ANALYSIS FOR METALS AND OTHER ELEMENTS
We determine most elements by ICP-AES and/or ICP-MS (see these methods for specific pricing) as well as colorimetric, gravimetric, titrimetric, or other procedures. Please inquire as to the best approach for your specific samples and analytical requirements.
Sample Preparation for Metals Analysis
Solids and often water or wastewater samples require digestion or other sample preparation prior to analysis. Because each matrix type normally requires a minimum of a blank, a duplicate and a reference standard and/or spike to assure quality analysis, there is a minimum preparation and determination charge of five (5) samples per test per matrix. Analysis for metals generally involves introduction of an aqueous solution into our atomic spectroscopy instrumentation.
The result of any analysis is no better than the viability of the sample solution presented to the instrument. Our knowledge and experience in the decomposition and dissolution of a wide variety of materials ranging from oils, polymers, and biological tissues to complex alloys, minerals, and ceramics allows us to provide quantitative results for virtually all sample matrices. If necessary, the sample is dried, ground, and homogenized prior to various acid digestion or high temperature fusion techniques to put the elements of interest into solution. Not all elements can be solubilized and maintained in solution from a single decomposition. Specific matrix and analyte combinations may require two or more different decompositions. By providing us with as much information as possible about your samples at the time of submittal, we are able to choose preparations appropriate for your sample matrix and analyte combinations at minimized time, cost, and consumption of sample material.
