This detector may be used, with suitable software, to analyze two dimensional thin-layer chromatography (TLC) plates. TRACY is a multiwire proportional detector which has been developed especially

One of the major disadvantages of such spark chambers has been the lack of any digital information. This has been solved by development of EVA, an optical reading system for the BERTA where a special diode array matrix is used in conjunction with a very fast Motorola 68000 CPU.
