我們架設可於實驗室環境下進行低磁場核磁共振量測之系統，此系統之特點為不需將系統放置於屏蔽環境即可量測。然而在磁共振實驗中樣品之磁化量隨著預極化場之磁場大小增加而增加，因此在實驗中以0.75 Tesla之釹鐵硼磁鐵做為預極化場，使樣品之磁化量增加，並利用前級放大器將法拉第線圈所接收到之磁共振訊號放大以利於傳輸。又因環境之磁場值會隨時間變化，使得磁共振之共振頻率也隨之改變，為使訊雜比能經由平均而增加，我們採用時域頻率調整平均(Time-domain Frequency Adjusted Averaging, TFAA)提升磁共振頻譜之雜訊比。此外，在低磁場核磁共振中無法顯現化學位移之特性，使得j-coupling訊號能從中辨識，有助於分析分子之幾何結構。
