[0089] Sample 1:
[0090]
[0091] (4-sulfamoylphenylamino)sodium methanesulfonate is gasified by the gas ionizer and then subjected to high-frequency discharge to ionize the sample gas to generate positive ions in a low charge state; then in the high-frequency electric field of the gas ionizer, the charged The ions collide with the sample atoms and molecules, ionize the sample molecules, and the charged particles multiply to form an infinite discharge, generating a large number of sample charged ions;
[0092] Then the positive booster and the negative booster contained in the ion current generator 2 cooperate to produce positive and negative ions with different charge ratios, and then the ion current generator transmits the positive and negative ions produced to the ion current concentrator through the ion current conduit; The flow concentrator accepts the ion flow from the gas ionizer and the ion flow generator, and then transmits the collected ion flow to the particle m...

Description
technical field [0001] The invention relates to a sample detection analyzer and method, in particular to a sample detection analyzer and method for nuclear magnetic analysis. Background technique [0002] The principle of sample detection and analysis for nuclear magnetic analysis is based on the physical process of atomic nuclei with a non-zero magnetic moment, Zeeman splitting of the spin level under the action of an external magnetic field, and resonant absorption of radio frequency radiation of a certain frequency. NMR analysis is a branch of spectroscopy, its resonance frequency is in the radio frequency band, and the corresponding transition is the transition of nuclear spin on the nuclear Zeeman energy level. The nuclear magnetic analysis technology used today often adopts CW-NMR analysis technology. Although this technical solution is low in price, high in temperature, and easy to operate, it has poor sensitivity, requires a large amount of sample, and can only measu...
