The Lane-Eynon method is an example of a tritration method of determining the concentration of reducing sugars in a sample. When placed in an oven the water evaporates and a carrier gas usually air or nitrogen dried with a molecular sieve transports the released water into the titration cell where the determination of the water content takes place. This chemical called the titrant or titrating solution reacts with.
