In this study, the sensitivity for selenium is reported to depend heavily on the nature of the graphite surface; sensitivities obtained by using a nonpyrolytic graphite tube are higher than those obtained by using a pyrolytic graphite tube; and the volatilization loss of selenium in the charring process is less critical for the nonpyrolytic graphite tube. Furthermore, it is reported that the use of a graphite cloth ribbon placed inside the graphite tube causes a large contact area with analytes and greatly enhances the sensitivity in selenium atomic absorption signals.
