-effec ve LA-ICP (Laser Abla on Induc vely Coupled Plasma) spectrometer.

The DlTEE SWORD 500 ICP-OES is widely used for sample analysis across various applica on fields, including new
energy, nuclear industry, metallurgy, rare earth and magne c materials, geology, environment, petroleum, new
chemical materials, agriculture, food, healthcare, biology, marine, and water quality. This instrument can quickly
and accurately detect approximately 70 elements, ranging from trace to major concentra ons.
