Furnace Atomic Absorption Spectrophotometer
Graphite Furnace Atomic Absorption Spectrophotometer
The Graphite Furnace Atomic Absorption Spectrophotometer is a brand-new product carefully developed by Optosky.
Its multimedia graphite furnace visualization system allows users to monitor the dynamic evolution of samples during the drying, ashing, and atomization processes inside the graphite tube. It also enables convenient observation of the autosampler capillary needle’s optimal position and insertion depth, as well as the platform’s position inside the graphite tube, helping ensure analytical accuracy and extend graphite tube life.
Featuring an advanced optical path design, the integrated suspended shock-absorbing optical platform improves shock resistance and minimizes the impact of temperature changes on the optical system, ensuring stable optical signals. The instrument supports 85-position automatic sampling and online dilution, reducing manual operations and improving analytical efficiency.
Additionally, its six-lamp automatic turret enables rapid multi-element analysis. An advanced and reliable safety protection system helps safeguard operators. With excellent performance, easy operation, accurate measurements, and stable operation, it meets a wide range of analytical requirements.
The instrument is widely used for quantitative elemental analysis in rare earth and precious metal analysis, environmental protection, water quality testing, alloy materials, building materials, medical and healthcare fields, universities, and scientific research.
