Labmate Atomic Absorption Spectrophotometer LMAAS-A109
Labmate Atomic Absorption Spectrophotometer LMAAS-A109 provides a Cu detection limit of less than 0.006 µg/mL. Designed with dual atomization modes, it supports both flame and graphite furnace analysis. The instrument incorporates a single-beam optical system and advanced background correction using D2 and self-absorption methods. Multiple safety sensors, including gas flow, pressure, flame, and furnace monitoring, ensure reliable operation.
