摘要： A method of element testing is disclosed that includes the steps of weighing a sample, pressing the sample between pads, applying microwave radiation to the sample and pads in the presence of a microwave susceptor material and ashing the pressed sample, adding the pads and the ashed sample to an acid, and forwarding filtrate from the pad-sample-acid mixture to a spectrometer.
