application
The graphite furnace atomic absorption spectrophotometer AS2200 is a brand new product carefully built by Optosky.
The multimedia graphite furnace visualization system can visually monitor the dynamic evolution of the sample liquid during the drying, ashing, and burning processes inside the graphite tube, and conveniently observe the optimal position and depth of the capillary needle of the autosampler entering the graphite tube, and The position of the platform inserted into the graphite tube ensures the accuracy of analysis and the life of the graphite tube.
Adopting advanced optical path design, the integrated suspended shock-absorbing optical platform improves shock resistance, avoids the impact of temperature changes on the optical system, and the optical signal is relatively stable; it can support 85-bit automatic sampling and online dilution, greatly reducing analysis operations and improving analysis efficiency.
In addition, a six-lamp automatic turret system is used to provide rapid analysis of multiple elements. It also has an advanced and reliable safety protection system to protect the safety of operators in an all-round way. It has excellent performance, easy operation, accurate indicators and stable performance. It can meet many common needs and is deeply loved by the majority of users.
It is widely used in quantitative analysis of elements in rare earth analysis, precious metal analysis, environmental protection, water quality testing, alloy materials, building materials, medical and health, universities and other scientific fields.
