Agilent G8434AA - AAS 280FS - 280Z AA G8434AA

The Agilent 280FS AA (catalog G8434AA) is a fast sequential flame atomic absorption spectrometer designed for multi‑element analysis in environmental, food, agriculture and high‑throughput laboratories. It performs automated, multi‑element determinations from a single sample aspiration and includes features such as automatic lamp selection, a programmable gas box and D2 background correction to improve routine productivity and data quality.

Key Features:

• Fast Sequential (FS) operation with 8‑lamp capability
• Determine 10 elements per sample in less than 2 minutes (manufacturer claim)
• Automatic lamp selection, programmable gas box and D2 background correction
• Supports UltrAA high‑intensity lamps — up to 40% increased sensitivity; typical lamp lifetimes >8000 mA·hours
• Includes Mark 7 atomization system (typically >0.9 Abs from 5 mg/L Cu; precision typically <0.5% RSD from ten 5 s integrations)

Advantages:

• High throughput — greatly reduces analysis time and sample consumption by measuring multiple elements from a single aspiration
• Improved sensitivity — UltrAA lamps and premium optics lower detection limits and reduce baseline noise
• Better accuracy and precision — online internal standard corrections and Mark 7 atomizer performance improve results for challenging samples
• Lower running costs — Fast Sequential and PROMT modes cut analysis time and gas consumption, reducing operational expense
