| Summary: | This study focused on the acquisition of a free precession signal of the different aqueous solution and analyzed their corresponding Proton Spin Lattice Relaxation times. To monitor the free precession signal at 30 50 ms with a frequency of about 2,400 Hz & Explorer GLX PASCO digital acquisition device was used to acquire real-time measurements to be stored and analyzed using the Data Studio Computing platform. From the acquired image, the maximum amplitude of the free precession signal was obtained to derive the magnetization graph and obtain its slope that will be used in to derive the Proton Spin lattice Relaxation time. Using the Past Power Analysis of the Explorer, the study was able to determine the precession frequency which is between 2476 to 2786 Hz which is within the indicated precession frequency. Results show that the free precession signal of the different aqueous solutions has a background noise caused by electrical devices within the vicinity of experimentation. The derived Proton Spin Lattice Relaxation times for Ethanol is 3.98831s, Methanol is 2.90195s, Acetone is 12.34568s, Distilled water is 6.435006s and Tap water is 3.892565s. |
