Used PerkinElmer AAnalyst 800 Atomic Absorption Spectrometer

The Used PerkinElmer AAnalyst 800 Atomic Absorption Spectrometer​ represents a high-performance, integrated dual-atomizer platform that offers exceptional value on the secondary market. As a flagship model in its generation, it combines research-grade capabilities—notably Longitudinal Zeeman Background Correction​ and Transverse Heated Graphite Atomizer (THGA)​ technology—with the ruggedness required for routine high-throughput analysis. For laboratories needing to perform both trace (ppb-ppt) and minor element determinations across environmental, clinical, and materials science applications, a well-maintained AAnalyst 800 is a compelling investment.

Instrument Overview and Design Philosophy

The AAnalyst 800 is a fully integrated, PC-controlled spectrometer that unifies flame (FAAS) and graphite furnace (GFAAS) systems within a single benchtop chassis. Unlike modular systems, it features a motorized atomizer exchange that allows for software-controlled, tool-free switching between flame and furnace modes without breaking the vacuum or realigning optics. This design minimizes operator intervention and maximizes uptime. The instrument's architecture is built around the WinLab32™ for AA​ software platform, which provides comprehensive control, 21 CFR Part 11 compliance features, and advanced data management, making it suitable for regulated environments like pharmaceutical QC.

Core Technical Capabilities

1. Advanced Optical and Detection System

The spectrometer utilizes a high-resolution echelle grating double-beam optical system with a wavelength range of 190–900 nm. A key differentiator of the AAnalyst 800 is its use of a solid-state Array Detector, which captures the entire spectrum segment simultaneously, improving signal-to-noise ratio and analysis speed. The system includes an 8-lamp turret with simultaneous power supplies for Hollow Cathode Lamps (HCL) and Electrodeless Discharge Lamps (EDL), enabling automatic lamp selection, alignment, and预热 for multi-element sequences.

2. Superior Graphite Furnace Performance with Zeeman Correction

This is the standout feature for trace analysis. The AAnalyst 800 employs a Longitudinal AC Zeeman​ background correction system (as opposed to the more common deuterium lamp used in lower-tier models). This technology provides highly accurate background correction for complex matrices like blood, soil digests, and seawater, where structured molecular absorption is a major interference. The furnace system itself is a Transverse Heated Graphite Atomizer (THGA)​ with True Temperature Control (TTC), ensuring uniform heating across the tube and precise thermal profiles for minimal chemical interference and superior detection limits (e.g., sub-ppb for Pb, Cd, As).

3. Automated Flame System

The flame compartment features a high-sensitivity adjustable nebulizer, a polymer spray chamber, and a titanium burner head. It supports air/acetylene and nitrous oxide/acetylene flames with fully automated gas control and safety interlocks. The system is designed for high-throughput analysis of major elements with excellent precision.

Key Advantages of a Used Unit

• Cost-Effectiveness:​ A used AAnalyst 800 offers research-grade Zeeman and THGA capabilities at a fraction of the cost of a new equivalent instrument.

• Robustness:​ The integrated design and mature WinLab32 software ensure reliable operation with minimal downtime. Common wear parts (nebulizers, graphite tubes) are readily available.

• Method Continuity:​ For labs replacing an older PerkinElmer model (e.g., 4100, 5100), the AAnalyst 800 offers a smooth transition with similar operational logic and software environment.

Typical Applications

• Environmental Analysis:​ Ultra-trace determination of heavy metals (Pb, Cd, Hg, As) in water and soil per EPA methods.

• Clinical & Biological Research:​ Analysis of trace elements in blood, serum, and tissue samples with minimal sample volume.

• Food Safety & Pharmaceutical QC:​ Impurity testing and compliance with ICH Q3D guidelines for elemental impurities.

Purchasing Considerations

When evaluating a used AAnalyst 800, critical checks include:

• Furnace History:​ Inquire about the graphite furnace cycle count and check for any error logs related to temperature control.

• Zeeman Magnet Health:​ Verify the performance of the longitudinal magnet system through a diagnostic test.

• Software License:​ Ensure the transfer of the WinLab32 license and dongle is included.

• Cooling System:​ Confirm the integrity of the internal or external recirculating chiller.

In summary, the Used PerkinElmer AAnalyst 800 is a sophisticated analytical asset that democratizes access to Zeeman-corrected, furnace-based trace metal analysis. Its integrated automation and proven durability make it an outstanding choice for laboratories seeking to elevate their analytical capabilities without the capital expenditure of new equipment.
