Fluorescence Discrimination Analysis of Powdered Beverages Using Reflection-Type Fiber

Introduction

Because the Shimadzu RF-6000 spectrofluorophotometer features a large sample compartment with high expandability, many samples that produce fluorescence, including glass, plastics, and fruits, can be measured by placing the sample in the sample compartment. It is also possible to measure samples that are larger than the sample compartment or cannot be moved to the sample compartment by using a reflection-type fiber measurement unit.*1 Although powder samples generally require pretreatment such as fixing the sample prior to measurement, pretreatment is not necessary when a reflection-type fiber unit is used. This article introduces measurement of powdered beverages using a reflection-type fiber measurement unit.
