✦ Synopsis

A method for the more efficient utilization of thin-layer chromatoplates is described.

Dipping quartz microscope slides into 46 y0 hydrogen fluoride solution is used to etch plates on which very thin layers (in general above 20 ,um thick) can then he spread, and the layers are thin enough to separate very small amounts of materials in a short time, Furthermore, thin layers of sorbent prepared in hollows etched on the quartz plates are protected from mechanical damage and are stable without the need for special storage conditions.

We present an analysis of the effect of the last-come-first-served heuristic on a linear probing hash table. We study the behavior of successful searches, assuming searches for all elements of the table are equally likely. It is known that the Robin Hood heuristic achieves minimum variance over all
