Abstract
Išradimas prikauso medžiagų analizės spektroskopiniams įrenginiams ir gali būti panaudojamas ekologijoje, geochemijoje, medicinoje ir kitur gyvsidabrio garų koncentracijai arba gyvsidabrio kiekiui bandinyje nustatyti.@Išradimo tikslas - matavimų jautrio, tikslumo ir selektyvumo padidinimas, liekamojo efekto sumažinimas.@Išradimo tikslas pasiekiamas tuo, kad naudojami du skirtingi siūlomos konstrukcijos sorbentai, pagaminti iš aukso vielos (diametras 10 cm<d<40cm); be to, naudojama papildoma kaitinimo spiralė, kuria kaitinama dujų magistralė, desorbuojant susikaupusį joje gyvsidabrį ir panaikinant matavimo liekamąjį efektą.@Metodo esmė ta, kad gyvsidabris sukaupiamas iš pradžių "koncentravimo" sorbente, vėliau desorbuojamas ir dujų srautu pernešamas į "analizavimo" sorbentą, vėliau desorbuojamas ir dujų srautu pernešamas į ilgą ploną kiuvetę, kurioje praktiškai visas (>90%) telpa vienu metu ir yra fotometruojamas šviesos sugerties principu.SUMMARY OF THE INVENTION The invention relates to increasing sensitivity, accuracy and selectivity of measurements, reduction of residual effect. two different sorbents of the proposed design made of gold wire (diameter 10 cm <d <40cm); In addition, an additional heating coil is used to heat the gas line by desorbing the mercury accumulated therein and eliminating the residual effect of the measurement. The essence of the method is that the mercury is initially accumulated in the "concentration" sorbent, subsequently desorbed and transferred to the "analyte" sorbent by a gas stream. subsequently desorbed and transferred to a long thin cell with a gas stream, where practically all (> 90%) fits at the same time and is photometric in light absorption.
