Winefordner et al. described a special, more sensitive cell based on changes in dielectric constant and constructed to allow gas flow between the plates of a capacitor which is a part of the tank circuit of a 70-Mc/sec Clapp oscillator, the output of which is beat against that of a reference oscillator. With the difference frequency between oscillators adjusted to zero with pure carrier gas flowing through the detector, the presence of a foreign vapor in the cell will produce a different frequency which is linearly related to the amount of material introduced through an injection port in the carrier gas stream and inversely proportional to the absolute temperature for a given component at a constant density or concentration in the cell and for a particular operating frequency.  2, record 3, English, - Clapp%20oscillator

Type of chromatography developed following the observation that certain proteins were unexpectedly retained on affinity gels containing hydrophobic spacer arms. This concept was extended, and families of hydrophobic adsorbents prepared using a homologous series of hydrocarbon chains of different lengths. In practice most proteins can be satisfactorily purified using C-8 or phenyl substituents. Hydrophobic interactions are strongest at high ionic strength, so adsorption to a hydrophobic matrix can be conveniently performed after a salt precipitation or ion exchange chromatography step. Elution can be effected by altering the solvent ionic strength, pH, or composition or by the use of a dielectric constant modifier such as ethanediol.  2, record 4, English, - hydrophobic%20chromatography

When carrying out the hydrophobic chromatography of human urokinase ..., the solution containing the crude urokinase which is prepared from human urine in the usual simple method, is adjusted to a salt concentration of 0.2 to 2 M, preferably 0.2 to 1 M. The solution is then made to flow through the hydrophobic column packed with the protein adsorbent of this process.... The pH is not critical when carrying out the hydrophobic chromatography, however, the pH is usually adjusted to pH 5.5 to 10, preferably 6 to 8.5 at which pH urokinase is stable against inactivation. Purified urokinase can be obtained by treating the effluent from the hydrophobic column in a usual method, namely by lyophilization after desalting.  3, record 4, English, - hydrophobic%20chromatography
