A Mini Test on Separation of Mixtures

I used to think that forensics use chromatography method to test samples of blood as it is the best method among the rest of the other four methods (magnetic attraction, filtration, evaporation, distillation).

But now I think that forensics use the chromatography method to test samples of blood because:

• Small amount of the sample is needed
• The method is able to identify the contents of the sample
• Purity of the sample can also be tested

The test was quite challenging as it tests us on how well we know about the topic (separation of mixtures). The most challenging part was to complete the mind-map.
