Benefit
Complete digestion and dissolution
The more rigorous digestion conditions facilitate complete decomposition of the sample, ensuring that all target elements are in solution, even for the toughest and most chemically stable samples.
Low blanks and dilution
The use of low acid volumes or diluted acids in combination with high temperature reduces blank levels and dilution factors.
Low residual carbon content
Complete digestion of the sample matrix also ensures the lowest residual carbon content, thereby reducing polyatomic-based interferences during the analysis.
Larger sample mass
The combination of a wide pressure range and accurate digestion control enables the safe digestion of larger sample masses—even for very reactive samples.
At the core of the ultraWAVE 3 is the Single Reaction Chamber (SRC) — a stainless steel vessel lined with PTFE-TFM, which serves as both the microwave cavity and the digestion chamber. Samples and reagents are placed in vials and lowered into the liner containing a water-based solution to ensure uniform temperature distribution.
The chamber is pressurized with an inert gas to prevent boiling, element loss, and cross-contamination. Microwave energy then heats the system, while the temperature of the vessels is continuously monitored by non-contact sensors.
A water-cooling system keeps the steel chamber cool and enables rapid cooling before automatic pressure release. At the end of the process, the chamber opens and the fully digested samples are ready for dilution and analysis.
Technology inside. Performance outSide
The development of a truly impactful next-generation SRC-based microwave digestion system required the examination of every aspect of the hardware, software, user experience, and economics of the existing system.
ultraWAVE 3 is the culmination of a multitude of both major and minor changes that impact each of these aspects in meaningful ways.
Simplified handling
The vials and racks of ultraWAVE 3 are specifically designed to reduce assembly and disassembly time. The operator has only to place loose-fitting caps on the vials and the rack is ready for the digestion process. This approach eliminates the operator time required for closing and opening of the vessels, typically involved with the rotor-based systems.
The wide selection of racks and vials enables to match the detection limit, productivity, and application requirements of modern laboratories. Racks are available with different capacities to fit any sample type and mass. Vials are available in high-purity PTFE-TFM, high-purity quartz, and common laboratory glass (disposable) to address the detection limit and application needs of every lab.
Avoid vessel cleaning and reduce operator time
Rotor-based systems require digestion vessels with a complex construction to contain the elevated pressure within each vessel. Conversely, the SRC approach ensures equal pressures between the inside and outside of the vials, so vials can withstand elevated pressures using a much simpler construction. Thanks to this unique capability, the SRC technology even enables the use of inexpensive disposable glass tubes. This approach is commonly implemented for more routine applications and allows complete elimination of the tedious vessel cleaning step and concern for potential memory effects.
ultraWAVE 3 reduces hands-on labor time up to 50%. Several steps are done automatically by the system, such as the closing and venting of the chamber and automatic sealing of the vials, which reduces the operator time, raises the productivity and the safety of operation.
