Stochiometric Analysis for Glass & Ceramics in IMDS


Free Webinar Event!

 

Register now for our new webinar in Chemical Management, "How to Properly Report Glass and Ceramic Materials in IMDS Using the Stochiometric Analysis Process".

 

On March 11, 2021 from 3:30-4:30pm EST learn about representing glasses, ceramics, and enamels in IMDS and the complex analysis required to do so properly.

 

Heidi Wittenborn, Senior Environmental Consultant with RSJ Technical Consulting, brings 10 years of IMDS experience to the table.  She will be discussing the changes in reporting glass, ceramic and enamel materials and how to use the stochiometric analysis to convert a list of ingredients - to the end state material, while still tracking any declarable substances on GADSL. For IMDS purposes, a stochiometric analysis is a breakdown of the percentages of individual elements present in the substances that make up a material.  Many of these materials are still reported as a list of oxides.  Since these materials are considered UVCB materials under REACH, IMDS developed a way to track declarable content while still reporting appropriately for UVCB materials.

 

Here's the definition and an example. 

 

For IMDS purposes a stochiometric analysis is a breakdown of the percentages of individual elements present in the substances that make up a material.  For example, H2O (water), breaks down into two atoms of hydrogen and one of oxygen.  Hydrogen and oxygen have different atomic weights: hydrogen’s is 1.00784 and oxygen’s is 15.999.

 

Total atomic weight of H2O is (2 x 1.00784) + (1 x 15.99) = 18.0568

Percentage of oxygen in H2O = 15.99 / 18.0568 = 88.55389659297328%

Percentage of hydrogen in H2O = (2 x 1.00784) / 18.0568 = 11.16299676576138%

We can round these numbers in our final accounting of 100% of the substance.

 

The presentation starting at 3:30pm EST will be last approximately 45 minutes followed by time for Q&A.
