Description

Vynález sa týká zariadenia na rovnoměrné ožarovanie skúmaviek, spektroskopických kyviet a filmov.The invention relates to a device for uniformly irradiating tubes, spectroscopic cuvettes and films.

Doteraz používané ožarovacie zariadenia uplatňujú statické usporiadanie zdroja a ožarovaných skúmaviek, kyviet a filmov, umiestnených v rovině. Pri týchto zariadeniach sa vyžaduje velká geometrická přesnost vyhotovenia. Přitom možno' ožarovať len jednu alebo dve vzorky, čím sa vefmi predlžuje čas, potřebný na vykonanie série meraní.The irradiation devices used hitherto apply a static arrangement of the source and the irradiated tubes, cuvettes and films placed in the plane. These devices require high geometrical accuracy. In this case, only one or two samples can be irradiated, which greatly extends the time required to perform a series of measurements.

Uvedené nedostatky odstraňuje zariadenie na rovnoměrné ožarovanie skúmaviek, spektroskopických kyviet a filmov, pozostávajúcich z nosiča kruhové prierezu alebo nosiča prierezu pravidelného mnohouholníka, na obvode ktorých sú vytvořené otvory pre skúmavky, držlaky pre kyvety a rámčeky pre filmy podfa vynálezu, ktorého podstata spočívá v tom, že skúmavky, spektroskopické kyvety a rámčeky pre polymérové filmy sú umiestnené v otočných nosičoch, pričom zdroj světla je umieštnený v střede nosiča.The aforementioned drawbacks are eliminated by a device for evenly irradiating tubes, spectroscopic cuvettes and films, consisting of a circular cross-sectional carrier or a regular polygonal cross-sectional carrier, having peripheral openings for tube openings, cuvette holders and film frames according to the invention. 2. The method according to claim 1, wherein the tubes, spectroscopic cuvettes and frames for the polymer films are placed in rotatable carriers, the light source being located in the center of the carrier.

Vynález otočného ožarovacieho zariadenia umožňuje regulovat výšku polohy skúmaviek v otočnom nosiči vhodným výberom vefkosti distančných rúrok a využit různé tvary ožarovacích zdrojov. Vzhfadom na to, že priestor v střede ožarovacieho nosiča je dost velký, možno zdroj viditelného alebo ultrafialového žiarenia umiestniť do jedného alebo viac plášťového reaktora, ktorý zabezpečuje odvod, tepla cirkulováním chladiacej vody a vymedzuje aj šířku ožarovacieho pásma volbou filtračného roztoku.The invention of the rotary irradiation device makes it possible to regulate the height of the tubes in the rotatable carrier by appropriately selecting the size of the spacers and to utilize different shapes of radiation sources. Since the space in the center of the irradiation carrier is large enough, a visible or ultraviolet radiation source can be placed in one or more jacket reactor to provide heat dissipation by circulating cooling water and also limits the irradiation zone by selecting a filter solution.

Zariadenie rovnoměrného ožarovanie skúmaviek, spektroskopických kyviet a filmov je znázorněné na obr. 1 a 2. Na obr. 1 je znázorněné zariadenie s nosičom prierezu pravidelného mnohoúhelníka.A device for uniformly irradiating tubes, spectroscopic cuvettes and films is shown in FIG. 1 and 2. FIG. 1 shows a device with a cross section of a regular polygon.

Na obvode nosiča 1 Sú otvory pre skúmavky 3 a na nosiči 2 držiaky pre kyvety 4 a rámčeky 5 pre filmy. Zariadenie na spektroskopické kyvety a filmy s otočným nosičom 2 s prierezom pravidelného osemuholníka má v střede každé j steny umiesťnený držiak na spektroskopické kyvety 4 v tvare kočky. Před kyvetou 4 je umieštnený vhodný filter pre izoláciu pásma ožarovania. Podfa tvaru kyvety 4 sa volí držiak, ktorý může byť pevný alebo snímatelný. Rovnoměrnost fotochemickej reakcie v roztoku sa zabezpečí miešaním pomocou magnetického miešadla. Rotor otáčania magnetického miešadla může byť umieštnený pre kyvety tvaru kočky v spodnej časti alebo na boku pre kyvety tvaru valca. Spodná časť nosiča je spojená s motorom pomiocou kolektora s dvorná alebo viacerými zberačmi. Ak sa do jednej steny osemstenu připraví přístroj na meranie intenziy žiarenia, možno ďalšie zberače využit na odvod elektrického jprúdu na fyzikálnom principe (napr, fotodióda, kvantový počítač a pod.).On the periphery of the carrier 1 there are holes for the tubes 3 and on the carrier 2 the holders for the cuvettes 4 and the frames 5 for the films. The apparatus for spectroscopic cuvettes and films with a rotating carrier 2 with a regular octagonal cross-section has a cat-shaped holder for spectroscopic cuvettes 4 in the center of each wall. A suitable filter is placed in front of the cuvette 4 to isolate the radiation zone. According to the shape of the cuvette 4, a holder is selected which can be fixed or removable. The uniformity of the photochemical reaction in the solution is ensured by stirring with a magnetic stirrer. The rotor of the magnetic stirrer can be positioned for the cat-shaped cuvettes at the bottom or on the side for the cylindrical cuvettes. The lower part of the carrier is connected to the engine by means of a collector with yard or several collectors. If an instrument for measuring the intensity of radiation is prepared in one wall of an octahedron, other collectors can be used for the dissipation of electric current on a physical principle (eg photodiode, quantum computer, etc.).

Zariadenie na filmy umožňuje ožarovať filmy kruhového tvaru o priemere 4 cm, připadne menšie. V zariadení můžno ožarovať aj filmy připravené na Petriho miske. Jedna poloha sa může upravit tak, ako pre ožarovanie spektroskopických kyviet, čím sa vytvoria podmienky aj pre chemickú aktinometriu (ferioxalátovú alebo uranyloxalátovú), príp. pre fyzikálně meranie intenzity zdroja.The film device allows to irradiate circular films with a diameter of 4 cm, or smaller. Films prepared on a Petri dish can also be irradiated on the device. One position can be adjusted as for the irradiation of the spectroscopic cells, thus creating conditions for chemical actinometry (ferioxalate or uranyloxalate), respectively. for physically measuring the intensity of the source.

Zariadenie možno využit v chemických laboratóriách a skúšohniach.The equipment can be used in chemical laboratories and testing rooms.
