Description
ガスサンプルの波長可変ダイオードレーザ分光分析は知られている(例えば、米国特許第6,615,142号参照)。‘142号特許の方法は、サンプルスペクトルがその純粋な成分の一次結合として適合され得るという仮定を伴う計算に依存している。しかしながら、対象成分の濃度がサンプルマトリクス中で比較的低いと、例えば、‘142号特許の計算は、対象成分の濃度を正確に決定することができない。例えば、サンプルマトリクスがエチレンクラッカアセチレン水素化器からのガス流であり且つサンプル中の分析されるべき成分が約100万分の1の濃度のアセチレンである場合、‘142号特許の計算は、比較的低濃度のアセチレンの濃度を正確に見積もることができない。従来技術の前述した問題を解決した波長可変ダイオードレーザに基づく分光法を見出すことができれば、当分野における進展となる。
(1)8ppmのアセチレン;920ppmのメチルアセチレン;40パーセントのエチレン;
(2)1.5ppmのアセチレン;890ppmのメチルアセチレン;39パーセントのエチレン;
(3)1.5ppmのアセチレン;5070ppmのメチルアセチレン;40パーセントのエチレン。
(1)8ppmのアセチレン;1000ppmのメチルアセチレン;40パーセントのエチレン;
(2)1.5ppmのアセチレン;990ppmのメチルアセチレン;40パーセントのエチレン;
(3)1.5ppmのアセチレン;5140ppmのメチルアセチレン;40パーセントのエチレン。
結論として、容易に明らかなように、本発明をその好ましい実施形態に関して説明してきたが、本発明が限定されるものではなく以下の請求項により規定される本発明の範囲内に含まれる全ての代替的手段、改良、等化物を網羅しようとするものであることは言うまでもない。
