====Capturing the data====
The quartz slide was placed into two stabilisers, which was then installed into the machine. This machine did the laser ablation on the hair samples. Figure 16 displays the quartz slide with the hair samples, installed into the laser ablation system. While Figure 17 displays the enlarged version of the quartz slide on the monitor.

Next to the laser ablation system, there are two monitors which will be used for the laser ablation task. The left monitor records the data of the laser ablation and the right monitor controls the laser ablation system, this can be seen in Figure 18. The next step involved choosing how many spots of the hair we want ablated and the distance between these spots. A spot is where the laser will ablate the hair and the isotopes will be recorded for that spot. It was chosen to ablate the hair about half way (1cm), which gave 11 spots at about 800 micro meters apart, two of these spots were located in the root. The mass spectrometer will then document the chosen isotopes. The complete set up of the experiment is shown in Figure 19, with the laser ablation system on the left and the mass spectrometer on the right.
