General description

25 Glass plates 5 x 10 cm
RP modified plates serve two purposes: act as a pilot method for HPLC and allow to choose various solvent system for special separations. Our RP-modified silica layers are well suited for many separation challenges that unmodified silica cannot overcome. These layers use aqueous solvent systems to separate extremely non-polar substances and analyze particular polar substances that can adapt to ion-pair chromatography. What’s more, RP-modified silica layers are less dependent on atmospheric humidity. Unlike unmodified silica, RP-phases do not exhibit catalytic activity. This makes them the plates of choice for unstable substance that tend to experience oxidative degradation.

Application

Glass TLC plates, RP-8 modified silica gel coated with flourescent indicator F254s. The RP-8 modified silica gel TLC plates come in a quantity of 25 size 5x10 cm for thin layer chromatography applications.

Non-sedating H1-antihistamines are the recommended first-line treatment for chronic spontaneous urticaria. While efficacy studies usually apply continuous daily treatment regimens, many patients take their medication on demand. In this randomized, double-blind trial we tested whether on-demand H1-antihistamine desloratadine in standard

The efficacy of amantadine in alleviating motor symptoms of Parkinson's disease may be mediated in part by stimulation of cerebral dopa decarboxylase (DDC) activity, secondary to antagonism of N-methyl-D-aspartate (NMDA) type glutamate receptors. We tested the specific hypothesis that amantadine

The extent of the distribution of H(1)- antihistamines into the skin and H(1)-antihistamine activity in the skin are clinically relevant in the treatment of allergic skin disorders. In a prospective, randomized, double-blind, parallel-group, multiple-dose study, we gave fexofenadine 180 mg
