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
