Agilent 280FS AA

Price Range: $40,000 – $60,000 Best For: Speed and High Throughput

The Agilent 280FS AA remains a dominant force in high-throughput environments due to its Fast Sequential (FS) mode. Unlike traditional AAS systems that analyze one element at a time across all samples, the 280FS measures all specified elements in a single sample aspiration. This workflow operates similarly to an ICP-OES system but at a fraction of the cost, making it the premier choice for laboratories prioritizing speed.

Key Specs:

• Throughput: Measures up to 10 elements per sample in less than 2 minutes.

• Lamp Turret: 8-lamp capacity with automated selection.

• Optics: Narrow-beam optics for maximum light throughput.

• Atomization: Mark 7 flame atomization system.

• Background Correction: High-speed Deuterium correction.

Performance & Applications: Operational efficiency is the core strength of the 280FS, which can cut analysis time by up to 50% compared to conventional AA instruments. This speed reduction drastically lowers gas consumption and sample waste, providing long-term operational savings. It is highly relevant for mining, agriculture, and contract laboratories where hundreds of samples must be processed daily for a standard suite of elements. The Mark 7 spray chamber is designed to handle difficult matrices with high total dissolved solids (TDS) without blockage, ensuring consistent performance in rugged industrial applications.

PerkinElmer PinAAcle 900T

Price Range: $65,000 – $85,000+ Best For: High-End Sensitivity and Dual Analysis

The PerkinElmer PinAAcle 900T is a sophisticated high-end instrument that integrates both flame and longitudinal Zeeman graphite furnace atomizers into a single, compact chassis. This "stacked" design eliminates the need to physically swap atomizers or align mechanical parts, providing seamless transitions between high-concentration and ultra-trace measurements. It represents the gold standard for laboratories requiring sub-ppb detection limits and maximum uptime.

Key Specs:

• Design: Stacked flame and transverse graphite furnace (no mechanical changeover).

• Background Correction: Longitudinal Zeeman for furnace; Deuterium for flame.

• Camera: TubeView™ color furnace camera for real-time monitoring.

• Optics: True double-beam system with fiber optic light efficiency.

• Throughput: High-speed scanning capabilities.

Performance & Applications: The PinAAcle 900T is engineered for research and strictly regulated industries such as pharmaceuticals and clinical toxicology. The inclusion of the TubeView camera allows operators to verify the probe position and drying stages inside the graphite tube, eliminating errors during method development for complex biological matrices. Its superior sensitivity makes it the ideal instrument for detecting toxic trace metals like arsenic, lead, and cadmium in blood, serum, or high-purity chemical reagents where accuracy is non-negotiable.
