14C-Urea Breath Test system


14C Urea Breath Test system, including instruments and testing kits, which uses the method of ionization counting to measure 14C. β-ray emitted by 14C enters into Detector`s GM tube and causes inert gas ionization. The anions of the gas ionized are speeded up to move to the anode of the GM tube under strong field. More gases are ionized by colliding with other gas molecules; consequently lots of charged ions are generated instantly. A detectable negative impulse is then generated and fed into the single- chip computer system and counted after it is amplified. The counting result is displayed on the Detector`s LCD and can be printed.
