Radio-tagging

Laser alignment systems use a transmitter and receiver. The system has a laser diode and a position sensor on a bracket mounted on one shaft that emits a weak and safe radio-tagged beam of light. The light ray is directed toward the other bracket on the other shaft with a reflecting prism that returns the ray back toward the first bracket into the position sen.sor eye. 

Radiolabeled photoaffinity ligands, in which the radio-tag is an integral part of the photo-phore, are used to simplify the analysis of the ligand-acceptor conjugate. 92 Identification of the photo-insertion site requires that both the photophore and the radio-tag will remain bound to the fragmented acceptor. To this end, introduction of Phe(3,5-3H2,4-NH2) offers an efficient and supposedly facile solution to this problem.

Zakharov et al. have used a radio tagging technique to measure the active site density in which polymerization is killed with labeled methanol (72, 73). They found only about 1 % or less of the chromium to be active, or about one tenth of Hogan s number. But because they calcined Cr/silica at only 400-500°C, their catalyst was probably only one-tenth as active. So the two studies are not necessarily in conflict. As expected, the active site density found by tagging increases with time during a polymerization run.

Active Centre Determination. A number of recent publications involving the use of molecular weight data, tritium quenching, - and CO radio tagging " have appeared recently in the scientific literature. Since the validity of these methods has been assessed recently by the present author" no further details will be given in this Report. The as yet unsettled controversy concerning the use of "CO tagging method should be noted. ... 

In order to obtain more information about this difficult theme, we tried to get some data on the concentration of active centres, [C ], by the radio-tagging technique using our hi dily active MgH2 /...
