The partial replacement of YS/T 226.3-1994 "selenium Determination of tin content Phenylfluorone - bromo cetyltrimethylammonium absorptiometry" YS/T 226.6-1994 "selenium arsenic content determination of arsenic molybdenum blue spectrophotometric method", YS/T 226.8-1994 "selenium in determining the amount of boron times Methylene blue photometric method "and YS/T 226.13-1994" selenium and tellurium in determining the amount of oscillopolarographic law. " And YS/T 226.3-1994, YS/T 226.6-1994, YS/T 226.8-1994 and YS/T 226.13-1994 compared, this section there are major changes as follows.

--- Using the ICP-MS method for the determination.

--- Expand the scope of determination of elements, including silver, aluminum, arsenic, boron, mercury, bismuth, copper, cadmium, iron, gallium, indium, magnesium, nickel, lead, silicon, antimony, tin, tellurium, titanium, the amount of zinc and the like.
