Atomfair-AFS-MA369 Atomic Fluorescence – Liquid Chromatography Speciation Analysis System
Core Product Advantages
Flexible Upgrade & Seamless Connection: Adopt ICP-MS continuous sample introduction technology, no need to change the sample introduction method, and can achieve seamless connection with liquid chromatography of multiple brands. Only one docking module is needed to complete the efficient linkage between atomic fluorescence spectrometer and existing liquid chromatograph, giving full play to the effectiveness of existing laboratory analysis equipment, and expanding speciation analysis and detection capabilities with high cost performance.
Multi-functional Compatible Design: In daily work, the atomic fluorescence host can be independently used as a detector to accurately complete the total amount detection of elements such as arsenic (As) and mercury (Hg); the liquid chromatograph can also carry out conventional detection projects independently. When elemental speciation analysis is required, rapid combination can be achieved through the docking unit with flexible and convenient operation, meeting the diverse detection needs of the laboratory.
International Standard Compliance: Fully comply with relevant international testing standards, can accurately complete the detection and analysis of elemental speciation such as inorganic arsenic and organic mercury, and provide a strong guarantee for the international recognition of test results.
Applicable Test Items
It can accurately analyze different speciation and valence states of arsenic (As), mercury (Hg), antimony (Sb) and other elements in samples. Among them, inorganic arsenic is significantly more harmful to the human body than organic arsenic. This system can effectively distinguish and quantitatively detect such key speciation, meeting the strict testing requirements in food and other fields.

What are the minimum detectable amounts for different arsenic species using the Atomfair AFS-MA369 speciation system?
The system achieves distinct detection limits for arsenic species: As(III) ≤ 0.03 ng, DMA and MMA ≤ 0.05 ng each, and As(V) ≤ 0.5 ng. All species maintain a linear range spanning three orders of magnitude with precision ≤ 3% and analysis time under 10 minutes.
Can the Atomfair AFS-MA369 be coupled with existing liquid chromatographs from different manufacturers?
Yes, the system employs ICP-MS continuous sample introduction technology and requires only one docking module to achieve seamless connection with liquid chromatography systems from multiple brands. This preserves the utility of existing lab equipment and expands speciation analysis capabilities without requiring replacement of the chromatography hardware.
Can the atomic fluorescence host be used independently when not performing speciation analysis?
Yes, the atomic fluorescence host can operate independently as a detector for total element analysis of arsenic and mercury. The liquid chromatograph can also perform conventional separations independently. When speciation analysis is needed, the two instruments are rapidly combined through the docking unit, providing flexible laboratory operation.
The Atomfair-AFS-MA369 integrates atomic fluorescence spectrometry with liquid chromatography via a single docking module, enabling speciation analysis of As, Hg, and Sb without altering the sample introduction method. It supports independent operation as a total-element detector or LC detector, with minimum detectable amounts down to 0.01 ng for mercury species and precision ≤3%.
Positive
- Seamless LC integration: Uses ICP-MS continuous sample introduction technology, requiring no change to the sample introduction method, and connects to multiple LC brands via a single docking module, preserving existing lab equipment investment.
- Dual-mode operational flexibility: The AFS host can independently perform total element detection (e.g., As, Hg), while the LC can run conventional projects alone; rapid combination via the docking unit supports diverse speciation analysis needs.
Trade-offs
- Speciation-specific detection limits: Minimum detectable amounts vary by species, with As(V) and Sb(III) at ≤0.5 ng versus ≤0.03 ng for As(III), requiring method-specific calibration for low-level quantification.
- Analysis time constraint: All listed species require analysis times under 10 minutes, which may limit throughput for high-sample-count laboratories or demand careful chromatographic optimization to maintain precision.
