- Primary Outcome Measures
Name Time Method Aim of the study is to determine the age of a bloodstain by measuring its absorption spectrum. For this, bloodstains of diffente ages are measured via spectrophotometer. The results are correlated with the age.
- Secondary Outcome Measures
Name Time Method The method shall be validated and established for routine work. It shall be used regularly in forensic work.
