Предложены способ и устройство для проведения экспресс-анализа на присутствие, например, в пробах почв или горных пород. Способ включает контактирование золотосодержащего раствора с окислителем и по меньшей мере с одним краунэфиром, затем отделение комплексного соединения золота с краунэфиром от оставшихся компонентов раствора, извлечение ионов золота из комплексного соединения золота с краунэфиром, затем контактирование полученного золотосодержащего раствора с индикаторными средствами, например хромофорами, и затем измерение количества связанных индикаторных средств в растворе. Устройство содержит оптический источник, который облучает комплексное соединение пробы падающим излучением с первой длиной волны, детектор, который обнаруживает флуоресцирующий свет со второй длиной волны, детектор, который обнаруживает проходящий свет с первой длиной волны, детектор для обнаружения интенсивности источника излучения. Процессор корректирует обнаруженный флуоресцирующий и пропущенный свет при изменении интенсивности падающего излучения и отдельно определяет концентрацию золота на основе соответственного корректированного флуоресцирующего и пропущенного света и выбирает, какое из двух измерений представляет наиболее точную меру концентрации золота.The proposed method and device for rapid analysis of the presence, for example, in samples of soil or rock. The method involves contacting the gold-containing solution with an oxidizing agent and at least one crown ether, then separating the gold complex with the crown ether from the remaining components of the solution, extracting gold ions from the gold complex with the crown ether, then contacting the resulting gold-containing solution with indicator agents, for example chromophores, and then measuring the amount of associated tracer in solution. The device contains an optical source that irradiates the complex compound of the sample with incident radiation of the first wavelength, a detector that detects fluorescent light of the second wavelength, a detector that detects transmitted light of the first wavelength, a detector for detecting the intensity of the radiation source. The processor corrects the detected fluorescent and transmitted light when the intensity of the incident radiation changes, and determines the gold concentration separately based on the corresponding corrected fluorescent and transmitted light and selects which of the two measurements represents the most accurate measure of gold concentration.
