Abstract
Изобретение относитс к технике анализа жидких веществ и может быть использовано в приборостроении при производстве масс-спектрометров дл анализа сложных многокомпонентных смесей. Цель изобретени - повышение точности и экспрессности анализа. Способ осуществл етс следующим образом. Образец вводитс микрошприцом в камеру испарени 2, расположенную внутри баллона 3, обогреваемого контейнером 4. При испарении образца его пары смешиваютс с инертным газом - носителем, подаваемым под давлением (1,05-1,1).105 Па. Образующа парогазова смесь вводитс через капилл р 5 в ионизационную камеру масс-спектрометра. 1 ил.The invention relates to a technique for analyzing liquid substances and can be used in instrumentation in the manufacture of mass spectrometers for the analysis of complex multicomponent mixtures. The purpose of the invention is to improve the accuracy and expressness of the analysis. The method is carried out as follows. The sample is introduced by a microsyringe into the evaporation chamber 2 located inside the cylinder 3 heated by the container 4. When the sample evaporates, the vapors are mixed with an inert carrier gas supplied under pressure (1.05-1.1) . 10 5 Pa. The resulting vapor-gas mixture is introduced through the capillary tube 5 into the ionization chamber of the mass spectrometer. 1 il.
Description
Таким образом, предлагаемый способ сшгаает погрешность определени в 2 раза.Thus, the proposed method skews the determination error by 2 times.
Использование предлагаемого способа ввода позвол ет снизить объем жидкой пробы, требуемой дл анализа, до 10 мкл (дл прибора с чувствительностью пор дка г).Using the proposed input method allows to reduce the volume of liquid sample required for analysis to 10 µL (for an instrument with a sensitivity of the order of g).
Малый объем пробы, высокие температуры и система посто нного протока газа устран ют адсорбционные эффекты , и прибор через несколько минут после ввода пробы в испаритель может быть использован дл следующего анализа. В результате повышаетс точность определени состава образца, CHH жаетс трудоемкость эксперимента и сокA small sample volume, high temperatures, and a constant gas flow system eliminate the adsorption effects, and the device can be used for the next analysis a few minutes after the sample is introduced into the evaporator. As a result, the accuracy of determining the composition of the sample is increased, CHH is compressed experimentally and juice
