You want to research quicker and more effectively? The Theoprax-Measuring System makes this possible! So far you have been able to record - IR-Spectra - NMR-Spectra - UV-Spectra - and so on, now with the Theoprax-Automate you can record pH-Spectra and study the interaction between different molecules in dependence on the degree of dissociation of their functional groups! The new Theoprax-Method, based on conductivity measurements, allows to characterize the interaction between molecules. In complex chemistry, the pH-spectrum makes it possible to make a statement about the concentration of the complex, complexing agent and central ion. Furthermore, it shows the preference of the complexing agent/central ion for an metal ion/complexing agent in the presence of other metal ions/complexing agents. The pH-spectrum also shows the optimum pH-value for complex formation. It is no more necessary to isolate it, you can do it in the solution. In pharmaceutical chemistry and biochemistry the pH-spectrum makes it possible to show the enzyme-inhibitor-complex, enzyme-substrate-complex, the catabolism of the substrate as well as the pH-activity-curve of the enzyme. It is also possible to show the interaction between antigen and antibody. Are you interested? Call Theoprax-Research!
