A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Ash levels of 0. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Samples are ignited and ashed in a muffle furnace. NOTE 1—For more efficient ashing, the plastic sample should be in the form of powder or pellet. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.

The extended time so required for ashing is typically caused by a dearth of oxygen for oxidation of samples. Furthermore, a high wattage QAsh microwave oven, in conjunction with our high microwave-coupling heating plates, promotes rapid sample heating to the desired temperature. The system is driven by user-made methods that control the entire process, including an air valve that introduces fresh air into the heating chamber, thereby supplying the needed oxygen to ash the samples and, at the same time, pushing out by-product gases produced during ashing. If you are ashing oils, grease, wax, paraffin, polymers or other similar samples, QAsh will help you deliver better results faster. Different sample introduction modes are used, based on elements of interest and the matrix in question.
