Abstract:
(EN) A column protection gas supply path (4) is connected to a carrier gas flow path (17) between a sample vaporization chamber (12) and an MS unit (2). During standby, providing column protection gas via the column protection gas supply path (4) makes it possible to protect a column (11) on the side downstream from the confluence (16) of the column protection gas supply path (4) and the carrier gas flow path (17). At that time, carrier gas remains in the carrier gas flow path (17) on the side upstream (16) from the confluence (16). Therefore, when analysis is started thereafter and carrier gas is supplied, there is already a certain level of carrier gas in the flow path (17). As a result, because the time required for completely converting the gas in the flow path (17) from column protection gas to carrier gas is reduced, the waiting time until the start of analysis can be reduced.
(FR) Un trajet d'alimentation en gaz de protection de colonne (4) est raccordé à un trajet d'écoulement de gaz vecteur (17) entre une chambre de vaporisation d'échantillon (12) et une unité de SM (2). En mode veille, l'introduction d'un gaz de protection de colonne par l'intermédiaire du trajet d'alimentation en gaz de protection de colonne (4) permet de protéger une colonne (11) du côté aval par rapport à la confluence (16) du trajet d'alimentation en gaz de protection de colonne (4) et du trajet d'écoulement de gaz vecteur (17). A ce moment, le gaz vecteur reste dans le trajet d'écoulement de gaz vecteur (17) du côté amont (16) par rapport à la confluence (16). Par conséquent, quand une analyse est initiée par la suite et que le gaz vecteur est introduit, un certain niveau de gaz vecteur se trouve déjà dans le trajet d'écoulement (17). Par conséquent, comme le temps nécessaire pour remplacer totalement le gaz se trouvant dans le trajet d'écoulement (17), qui est le gaz de protection de colonne, par le gaz vecteur est réduit, le temps d'attente jusqu'au début de l'analyse peut être réduit.
(JA)  試料気化室12及びMS部2の間におけるキャリアガスの流路17にカラム保護ガス供給路4を接続する。待機中は、カラム保護ガス供給路4を介してカラム保護ガスを供給することにより、カラム保護ガス供給路4とキャリアガスの流路17との合流部16よりも下流側においてカラム11を保護することができる。このとき、合流部16よりも上流側におけるキャリアガスの流路17には、キャリアガスが残ったままの状態となる。したがって、その後に分析を開始する際にキャリアガスが供給されたときには、既にある程度のキャリアガスが流路17内に存在している。これにより、流路17内のガスをカラム保護ガスからキャリアガスへと完全に置換するための時間が短くなるため、分析開始までの待機時間を短縮することができる。
