Flame Photometric Analysis of Sodium in Lithium Carbonate Using Wavelength Shift Function of AA-7800

User Benefits

- Content of sodium in lithium carbonate can be easily analyzed. - By using the wavelength shift function to specify two analysis wavelengths, the background can be corrected even for flame emission spectrophotometry.

Introduction

Lithium carbonate acts on the central nervous system to suppress heightened emotions and has been shown to have beneficial effects, such as mood stabilization and depression reduction. The Japanese Pharmacopoeia specifies evaluation methods for lithium carbonate, including identification, purity evaluation, and quantification methods. In this article, sodium in lithium carbonate was analyzed using an AA-7800 atomic absorption spectrophotometer, in accordance with the 18^th edition of the Japanese Pharmacopoeia. The following is a measurement example of using background correction with the AA-7800 wavelength shift function.
