Abstract

Inventia se refera la un procedeu si dispozitiv pentru obtinerea placilor cromatografice, ce consta în aceea ca reglarea grosimii primului strat de suspensii se face la 10...100 mm, a celui de-al doilea la 10 mm, iar sedimentul final se supune sedimentarii fractionate repetate într-o solutie cu pH bine definit, aplicând un raport gel umed - solutie între 1:2 si 1:10, grosimea stratului fiind reglata ca mai sus între 5 si 100 mm, în functie de fractiunea granulometrica urmarita, gelul fractionat umed fiind dozat în sarje cu apa în raport 1:1,8:...1:2,5 fata de gelul uscat cu carbonat de calciu precipitat, carbonat de magneziu esteri fosforici sau alte ongrediente în proportie de 1...15% fata de gelul uscat, sarja fiind omogenizata un timp optim, dupa care se întinde mecanic semiautomat pe placi de sticla, cu sau fara liant. Dispozitivul pentru obtinerea placilor cromatografice este constituit dintr-un suport plan orizontal, pe care se aseaza placile din sticla care urmeaza sa fie acoperite cu un strat de gel de silice., întinderea suspensiei de adsorbant fiind realizata cu un cadru plan distantat corespunzator fata de placile de sticla, cadrul fiind deplasat semiautomat sub actiunea de cadere a unei greutati care se deplaseaza vertical, ghidat într-un amortizor hidraulic, transmisia de forta între greutatea de actionare si cadrul de întindere a stratului fiind realizata cu un cablu flexibil si scripeti.The invention relates to a process and apparatus for obtaining the chromatographic plates, which consists in adjusting the thickness of the first layer of suspensions to 10 ... 100 mm, the second to 10 mm, and the final sediment being subjected to sedimentation repeatedly fractionated in a well-defined pH solution, applying a wet gel ratio of between 1: 2 and 1:10, the thickness of the layer being adjusted as above between 5 and 100 mm, depending on the particle size to be studied, the wet fractioned gel being dosed in water batch at a ratio of 1: 1.8: 1: 2.5 to the dry gel with precipitated calcium carbonate, magnesium carbonate, phosphorus esters or other ingredients in a proportion of 1 ... 15% front by the dry gel, the batch being homogenized for an optimal time, then mechanically stretching semi-automatically onto glass sheets, with or without binder. The device for obtaining the chromatographic plates consists of a horizontal planar support, on which are placed the glass plates to be coated with a layer of silica gel, the stretching of the adsorbent suspension being made with a plane frame spaced correspondingly from the plates the frame being shifted semiautomatically under the action of falling a vertical weight guided in a hydraulic damper, the power transmission between the weight of the drive and the stretch of the layer being made with a flexible cable and pulleys.
