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 1, 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 1, English, - hydrophobic%20chromatography

Certaines observations faites en chromatographie d'affinité ont montré que divers effets non spécifiques étaient attribuables à des interactions de type hydrophobe. De là est venue l'idée d'employer des chaînes carbonées fixées à un support d'agarose. On dispose maintenant de familles de composés, ne différant entre eux que par de minimes variantes de structure, mais présentant des propriétés chromatographiques intéressantes. Diverses protéines se fixent réversiblement et selon des modalités variées à ces chaînes hydrophobes : c'est donc une possibilité de séparation. Cette chromatographie "hydrophobe" est actuellement en expansion.  2, record 1, French, - chromatographie%20hydrophobe

Quotient of the luminous flux incident on an infinitesimal element of a surface containing the point under consideration, by the area of that element.  3, record 2, English, - illuminance

Record number: 2, Textual support number: 1 CONT

Illuminance (usually ’E’ in formulas) is the total amount of visible light illuminating (incident upon) a point on a surface from all directions above the surface. This "surface" can be a physical surface or an imaginary plane. Therefore illuminance is equivalent to irradiance weighted with the response curve of the human eye.  4, record 2, English, - illuminance

Record number: 2, Textual support number: 1 OBS

Standard unit for illuminance is Lux(lx) which is lumens per square meter(lm/m²). There are several older units of illuminance : footcandle : 1 fc=10. 764 lx; phot : 1 ph=10 000 lx. Typical illuminance values are : 1 lx=full moon; 10 lx=street lighting; 100-1 000 lx=workspace lighting; 10 000 lx=surgery lighting; 100 000 lx=plain sunshine.  4, record 2, English, - illuminance
