A well-recognized and effective technique employed by testing labs for trace metals analysis requires acid digestion of samples in a closed-vessel microwave system followed by elemental analysis by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS). Compared to more traditional digestion techniques, such as hot plate and hot block, microwave technology enables chemists to perform acid digestions of a variety of matrices at much higher temperatures and pressures. These factors maximize data quality and minimize sample turnaround time. Traditional microwave digestion systems using individual pressurized reactors are utilized by various laboratories and industries across the world. However, new advancements in microwave technology can greatly improve the sample preparation process for commercial testing labs and positively impact sample throughput and work flow efficiency.

A study was conducted to demonstrate the use of the direct mercury analyzer (DMA-80) from Milestone Inc., Shelton, CT), US, to determine total mercury content in fish and biological tissue. The DMA-80 featured circular, stainless steel, and interchangeable 40-position autosampler for unlimited throughput and accommodated nickel and quartz boats depending on the requirements of the application. All mercury species were reduced to Hg(0) and carried along with to a gold amalgamator where the mercury was selectively trapped. All non-mercury vapors and decomposition products were flushed from the system by the continuous flow of gas. The amalgamator was heated, releasing all trapped mercury to the single-beam, fixed-wavelength atomic absorption spectrophotometer. The samples were re-analyzed on the DMA-80, defrosted, and placed at varying weights into nickel sample boats and loaded into the autosampler for analysis. Source

SRC technology changes the traditional work flow of microwave digestion by removing the limitations of closed-vessel systems. Sample throughput is up to two times higher, with significant labor savings due to reduced vessel handling and cleaning. No batching of samples into runs of the same matrix is required, which is a major benefit for laboratories that digest multiple sample types. Method development is largely eliminated, and the high temperature and pressure capability means that superior digestion quality is achieved for the more challenging samples. Consumables costs are significantly lower, and digestion acid usage is reduced by 50%. Finally, the small size of the UltraWAVE makes it as convenient to install as a closed-vessel system. Source
