Identification and Comparison

The analysis and comparison of materials are two areas which are intertwined and included in one another.
Analysis means to know the chemical composition of the material that is being examined.
Comparison is the ability to answer the question, “Do two substances have a common material origin (common source)?”

At the Institute of Forensic Science, it is possible to analyze materials even in minuscule quantities. The Institute holds special expertise in the comparison of materials and the assessment of their common origin even in the smallest of quantities.

At the Institute of Forensic Science, we are able to analyze and compare the following:

»  Fluids

»  Pastes

»  Solids

»  Powders

»  Mixtures / Compounds

With the help of analysis and comparison processes carried out at the Institute of Forensic Science, the following questions can be answered:

»  What is the material’s composition? – Materials can be a single compound or a

mixture

»  Is the material contaminated? – Contaminations are undesirable substances which

might origin in production processes or be the result of their addition in the

course of a material’s life span.

»  What is the material’s dedicated application? – It is possible to obtain an

evaluation of the material’s purpose.

» What is the dosage of each of the material’s components? – This question is of

importance for criminal investigations and in cases where the concentration of

each of the components carries a special weight.

» Can two substances share a common origin? – The Institute of Forensic Science

has the unique ability to compare substances and determine the probability

whether substances found in different locations have a single common origin.
