A Guide to Ashing & ISO 1171
Ashing is the process of removing organic material from a sample before analysis and is widely used in the food and petroleum industries. The processes of ashing can generally be split into two categories: wet ashing and dry ashing. Wet ashing removes organic material from a sample employing a liquid phase reactant such as combinations of acids. Dry ashing is achieved through the controlled ...

What's causing toxicity in sediments? Results of twenty years of toxicity identification and evaluations (TIES)
Sediment Toxicity Identification and Evaluation (TIEs) methods have been used for twenty years to identify the causes of toxicity in sediments around the world. We summarized and categorized results of 36 peer‐reviewed TIE studies (67 sediments) into non‐ionic organic, cationic, ammonia and “other” toxicant groups. We further categorized results by whether the study was performed in fresh‐ or ...
