Simple Fractionating Device for Chromatographic Analysis

Cereal Components, A Review of Carbohydrates of Wheat and Other Cereal Grains

“…Additional support for this general type of structure for many glucofructosans has been accumulating as a result of studies similar to that described above (5, 6, 9, 27, 32) and also from enzymic investigations (77, 18, 22, 26, 43, 51). It has been suggested therefore, that the glucofructosans are enzymically synthesized by transfructosidation from a sucrose primer (9,13,16).…”

Chromatographic Separation of Sugars with Hydrocellulose

“…Although cellulose and certain hydrocelluloses have been used successfully for separating various mixtures of sugars and their methyl derivatives (2,8), there is need of an adsorbent with a better resolving power and a greater capacity. On the assumption that there is considerable association of cellulose molecules through hydrogen bonding (10), a considerable portion of the surface of the cellulose plays little or no part in chromatographic separations and hence the capacity of unmodified cellulose is low.…”

Nonlinear absorption of randomly pulsating CO2laser radiation in narrow-gap semiconductors

“…A simpler and more reliable collector is now described in which rotation is continuous and the eluate is divided into fractions according to fixed intervals of time. The principle of continuous rotation has been used previously (Boggs et al 1952, Dimler et al 1953) but the collector described here does not require the use of specially modified receivers or special receiver inserts.…”
