Graphite Atomic Absorption Spectrophotometer PG990G 

Features & Functions

• The unique design of the graphite furnace reduces the chemical interference effects and memory effects by uniformly heating the graphite electrode.
• The computer controlled heating program allows the user to select the best heating program for the analysis
• The optical temperature during the atomisation stage ensures the rapid heating and rapid analysis.This helps to extend the life of the graphite tube and enhances analytical accruacy.

Safety

• Argon gas pressure sensor
• Water flow sensor
• Over temperature sensor
• Broken graphite tube protection
