AA320N Double Beam AAS: Multi-Matrix Heavy Metal Analysis
Supplier:TAOMSUN ｜Overseas Tech Support:METICULAB (Korea) ｜ISO-certifiedManufacturing Partner
Atomic absorption spectroscopy is a well-established quantitative technique for heavy metal testing in environmental, food and agricultural laboratories. Water, food digestates and soil extracts differ greatly in matrix complexity. Clean water samples are easy to measure, while food and soil samples contain large amounts of organic residues, salts and interfering co-existing elements, which may cause baseline drift and false positive results. The AA320N double beam atomic absorption spectrophotometer provides a modular solution for multi-scenario heavy metal detection.
1. Why Double Beam AAS for Multi-Scenario Testing
Double-beam optical design automatically compensates light-source drift, temperature-caused wavelength drift and circuit drift to achieve excellent baseline stability. Hollow-cathode lamps do not require lengthy warm-up time; samples can be measured rapidly right after instrument startup, suitable for multi-element and fast batch sample analysis.
AA320N optical systemDouble beam, Czerny-Turner monochromator, total-reflection optical path
Background correctionDeuterium lamp background correction, >30× correction capacity
Standard flame package100 mm titanium alloy burner, high-efficiency glass nebulizer
Spectral bandwidth6 adjustable steps: 0.2 nm ~ 5.0 nm
2. Core Performance Parameters
|
1. Characteristic concentration (Cu) Mass concentration which produces 0.0044A absorbance. AA320N:≤0.04 μg/mL/1%. |
2. Detection limit (Cu) Lowest detectable concentration for copper standard solution. AA320N:≤0.007 μg/mL. |
|
3. Wavelength range Full working wavelength range for common heavy metals. AA320N:190 nm ~ 900 nm. |
4. Baseline stability Baseline drift within 30-minute continuous running. AA320N:±0.005 Abs/30min. |
|
5. Deuterium background correction Eliminate matrix absorption interference. Correction range:＞30 times. |
6. Spectral bandwidth Six-step adjustable slits:0.2 nm - 5.0 nm. |
|
7. Wavelength accuracy AA320N:≤±0.5 nm. |
8. Wavelength repeatability Single-direction repeatability:≤0.3 nm. |
3. Solutions for Multi-Scenario Detection
💧 Water Testing (Environmental / Wastewater):
For routine testing, the standard Flame Atomization System with a 100mm titanium alloy burner handles large batches rapidly. For trace elements in drinking water, the optionalGA3202 Graphite Furnacedelivers absolute sensitivity up to 10 ⁻¹⁰ to 10⁻²⁰ grams.
🌾 Food & Agricultural Products:
Food digestates have high organic and salt matrices. The AA320N features strongDeuterium Lamp Background Correction (>30 times), effectively deducting background absorption for accurate Pb and Cd analysis. For As, Hg, and Se, the optionalHydride Generatorlowers the detection limit to ppb level.
🪨 Soil & Solid Waste:
For complex soil matrices, built-in microcomputer supports multiple linear/non-linear curve fitting. Adjustable spectral bandwidth (0.2nm-5.0nm) effectively avoids spectral interference from co-existing elements such as Fe and Al.
4. Available Configurations
1. AA320N (Basic):Built-in microcomputer and LCD. Ideal for routine QC labs and in-house testing.
2. AA320NCRT (Professional):Includes main unit + PC + Printer + Workstation Software. Supports data traceability and management for third-party labs.
