Preparing NMr Samples of liquids I)Dry and remove all solvent from your compound 2)Take a clean, dry nmr tube and place it in a 10-mL graduated cylinder 3) Place a Kimwipe pipet filter on top of the Nmr tube. This is constructed by taking a small piece of a Kimwipe and stuffing it into a small Pasteur pipet. It can be tamped into place using the tip of a large Pasteur pipet. (This filter will remove any insoluble impurities. 4)Dip the tip of a different pipet into your sample. Capillary action will draw approximately 10 mg of the compound into the pipet 5)Insert this pipet into the pipet filter and rinse the sample into the nMr tube with deuterated solven 6) Check to see that you have enough solvent 7)Cap your NMR tube and record the sample number if running more than one spectrum (Writing on the colored cap is the easiest way to do this. 8)After running the NMR, rinse the sample back into the flask containing your compound and concentrate it to remove the solvent Preparing NM Samples of Solids 1)Perform steps 1-3 above. 2) Place approximately 10 mg of your sample into a vial 3)Dissolve your compound in about 1 mL of deuterated solvent. 4)Using a pipet, transfer the liquid through the pipet filter into the nmr tube 5)Perform steps 6-8 above Cleaning NMR Tubes: I)Rinse the tube thoroughly with acetone 2)Place the tube in a drying oven for about one hour 3)Store the tube in a desiccator at room temperaturePreparing NMR Samples of Liquids: 1) Dry and remove all solvent from your compound. 2) Take a clean, dry NMR tube and place it in a 10-mL graduated cylinder. 3) Place a Kimwipe pipet filter on top of the NMR tube.

(This filter will remove any insoluble impurities.) 4) Dip the tip of a different pipet into your sample. Capillary action will draw approximately 10 mg of the compound into the pipet. 5) Insert this pipet into the pipet filter and rinse the sample into the NMR tube with deuterated solvent. 6) Check to see that you have enough solvent. 7) Cap your NMR tube and record the sample number if running more than one spectrum. (Writing on the colored cap is the easiest way to do this.) 8) After running the NMR, rinse the sample back into the flask containing your compound and concentrate it to remove the solvent. Preparing NMR Samples of Solids: 1) Perform steps 1–3 above. 2) Place approximately 10 mg of your sample into a vial. 3) Dissolve your compound in about 1 mL of deuterated solvent. 4) Using a pipet, transfer the liquid through the pipet filter into the NMR tube. 5) Perform steps 6–8 above. Cleaning NMR Tubes: 1) Rinse the tube thoroughly with acetone. 2) Place the tube in a drying oven for about one hour. 3) Store the tube in a desiccator at room temperature. 45
