Push rod for aas samples - manipulates solids into graphite - holder of atomic absorption spectrometer

摘要

Solids can be introduced to the centre of graphite tubes of flameless atomic absorption spectrometers by a push rod moving in a retainer which fit into a conical recess of spark discharge electrode. - The push rod has collars which limit its stroke to half the graphite tube length and has stops to define a 180 degrees turn for emptying its contents.
