Antioxidants Shimadzu Liquid Chromatograph Product Lineup

Ingredients in foods form oxides when exposed to atmospheric oxygen, resulting in quality deterioration. Various food additives are Model Features
used to prevent this oxidation. Four types of phenolic antioxidants are allowed to be added to foods in Japan. These are BHT
(butylated hydroxytoluene), BHA (butylated hydroxyanisole), NDGA (nordihydroguaiaretic acid), and PG (propyl gallate). They are · Multiple solvent delivery options, a broad range of flows, and isocratic or gradient elution
permitted for use in oils and fats, butter, frozen seafood, and dried seafood products. · Numerous detector options to cover a range of sample chemistries
Shown here is an example of the analysis of nine phenolic antioxidants: the four permitted in Japan plus another five that are · Expandable valving options from simple to complex flow paths
permitted for use in other countries. · Covering a broad range of analyses from analytical to semi-preparative, reversed phase, normal phase,
Gel Permeation Chromatography (GPC) and Ion Chromatography (IC)
