Zusammenfassung:The invention relates to a process for manufacturing a small tube for detecting the hydrogen sulphide in an air-hydrogen sulphide mixture or in a mixture of industrial gases. A layer of 74 mm of silica gel RH imbibed with an aqueous solution of lead acetate having a concentration of 1% and mercuric chloride in a concentration of 0.1% is introduced in a glass tube having the length of 120 mm and the diameter of 5 mm. Invenţia se referă la un procedeu de obţinere a unui tubuşor detector de hidrogen sulfurat dintr-un amestec de aer-hidrogen sulfurat sau de gaze industriale. Intr-un tub de sticlă de 120 mm lungime şi 5 mm diametru, se introduce un strat de 74 mm de silicagel RH impregnat cu o soluţie apoasă de acetat de plumb de concentraţie 1% şi clorură mercurică de concentraţie 0,1%.
