|
| ||
| Digestion Type: | |||
| Your choices are... | |||
| Acid Digestion | In acid digestion the sample is digested under elevated pressure (100-500 psi) and temperature (50-180 degrees C) conditions using conventional acids, such as nitric and hydrochloric acids. | ||
| Microwave Digestion | Microwave energy heats microwave-absorbing reagents containing a sample inside a pressurized, microwave-transparent container. Pressurization allows higher temperatures to be achieved, thus increasing the speed of digestion. Pressure and temperature inside the control vessels may be monitored and used to determine the amount of microwave energy applied. | ||
| Other | Other unlisted or proprietary method. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Reaction Type: | |||
| Your choices are... | |||
| Open Flask | The reaction takes place in an open container. Open vessel digestion is classically the most commonly used method. | ||
| Closed Flask | The reaction takes place in a closed container. The elevated pressures that can be achieved in closed reaction vessels decrease digestion time. | ||
| Search Logic: | Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
