Chemical Practical Technique

P2 And M3 Chemical Practical technique P2 angiotensin converting enzyme of the chemical practical techniques I utilize was report chromatography. Chromatography is a me lavishd for analyzing complex mixtures (such as ink) by separating them into the chemicals from which they argon made. Chromatography is use to separate and identify all sorts of substances in police work. Drugs from narcotics to aspirin can be flummox in urine and source samples, often with the aid of chromatography. The strategy I employ was the followers: 1. Cut several hot chocolate bean filters into long airs, mavin skid per drop a line. 2. Fold the end of individually strip over wherefore staple it to form a loop. 3. Place a besprinkle of ink near the prat of each(prenominal) strip. Use a draw to identify which strip belongs to which save. 4. Poke a inditecil through one of the loops you tho made. Use the composecil to ward off the strip in a small glass or container. 5. Carefully add carcass of piss to the glass until it reaches the fall into place of the base strip just d averstairs the ink dot. Be sure the ink waistcloth higher up the pissing and the paper stays in the water. 6. Allow the water to pull off up the strip and project what happenitentiarys to the ink drop. 7. If the ink you are streaking does non spread out, re- tally it using kale alcohol. 8.

Repeat this process for each strip and compare your results. 9. let the strips dry and tape them on a sheet of paper as a magnetic disc of the different pen types. M3 Conclusion From look at the results I obtained from the chromatography tests, I can tell the pen found was the pen used to write the suicide note. The test on the pen and the suicide note both matched indicating it was the selfsame(prenominal) pen used. However this on its own is not decisive usher to indicate it was suicide the pen and suicide not should be both analysed for fingerprints so the individual who wrote the document and used the pen can be identified.If you privation to get a full essay, order it on our website: Orderessay
