Capsule-Based Microwave Digestion [PDF]

open access: yesApplied Spectroscopy, 1995
Samples can be found in solid, liquid, or gaseous form. While one might argue that solids are the most ubiquitous type of sample analyzed, it would be difficult to defend the convenience of handling liquids. Indeed, most of our analytical instrumentation, from the electro-chemical through chromatographic to the spectroscopic, requires samples in liquid

Ultrasound assisted microwave digestion

open access: yesUltrasonics Sonochemistry, 2004
Simultaneous microwave and ultrasound irradiation is shown as a new technique for digestion of solid and liquid samples suitable for chemical and food analysis. Its application in analytical chemistry has been shown by decreases in digestion time: determination of copper in edible oils and total Kjeldahl nitrogen.
