Sample Preparation for Elemental Analysis with the Anton Paar Multiwave Series

Feb 06 2024

For several decades, atomic spectroscopic techniques have been predominantly used for trace elemental analysis of all types of samples. These atomic spectroscopic techniques work best when the analyte is presented as an inorganic, ionic species dissolved in a diluted mineral acid. A suitable technique for sample preparation must therefore prepare uniform, acidic solutions from many different types of sample. Microwave digestion has established itself as a reliable and effective means of sample preparation thanks to effective heating, precise reaction control, and high temperature and pressure tolerance. In our book, “A Chemist’s Guide to Sample Preparation,” you can find out more about the principles and benefits of microwave digestion.

Anton Paar's Multiwave microwave digestion systems offer fast, safe, and reliable sample preparation for a wide range of matrices, including pharmaceutical, biological, and environmental samples. Applications range from routine analysis, where sample throughput determines the productivity of an analytical facility, to demanding samples, which are difficult to digest. Different device concepts let users select the ideal system for their analytical task, with even more options to tailor the instruments to their requirements.

Multiwave 7101/7301/7501, a versatile series of PDC-based microwave digestion systems, are designed for efficiency and cost-effectiveness in meeting diverse analytical needs. Specifications of up to 300 °C and 199 bar ensure comprehensive digestions for both routine and demanding samples. Operators can customize their systems with seven different racks accommodating vials ranging from 7 mL to 80 mL, allowing for acid digestion of up to 4 g per position. Vial options include borosilicate glass for routine applications, quartz for low blank values and detection limits, PTFE-TFM for hydrofluoric acid digestions, and sealed quartz vessels for extremely volatile analytes. This versatility enables efficient and tailored sample preparation across various analytical requirements.

Multiwave 5000 is a versatile microwave reaction platform which can be configured with different rotors to yield the perfect system for your samples. Not only acid digestion, also microwave-assisted solvent extraction, protein hydrolysis, leaching, and even microwave synthesis is possible in this versatile instrument. SmartTemp and SmartVent technology have led to SVT and HVT vessels with unprecedented ease-of use. SmartVent allows for safe release of reaction gases during digestion to maintain higher temperature levels for better digestion quality, whereas SmartTemp monitors the internal temperature of each vessel in real time. The instrument also features a large touchscreen display and a library of over 600 methods, which covers all relevant norms and standards.
