Description
Vynález sa týká kontinuálneho miešaoieho a pridávacieho zariadenia k spektrofotometrem na pridávanie a odsávánie médií a látok z kyvety.The invention relates to a continuous mixing and adding device for spectrophotometers for adding and aspirating media and substances from a cuvette.
Doteraz používané spektrofotometrické přístroje umožňujú sledovat? priebeh reakcii spojených so změnou v absorbcii světla a změny, ktoré prebiehajú po přidaní určitých látok počas reakcii, príp· zabezpečujú miešanie reakčných zmesi počas spektrofotometrickej analýzy. Napr· pri stopped ilow accessory zariadeníach sa pneumaticky dopravuje médium a analyzovaný materiál do spektrofotometrickej kyvety, kde sa od času zmiešania sleduje priebeh reakcie. Miešacie a pridávacie zariadenie umožňuje kontinuálno přemiešavanie vzorky v spektrofotometrickej kývete a zároveň pneumatické pridávanie látok k analyzovanej vzorke· Pri miešacom zariadení s miesacím diskom možno připravit’ látku, ktorej reakciu so vzorkou v spektrofotometrickej kývete chceme sledovat? a počas premiešavania vzorky sa připravená látka přidává k analyzovanej vzorke· Uvedené zariadenia móžu v mnohých prípadoch uspokojit nároky experimentátora alebo spektrofotometrického laboratória Častokrát je potřebné podrobné sledovat? priebeh reakcii, pričom súčasne dostupné zariadenia neumožňujú plné využiť možnosti modernej spektrofotometrickej techniky· Je to najmá preto, že nie všetky umožňujú sledovat reakcie látok v kývete od počiatku jej ovplyvňovania. Okrem toho nezabezpečujú premiešavanie látok počas reakcie a neumožňujú přidávat do reagujúcej zmesi látky, ktorými chceme reakciu ovplyvniť. Nutnost vyberania zariadenia a kyvety zo spektrofotometrického prístroja k očisteniu a príprave nového merania predlžuje dlžku merania.Previously used spectrophotometric instruments allow to monitor? the course of the reactions associated with the change in light absorption and the changes occurring after the addition of certain substances during the reaction, respectively, ensures the stirring of the reaction mixtures during spectrophotometric analysis. For example, in stopped ilow accessory devices, the medium and the analyzed material are pneumatically conveyed to a spectrophotometric cuvette, where the progress of the reaction is monitored from the time of mixing. The mixing and addition device allows for continuous mixing of the sample in the spectrophotometric rocker and at the same time pneumatic addition of the substances to the sample to be analyzed. and while the sample is being mixed, the prepared substance is added to the sample to be analyzed · In many cases, these devices can satisfy the demands of an experimenter or a spectrophotometric laboratory. the course of reactions, while the currently available devices do not allow the full use of the possibilities of modern spectrophotometric techniques. In addition, they do not ensure the mixing of the substances during the reaction and do not allow the addition of substances to be reacted to the reaction mixture. The necessity to remove the device and the cuvette from the spectrophotometric instrument to clean and prepare a new measurement extends the measurement time.
Uvedené nedostatky odstraňuje kontinuálně miešacie a pridávacie zariadenie k spektrofotometrom podl’a vynálezu,These drawbacks are eliminated continuously by the mixing and adding device to the spectrophotometers of the invention,
