Effects of gradient magnetic fields on diffusion process of glycine in water

Abstract

We studied diffusion processes of organic materials in water under gradient magnetic fields. We used two liquid chromatographic systems to observe diffusion processes of glycine and albumin under magnetic fields of up to 8 T. We measured the absorbance of glycine solution from an outlet of the column using low pressure liquid chromatography. The peak intensity in the chromatogram of glycine changed 10%-500% depending on the strength and direction of the magnetic field gradient. The retention time in the chromatogram of glycine was significantly prolonged when the direction of magnetic forces opposed the direction of the flow. We also measured the retention times of glycine and albumin under magnetic fields of up to 8 T using an HPLC system. The retention times of the two solutes under gradient magnetic fields increased by 100%-370%.
