You are analyzing the sugars in wine using HPLC. you can use any of the following detectors except UV b) refractive index c) evaporative light scattering d) electrochemical e) MS
UV detectors are not used because of low wavelength range.
The best and convenient method for detecting the sugars is by using ELSD ( evaporative light scattering detector)
This method is sensitive, simple and reliable.
The comparability is found with gradient elution.
Although refractive index detector can also be used for analysing sugars but the best one with more advantages is using ELSD.
Thus, option C is correct.
Hope this helps you.
Thanks

16) Ethanol, CHsO, is produced by the fermentation of sugars in wine and beer. Given that ethanol has a molecular weight of 46.07 g/mol and a density of 0.789 g/em answer the following questions: a) How many mL of ethanol are consumed in a 12 oz. glass of red wine that contains 13.4 % ABV? Note: ABV stands for alcohol (ethanol) by volume. You must use the following conversion factors in your calculation: 128 oz- 1 gal; 1 gal 3.785...
You have just started working at large wine distribution company and have been tasked with analyzing how the company should be pricing their bottles of wine. You have data on a number of different wines that include very detailed reviews, the country of origin, the wine’s rating and designation, and the price that is has been sold at in the past. You hypothesize that higher rated wines should sell for a higher price (duhhh), but want to figure out how...
