Direct Measurement of Minerals (Fe, Zn, Cu, Mn) in Wine Using Flame Atomic Absorption Spectrophotometry

Introduction

Flame atomic absorption spectrophotometers are capable of the direct measurement of samples with a complex matrix and also feature easy operability and maintainability. Although samples normally require digestion by heating prior to measurement, there are cases where samples in liquid form, such as beverages, can be measured directly. This article introduces an example of the direct measurement of minerals, iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn), that are included in a commercially available wine using a flame atomic absorption spectrophotometer.
