Embodiment Construction

[0025] figure 1 The principle of an exemplary apparatus 100 for ionizing particles of a sample gas flow according to a preferred embodiment of the present invention is shown. The device 100 includes an inlet, which may be in the form of a first fluid tube 102 , for providing a sample gas flow 101 . Furthermore, the apparatus comprises a generator 104 for generating reagent primary ions from particles (molecules) of the candidate reagent gas flow 103, preferably in the primary ion generation region 112 (the region in which X-ray ionizing radiation ionizes the candidate reagent gas flow 103) 107.

[0026]The device also has an interaction region 113 for introducing the reagent primary ions 107 into the sample gas flow 101, thereby effecting charge transfer between the primary ions and the particles of the sample gas flow to be determined and thus generating a particle of interest. The sample gas ions 111 are transported to the detector. The interactions are typically ion-mole...

Abstract

A device for ionizing particles (molecules or clusters) of a sample gas flow comprises a first flow tube for providing the sample gas flow, and a generator for producing reagent primary ions from particles of candidate reagent gas flow at a primary ion production region. The device also has an interaction region for introducing the reagent ions into the sample gas flow in order to arrange interaction between the reagent primary ions and the particles of the sample gas flow, thereby producing sample gas ions to be delivered to a detector. The generator for producing reagent primary ions is a non-radioactive soft X-ray radiation source.

Description

technical field [0001] The present invention relates to methods and devices for ionizing particles of a sample gas flow prior to a detector such as a mass spectrometer to determine properties such as mass or concentration of a gas phase sample or in particular molecules or clusters such as gas phase base or acid samples. Background technique [0002] Accurate mass spectrometry methods for determining the properties of gas phase samples are of great importance eg in atmospheric research, such as studying the role of eg different chemicals such as ammonia, amines, sulfuric acid and oxidized organics in the formation of atmospheric nanoparticles. In particular, a better understanding of the low concentrations and variability of amines and highly oxidized organics in the atmosphere, as well as many other bases and acids, is needed. [0003] However, the measurement of trace gaseous compounds, eg from air, is extremely difficult because their concentrations are extremely low comp...
