Digestion of Steels and High-performance Alloys for ICP Analysis

Multiwave 5000/Rotor 20SVT50 offers the opportunity to digest several demanding inorganic samples such as low and high alloyed steels or Ni-based alloys with the convenience and safety of the SmartVent technology.

The precise and accurate determination of alloying constituents in steels and nickel-based alloys is analytically demanding, but of great commercial significance for steel and high performance metal industries.
Closed vessel microwave digestion using Multi-wave 5000 followed by ICP-OES analysis provides an accurate and reliable solution. This wet-chemical method of analysis is used as an arbitration procedure as well as an important calibration method for X-Ray spectrometers to ensure high accuracy.
Rotor 20SVT50 in Multiwave 5000 offers the well-established SmartVent technology at an advanced temperature level of up to 250 °C, thus providing excellent digestion quality for hard to digest metals requiring higher temperatures.
The SmartTemp sensor for internal temperature measurement enables quick temperature control which is especially important for reactive samples.
Up to 20 vessels per run allow the highest throughput compared to any other high performance rotor. Convenient tool-less handling makes Rotor 20SVT50 the ideal configuration for demanding samples in Multiwave 5000.
In order to demonstrate the suitability of Multiwave 5000 for the digestion of steels and high performance alloys several certified reference materials were digested. Afterwards the specified elemental concentrations were determined via ICP-OES, whereas the accuracy is 1-3 % for main components and 5-20 % for trace elements.
