Persee A3G Atomic Absorption Spectrophotometer, Persee (CAT#: STEM-S-1412-LGZ)

The manufacturer of Persee A3G Atomic Absorption Spectrophotometer is Persee. Model is A3G. A3 Atomic absorption spectrometer is a high -performance automation instrument designed to meet the requirements of modern laboratories. Because of its generality and performance, it can be used for widespread application. The instrument has three configurations. The A3F instrument is equipped with flames, the A3G instrument is equipped with a graphite furnace, and the A3FG instrument is also equipped with flames and graphite furnaces. Its positioning is completely controlled by the embedded computer system and AA-Win Pro software. The three flames are available for users to choose from, and air/acetylene is a standard configuration. This flame can be used for almost all standard elements, while N2O/acetylene and air/liquefied petroleum gas (natural gas) are a more harsh element choice. All three flame configurations provide comprehensive safety protection encoding burner. Graphite head is fixed in the light path to maximize performance and eliminate drift. The precision feedback system accurately controlled the temperature of the horizontal heating graphite tube. As a standard, it provides armal solution coating platform tube to improve performance and eliminate many analytical problems related to this technology. Flames and graphite furnaces can change the general AA Win software through simple choices.
