Sample Preparation for ICP and AAS Analysis
In ICP and AAS analyses, the sample is dissolved and introduced as a solution. The method used for this step — fusion, microwave digestion or automation — directly affects both analytical accuracy and operator safety. Anka Analitik offers three distinct solution options.
Instrument Portfolio
The right method depends on sample type, laboratory workload and required analytical precision. Fusion, microwave digestion and automation address three distinct scenarios.
Method Selection
Technical Distinction
The fusion method (FX Series) completely dissolves the sample with flux, minimising matrix effects; acid digestion is insufficient for silicate and refractory oxide samples. Microwave digestion (QWave) and Vulcan operate on the acid digestion principle and are suitable for organic matrices, biological samples and environmental specimens.
We recommend selecting the method with full knowledge of your sample matrix and target elements. Contact our team for technical support.
Application Areas
Frequently Asked Questions
Open-vessel digestion is carried out at atmospheric pressure, typically on a hotblock; volatile elements (As, Hg, Se) can be lost and acid consumption is high. Closed-vessel microwave digestion (QWave) operates under pressure; the higher temperature and pressure dissolve difficult matrices, prevent volatile element losses and reduce acid volumes. The majority of EPA and ISO methods reference closed-vessel digestion procedures.
Vulcan is designed for laboratories with high daily sample numbers that need standardised, routine procedures. Its LIMS integration and 7 reagent lines minimise operator intervention, improving both reproducibility and reducing chemical exposure. It provides advantages in process consistency for laboratories undergoing accreditation (ISO 17025).
No. The FX Series supports both XRF glass disc preparation and ICP/AAS solution preparation. In XRF applications, the sample is fused with flux and poured into a glass disc mould. In ICP/AAS applications, the fused material is dissolved into a dilute acid solution. This dual use makes the FX Series a cost-effective choice for mixed analytical laboratories.
