Static, method coating

Initially, this was acliieved by the apiilication of an overall coat of grey jiaint of some shade or other, a colour that was both cheap and plentiful, and easy to apply. On the face of it such a measure of camouflage appeared to be effective enough in practice. Certainly it was as effective as any static method of protection was expected to be and it was...

The columns used were 20 m long, 300 pm ID. and were pretreated with colloidal silicic acid to stabilize the film of stationary phase. The columns were coated with 0.15% solution of the stationary phase in chloroform using the static method of coating (the different methods of coating capillary columns will be described later). Prior to use, each column was conditioned at 175°C in a stream of hydrogen. The...

Many attempts have been made to detemiine by other means different to the classical shake-flask method, which include countercurrent chromatography [3], and Reversed-Ph e Liquid Chromatography (RPLC) with C8, Cl8, 1-octanol coated Cl8 and phenyl stationary plmses [4], The establishment of a correlation between retention data in RPLC and log P assumes that die extent of chromatographic retention reflects the hydrophobicity of a solute. This approach is known as quantitative structure-retention relationships (QSRR) [5]. Chromatographic techniques offer a number of advantages over the static method. A great amount of relatively precise and reproducible data can be readily obtained, and the determinations are rapid and easy to be automated. Only a very small amount of sample is required, a wide dynamic range may exist and the impurities present in the sample can be simultaneously separated. 

Preparation of the columns is based on a two-step procedure, namely 1) preparation of a slurry where the adsorbent (graphitized carbon black) and the liquid phase (for instance, SP-1000) are mixed together in a suitable solvent and sonicated 2) coating of the capillary columns by means of a static method using the prepared slurry. 

In Nikelly s opinion dynamically coated SCOT columns are almost equivalent to those made by the static method in terms of efficiency and capacity. 

Usually, a ferroelectric thin film sample fabricated by the sol-gel method is coated on a substrate, which is much thicker than the film. The piezoelectric constant, 433, of the thin film sample can be measured by the static (or quasi-static) method and the electromechanical coupling factor 33 can be calculated from the known dielectric constant and the elastic coefficients 3. It is hard to measure a thin film/substrate system by a dynamic method, e.g., the transportation line method, because the vibrator is a thin film/substrate system and the major vibration is caused by the substrate, not by the film. 

The paper discusses the application of dynamic indentation method and apparatus for the evaluation of viscoelastic properties of polymeric materials. The three-element model of viscoelastic material has been used to calculate the rigidity and the viscosity. Using a measurements of the indentation as a function of a current velocity change on impact with the material under test, the contact force and the displacement diagrams as a function of time are plotted. Experimental results of the testing of polyvinyl chloride cable coating by dynamic indentation method and data of the static tensile test are presented. 

The object of all coating procedures is the distribution of the stationary phase as a thin, even film that coaq>letely covers the glass surface [139,140,143,146]. Dynulc coating and static coating methods, with several individual variations are used for this purpose. 

Evaporation at atmospheric pressure, called the free release static coating method, has not been as widely used or evaluated as the vacuum method [146,226,234]. The experimental , arrangement is... 

The desired IL monomers are mixed with a free-radical initiator (azobisiso-butyronitrile, AIBN) in dichloromethane and coated onto the wall of the capillary column using the static coating method. The capillary is then sealed at both ends and heated to initiate polymerization. Finally, the capillary is unsealed and placed in a gas chromatograph and subsequently conditioned to remove any excess AIBN that did not completely decompose or react.
