概要
- 論文の詳細を見る
A multi-function Curie-point direct injection probe to be coupled to a mass spectrometer was developed. The probe can be used for pyrolysis, chemical reactions and trap-and-purge analysis. In this paper, two injection methods are described, one involves methylation and the other involves trap-and-purge in the probe.Terephthalate was methylated by tetramethylammonium hydroxide and injected simultaneously by Curie-point heating at 500°C for 3 sec.The trap-and-purge method was used to inject a low molecular weight substances, such as HPLC fractions and concentrated atmospheric hydrocarbons. This probe provided a new way to identify polar, volatile, and HPLC samples without pretreatment.
