Title:
【発明の名称】入口システム、分離管そして減圧手段を有するガスクロマトグラフ装置
Document Type and Number:
Japanese Patent JP2002534680
Kind Code:
A
Abstract:
A gas chromatographic device has an inlet system, a column and a pressure reducing means combined and assembled in such a series arrangement that provides adequate system performance with shorter wide bore column length and shorter sample analysis times needed during a peak integration and evaluation process performed by a connected mass spectrometer system. Pressure reducing means may be integral part of the inlet system or the column when positioned between the inlet system and the column. Pressure reducing means preferably positioned before the column and being capable of reducing the pressure prevailing at the inlet of said pressure reducing means to a column outlet pressure which is essentially vacuum. Preferably, the inlet pressure of the device is in a range between 10 kPa and 1000 kPa and the absolute pressure prevailing at the outlet of said pressure reducing means is in a range between 0.00001 kPa and 50 kPa.
