The invention discloses a method for simultaneous rapid detection of various sugars, sugar alcohols and alcohols in beer, belonging to the technical field of analytical chemistry. In the method provided by the invention, an integrated pulsed amperometric-ion chromatography is used, by optimization of a pretreatment detection method, experimental factors influencing separation of constituents are researched, and a method for simultaneously detecting 23 types of sugars, sugar alcohols and alcohols (2, 3-butanediol, ethyl alcohol, methanol, glycerin, erythritol, xylitol, fucose, arabitol, sorbitol, trehalose, ribovitol, mannitol, 2-DNA-D-glucose, mannose, melibiose, glucose, maltitol, fructose, lactose, ribose, sucrose, raffinose and maltitol ) in the beer is built one time. Thus, a technicalproblem of accurate analysis on multiple constituents including the sugars, the sugar alcohols and the alcohols in the beer is solved, the method provided by the invention is rapid, accurate and sensitive, realizes simultaneous analysis of multiple types and multiple constituents, and makes an important contribution to detection of beer constituents.
