校正結果の応用
CPCユーザは,補正された粒子濃度及びその不確かさに主な関心がある。装置校正の結果は,CPCの濃
度測定値CCPCの関数である補正後濃度Cによって表すことができる。
C (N.1)
CCPC / η
最も基本的な実用例は,プラトー領域のある1粒径,1濃度レベルのエアロゾル粒子を,CPCが単一粒
子計数モードで動作している場合である。不確かさの伝ぱ(播)則を用いて,相対合成標準不確かさuc,r(C)
は,次の式によって計算できる。
uc C
uc,r C ur2 CCPC ur2 η (N.2)
C
対象とする粒径及び濃度でのur(η)の値は,FCAEによる校正を基にした式(10)又は参照CPCによる校正
を基にした式(17)から計算する。CPC濃度測定に対する不確かさの下限値は,通常,ポアソン確率分布に
従うと想定される計数誤差に基づいた不確かさより得ることができる。計数による不確かさは次のように
表される。

ur CCPC (N.3)
CCPCqCPCt
ここで,qCPCはCPCの検出器流量,tはサンプリング時間である。CCPCqCPCtが100以上の場合,式(N.3)
は有効である。図N.1は式(N.3)を可視化したもので,標準不確かさが1 %になる場合,及び測定時間が1
分間の場合に対応する。
1 %の不確かさは,流量1 L/min及び平均化時間10秒の場合,濃度60 cm-3に対応する。
