NOW! A NEW CONCEPT IN GAS FLOW COUNTERS
INSTRUMENTATION IV.
for maximum efficiency with carbon 14 and other soft beta emitters featuring windowless operation for greatest sensitivity or "Micromil"* window operation for the newest and best method of counting soft beta radiation. Newest—because the exclusive "Micromil" window is so thin that it reduces the count rate for carbon-14 by less than 20%. Better—because common windowless counter problems (charge effects, chamber contamination, moisture accumulation) are completely avoided. Model D47 may be used with the automatic sample changer or chromatographic strip scanner—is the most versatile gas flow counter ever produced!
