Shimadzu AA-7000 Atomic Absorption Spectrophotometer

Description

The AAS AA-7000 series incorporates two background correction functions, the D₂ method (deuterium lamp method) and the SR method (high-speed self-reversal method), enabling selection of the appropriate method for the measurement sample.
