Microwave-assisted digestion of organic samples: How simple can it become? Many papers recently published deeply exploit these instruments when applied for digestions of plants, animal tissues, foods, suet oil and pharmaceutical samples. Discover the most recent literature on the field.

The determination of trace levels of Hg is a must and frequently measurements are performed by converting Hg to a vapor and measuring its concentration either by atomic absorption or by atomic fluorescence. DMA-80 Direct Mercury Analyser has proved its superb performance in applications for a plethora of samples, such as animal tissues, atmospheric particulate, coal, fish, hair, sediments, soils, vaccines, etc. Even speciation analysis could be performed when associating the DMA-80 with a proper extraction procedure.

New paper publication titled "Evaluation of recycle and reuse of nitric acid from sample digests by sub-boiling distillation" has just been published on Microchemical Journal. In short, the article shows that acid digestion waste can be recycled (through a sub-boiling purification process) and reused, without compromising the quality of the analytical results, with clear benefits in costs and for the environmental health.
