Bottle contains 100 mL of matrix modifier.
Matrix modification decreases the volatility of the analyte element and prevents its loss during thermal pretreatment. This also allows application of higher pretreatment temperatures for better matrix removal. It also increases the volatility of matrix components and promotes their removal before atomization.
PerkinElmer furnace autosamplers feature automatic matrix modification with the ability to apply one or more matrix modifiers sequentially or simultaneously.
Refer to Technical Note “THGA Graphite Furnace AA – Automatic Matrix Modification for Improved Analytical Quality and Sample Throughput” for information on preparing the most common matrix modification solutions.

The matrix modification technique is a very important feature in the concept of interference-free trace metal determinations. Applying this technique, the chemical forms, and thereby the physical properties, of the element under study and/or the matrix, can be changed by adding a suitable reagent in ...
