A generator system for providing a carrier-free radioisotope in the form of an acid comprises a chromatography column in tandem fluid connection with an ion exchange column the chromatography column containing a charge of a radioactive parent isotope The chromatography column charged with a parent isotope is eluted with an alkali metal salt solution to generate the radioisotope in the form

Monoclonal Antibodies Radiolabeling with Rhenium

Recently new approaches have been developed for labeling bioactive molecules [27–29] such as antibodies and fragments with rhenium-188 A promising and suitable strategy for the labeling of antibodies with rhenium-188 was proposed by Dias et al [] In this study they presented an alternative direct labeling approach based on the reaction of the with the reduced anti-CD20 antibody rituximab

Tungsten alloys provide a safer alternative to lead and their higher density also enables them to hold their shape better even under extreme conditions While uranium offers comparable density its volatile nature and the special licensing requirements needed for radioactive materials make working with it

* Most popular of the three Tungsten-Rhenium thermocouples a large selection of instrumentation is available ** Tungsten-Rhenium alloy thermocouples are supplied in standard 300 mm (12) lengths which corresponds to each leg for a 600 mm (24) total length Change suffix "-12" in model number to indicate additional length required in inches

Rhenium (Re) 24 karat ring – RWMM

Rhenium ring -- 24 karat (99 99% pure) Wedding bands have traditionally been made of gold with 14 karat (or 58 5% pure) being the most common and 18 karat (or 75% pure) also available Gold is too soft to make a durable ring out of at 24 karat purity (at least 99 9% pure) There are many alternatives to gold including the traditional precious metals silver and platinum although in recent years

The alloy RR2071 used in this study is an experimental rhenium- containing single crystal alloy Table 2 gives its composition together with that of CMSX-4 and Alloy 800 [15] In RR2071 (in comparison with CMSX4) the tungsten is replaced by a similar atomic percent of the lighter element molybdenum with the aim of reducing the density of the
