Conclusion
The PerkinElmer PinAAcle 900H AA spectrometer features a
closed-furnace design that is sealed at both ends with easily
removable bayonet-mount windows. The closed design is a
prerequisite for controlled, reproducible analytical conditions.
The separate, independently controlled external and internal gas
streams provide maximum flexibility, tube life and sensitivity.
The PinAAcle 900H system uses enhanced power control circuitry
to maintain a uniform heating rate, so no matter where a system
is located, it provides outstanding and consistent performance.
The PinAAcle 900H, equipped with an HGA graphite furnace,
has demonstrated its capabilities in handling different digested
food sample matrices. The system provides the superior sensitivity
required for heavy-metal testing in food matrices, with excellent
accuracy, as observed from the recovery studies.
