Description

よって、計量分配用気体の高純度を達成するには、吸着剤上に残余の異質可吸着体が残っている場合、加熱作業の温度が重量減少変化ゼロになる時点を大幅に超えることを確保することが重要である。最初の重量減少(100℃までの温度)及びその後の温度上昇に伴う不変(600℃まで)に基づき、吸着剤からすべての異質可吸着体が除去されたと推測可能であるが、それにもかかわらず、吸着剤から残余の異質可吸着体を除去するために、十分な時間と範囲において650℃を超えて加熱し続けることによって計量分配用気体の純度は顕著に向上する。

Claims (15)

  1. (i)可吸着計量分配用気体及び(ii)異質可吸着体に対する吸着親和性を有し、かつ、異質可吸着体が吸着している物理的炭素吸着剤の処理工程であって、前記物理的炭素吸着剤に接触させて非可吸着気体を流しながら前記物理的炭素吸着剤を650℃超の温度まで加熱して、前記物理的炭素吸着剤から前記異質可吸着体の少なくとも一部を脱着する処理工程と、
