Certified Reference Materials for Microanal]ftical Methods 

Microchemistiy - a branch of analytical chemistry that involves procedures that require handling of very small quantities of materials. Specifically it refers to carrying out various chemical operations (weighing, purification, quantitative and qualitative analysis) on samples ranging from 0.1 to 10 milligrams. (The Condensed Chemical Dictionary 1971). 

To further clarify the scope of our discussion, we present a compilation of existing and developing modem microanalytical techniques in Table 4.3. These techniques routinely use small samples in the aforementioned mass range, with some techniques extending their capabilities to significantly smaller sample sizes.
