Description

The Flame-Graphite Furnace Integrated Atomic Absorption Spectrophotometer AS2300 is a new product meticulously crafted by Optosky. The multimedia graphite furnace visualization system allows intuitive monitoring of the dynamic changes of the sample solution inside the graphite tube during drying, ashing, and burning processes. It facilitates the observation of the optimal position and depth for the autosampler capillary needle insertion into the graphite tube, as well as the placement of the platform inside the graphite tube, ensuring analytical accuracy and extending the graphite tube's lifespan.

The advanced optical design incorporates an integrated suspended vibration-isolation optical platform that enhances anti-vibration capability and prevents temperature changes from affecting the optical system, ensuring stable optical signals. It supports 85-position auto sampling and online dilution, significantly simplifying analytical operations and improving analytical efficiency.

Additionally, this instrument combines flame, graphite furnace, and hydride generation functionalities, allowing analysis from high concentration ppm levels to trace ppb levels without needing to switch atomizers. This greatly simplifies operation. The six-lamp automatic turret system enables rapid multi-element analysis. The AS2300 also features an advanced and reliable safety protection system, providing comprehensive safety for operators.flow cytometry, cell sorting, optical instruments, spectroscopic analysis, interference, metrology, holography, and physical experiments.
