Agilent AAS 240Z Atomic Absorption Spectrometer Introduction

Product Overview

The Agilent AAS 240Z is a high-performance flame/graphite furnace atomic absorption spectrometer featuring an integrated dual-atomizer design for rapid switching between flame (FAAS) and graphite furnace (GFAAS) modes. Designed for precise quantitative analysis of trace metals in environmental, food, pharmaceutical, and geological applications, it delivers reliable results for demanding laboratory workflows.

Core Technical Features

1. High Sensitivity & Accuracy

   • Detection limits reach ppb levels in flame mode (e.g., Cu 0.001 mg/L) and ppt levels in graphite furnace mode (e.g., Cd 0.02 μg/L).
   • Optical double-beam system corrects baseline drift in real time, while the high-resolution monochromator (adjustable bandwidth: 0.2–2.0 nm) enhances interference resistance in complex matrices.

2. Intelligent & Efficient Operation

   • Fully automated atomizer switching: Transition between flame and graphite furnace modes in just 10 seconds without manual disassembly.
   • 8-lamp turret enables continuous multi-element analysis, with built-in intelligent wavelength calibration to minimize human error.
   • SpectrAA software supports 21 CFR Part 11 compliance, automating data processing and report generation.

3. Safety & Stability

   • Graphite furnace visual system (GFTV) monitors sample charring/atomization in real time, preventing overheating risks.
   • Flame sensors and gas leak detection modules ensure operational safety, complying with ISO 9001 and GLP standards.

Typical Applications

• Environmental Monitoring: Analysis of heavy metals (Pb, Cd, Hg) in water and bioavailable metals in soil.
• Food Safety: Detection of trace elements (Fe, Zn, Se) in grains and beverages, meeting GB 5009 series standards.
• Pharmaceuticals & Chemicals: Control of metal impurities in APIs (per USP <232>/<233>).

Industry Advantages

The 240Z is renowned for its modular design and low operating costs, with an argon-saving mode reducing inert gas consumption by 40%. Compared to competitors (e.g., PerkinElmer PinAAcle 900T), it excels in graphite furnace heating rates (up to 3000°C/s) and long-term stability (RSD <1%).

Note: Use high-purity acetylene (≥99.9%) and argon (≥99.999%), and regularly clean the burner head to maintain sensitivity.
