![[Analysis Case] Quantitative Analysis of Sugars (Monosaccharides to Oligosaccharides) in Soft Drinks](https://image.mono.ipros.com/public/product/image/e16/2000614183/IPROS14280267726197650645.png?w=280&h=280)
It is possible to quantify the target substance! Here are examples of analyses using the HPLC-RID method and the HPLC-ELSD method.
The ultraviolet absorption of sugars (monosaccharides to oligosaccharides) can only be obtained around 190 to 195 nm, making detection difficult. Therefore, methods such as derivatization or using a refractive index detector (RID) or an evaporative light scattering detector (ELSD) are effective for measurement by HPLC. Here, we will introduce a case study analyzing sugars in soft drinks using RID and ELSD. For more details, please refer to the PDF download below.
