Test system for the determination of substances in test fluids and process for the preparation thereof |
| abstract |
A TEST SYSTEM AND DEVICE FOR THE DETERMINATION OF SUBSTANCES IN TEST FLUIDS WHICH UTILIZES A NOVEL CELLULOSE DERIVATIVE MEMBRANE IN CONJUNCTION WITH A TEST REAGENT SPECIFICALLY REACTABLE WITH THE SUBSTANCE BEING DETECTED AND SENSING MEANS FOR DETECTING ELECTRICAL, CHEMICAL OR PHYSICAL CHANGES IN THE MEMBRANE WHEN THE TEST REAGENT CONTACTS THE SUBSTANCE BEING DETECTED. THE MEMBRANE IS PREPARED USING A CONTROLLED ORGANIC PHASE EVAPORATION: AQUEOUS INVERSION PROCESS FROM A SOLVENT SOLUTION OF POLYMERIC CELLULOSE DERIVATIVE AND AN INTERACTING SWELLING AGENT, PREFERABLY FORMAMIDE, SAID REAGENT CONTAINED IN SAID SOLUTION AND THE RESULTING MEMBRANE IN EITHER DISSOLVED DISPERSED FORM. |
