--- |\n\n## CRIMINALISTICS\n\nMARY L.WILLARD  \nMicrochemical analysis has been used in many types of criminal investigationson account of the minuteness of the samples,which are obtained from the scene.In modern criminal investigations instrumentation is not replacing microanalysis butis being used much more extensively,especially the analytical instruments such asinfra red spectroscopy,ultra violet spectroscopy,mass spectroscope,gas chromato-graph,thin layer chromatography,nuclear magnetic resonance,electron probe andneutron bombardment(reactor).  \nIn doing this kind of work,it is necessary to have police(State Troopers etc.)and detectives,who collect the evidence and who testify in court as to its source,have some knowledge of the scientific aspects of the tests.There should be closecollaboration and understanding between the scientist and the police.This doesmean that the police should have some academic training in the fundamentals suchas English,Mathematics and the Sciences beyond the high school diploma.A B.S.or B.A.degree is becoming more and more important in order to comprehend thescientific data.This necessary basic education should certainly be reflected in thepay roll.Better trained men and better paid men will lead to the more rapidsolving of crime.  \nThe results from the newer scientific instrumentation,when used to analyzecriminal evidence,must be presented in court in such a way that the attorneys andjury know what it is all about.The scientific evidence is usually well understoodby the attorneys because they make it their business to get at least a cursory ideaof the scientific facts,and also they work in close collaboration with the scientist.visit his laboratory and read his books.  \nThe explanation of the techniques and technical methods as to how the datais obtained to a jury in five or ten minutes is something else again.It is the usualproblem of trying to get a highly technical subject to the layman's level.Usually ithas to be done in a colorful“Dick Tracy”sort of way,but still retaining the basicfundamentals.Much work can be done in this direction.  \nThe Teflon stem lets you adjust the opening from fine to coarse.A VitonO-ring seals the orifice for positive high vacuum operation.And three O-ringsprovide a triple seal within the precision-formed heavy wall glass body.The100 mm long glass side arms are also of heavy wall construction.  \nSince the parts can be disassembled in a jiffy,you can seal the hardborosilicate glass unit into any glass assembly or glass apparatus you wish;then quickly reassemble the stopcock valve.Perfect for use with corrosivegases...because of the contamination-free construction.  \n\n| Catalog No.   | Size   | Type   | Adjustable  \u003Cbr>Orifice Size   | Each   |\n| --- |
