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
