The automated synthesis of clinically relevant amounts of 16-.sup.18F-fluoro-5-dihydrotestosterone (.sup.18F-FDHT) using a commercially available radiosynthesizer. Synthesis was performed in 90 minutes with a decay-corrected radiochemical yield of 295%. The specific activity was 4.6 Ci/mol (170 GBq/mol) at end of formulation with a starting activity of 1.0 Ci (37 GBq). The formulated .sup.18F-FDHT yielded sufficient activity for multiple patient doses and passed all quality control tests required for routine clinical use.

The present invention provides a hydrogen generating apparatus and a hydrogen generating method, wherein the hydrogen generating apparatus generates hydrogen by dehydrating formic acid, and comprises: a reactor for containing water and a heterogeneous catalyst; a formic acid feeder for feeding formic acid into the reactor; and a moisture remover for removing moisture generated from the reactor.

In a stirred tank chemical reactor the mean age of the reactor contents affects a number of properties of the product, including for example the homogeneity of the product. The mean average age of the reactor contents can be determined by constructing a transparent model of the reactor and filling it with a fluid containing a fluorescent dye and having flow properties comparable to those of the reactor in use. A light is shone on the fluid as it is stirred under reaction conditions and a clear fluid flow into the model. Pictures are taken of the reactor contents and the mean fluid age of the contents of the model are determined relative to the exit age of the contents. This approach can be applied to determine for example which reactor ports to use, what agitator to use, what flow rates to use to improve reactor function.

According to some aspects, described herein is an automated droplet-based reactor that utilizes oscillatory motion of a droplet in a tubular reactor under inert atmosphere. In some cases, such a reactor may address current shortcomings of continuous multi-phase flow platforms.
