Instructions for graphite sleeve

There are two types of graphite tubes - standard high density graphite tubes and pyrolytic coated graphite tubes. The two ends of the standard graphite tube are carved with grooves; The graphite tube is suitable for both aqueous and organic solutions. The inner surface is composed of many fine grooves, which are used to retain the test liquid. The permitted volume of test liquid for aqueous solution and organic solvent is about 125uL and 50uL, respectively. The graphite furnace produced recently can be used with pyrolytic coated graphite tubes. The graphite tube provides analytical advantages, particularly in terms of tube life and sensitivity to some refractory elements such as B, U, V, Ti, Mo, etc. However, pyrolytic coated graphite tubes have little advantage when measuring volatile elements (Cd, Pb, Tl) or when measuring samples containing a matrix.
