1. A method for chemically analyzing a sample using an apparatus including a test piece table, a sample applying station having a plurality of applying holes arranged at specified intervals, a reagent layer constant temperature chamber, a measuring station, said sample applying station having a sample applying nozzle, movable hole covers, and a rod for opening and closing said covers, comprising the steps:

  • positioning a test piece on said test piece table, said test piece including a plurality of reagent layers;

    moving said test piece table to locate each said reagent layer beneath a respective one of said applying holes;

    applying from above a portion of said sample to each said reagent layer in sequence, said sample portion being applied through the associated applying hole by said applying nozzle;

    covering each said hole with a respective one of said covers in sequence after said sample portion is applied, each said cover having a cover piece and a moving piece joined at a connection into an L-shaped, a cover supporting shaft being fitted along said connection, said step of covering comprising moving said rod for opening and closing to pivot said covers about said shaft in sequence with application of said sample portions, said step of applying sample portions being effected by moving said sample applying nozzle over each said applying hole in sequence;

    moving said testpiece table to said measuring station; and

    measuring said sample on said test piece.
