DART-MSと昇温デバイスによるブチレングリコールオリゴマーの分析
DART (Direct Analysis in Real Time), a direct atmospheric pressure ionization source, is capable of analyzing chemical materials with little or no sample preparation. In DART analysis, as samples are only introduced into the heated helium gas flow which is set at the preset temperature, they can be analyzed in a quite short time such as about 10 seconds. We had developed the temperature rising device combined with DART-MS system, which could make the heating temperature of sample rise with the passage of time. It became able to acquire a MS spectrum while changing the heating temperature successively by this. Here, we report the analyses of 1,3-butylene glycol oligomer samples using this temperature rising device.
