Abstract

Inventia se refera la un dispozitiv pentru densiometrie adaptabil la un spectrofotometru de absorbtie si/sau emisie în vederea baleiajului unor probe microanalitice, cu aplicatii, în special în domeniul biomedical. Dispozitivul, conform inventiei, este constituit dintr-un subansamblu montat în compartimentul pentru cuve al unui spectrofotometru, ambele fiind interfatate la un calculator de procese, subansamblul fiind constituit dintr-o placa de baza pe care este montat un suport cu o fanta pentru fasciculul incident si cu o piesa terminata printr-un capat prismatic pentru dirijarea luminii pe o suprafata superioara a unui echipaj mobil, lumina reflectata difuz sau de fluorescenta fiind apoi dirijata fie tot pe directia fasciculului initial prin reflexia pe o alta fata externa a capatului prismatic, fie prin reflexie la un unghi drept fata de directia initiala a fasciculului incident pe o fata înclinata a unei lamele, proba putînd fi montata vertical pe o rama basculanta în jurul unui ax sau orizontal, pe echipajul mobil a carui translatie este asigurata de o curea de transmisie solidarizata prin întindere între role de echipajul mobil în sicanele acestuia, prin antrenarea frictionala pe axul unui motor pas-cu-pas cu ajutorul unei role presoare, sensul de rotire si numarul de pasi ai motorului fiind programate prin calculator. The invention relates to a device for densitometry adaptable to an absorption and / or emission spectrophotometer for scanning microanalytical samples, with applications, especially in the biomedical field. The device according to the invention consists of a subassembly mounted in the cuvette compartment of a spectrophotometer, both of which are interfaced to a process calculator, the subassembly being constituted by a base plate on which is mounted a support with a slot for the incident beam and with a piece terminated by a prismatic end for directing light on a superior surface of a mobile creature, diffuse reflected light or fluorescence is then conducted either in the direction of the initial beam by reflection on another external face of the prismatic end, reflection at a right angle to the initial direction of the incident beam on a sloping face of a blade, the sample being mounted vertically on a tilting frame around an axle or horizontally on the mobile crew whose translation is provided by a solidarized transmission belt by stretching between the rollers of the mobile crew in its sockets, by frictional training on the axis of a step-by-step motor by means of a pushing roller, the direction of rotation and the number of steps of the engine being programmed by computer.
