To characterize monosaccharide composition of exopolysaccharide by HPLC method I need to hydrolyze EPS with 0.5 M H2SO4 at 95°C for 12 h followed by neutralization with 4 M NaOH. How much sample and how much H2SO4 should I use?
Hello, to be sure that acid enough you can take 1g of exopolysaccharide add 10ml 0.5M Sulfuric acid. Aso you can take attention on hydolysis solution pH after addition of acid which should be not above than 2.0 for better yield.
