What is a possible cause of low recovery when using the Metals prep set Product # TNT890?
Low recoveries when using Product # TNT880
The most common cause of low recoveries when digesting samples that contain metals is elevated pH. The pH of the sample should be less than one after the addition of reagent A. Samples that have a higher buffering capacity or a higher pH may need to have the pH adjusted before using the Metals prep set, Product # TNT890.
