Product Description

Download Product Brochure

Based on the tremendous success of the Hidex 300 SL Automatic TDCR liquid scintillation counter Hidex has developed a new instrument for challenging low radioactivity applications.

The Hidex 300 SL super low-level scintillation counter is equipped with additional lead shielding, low level PMT detectors and an active guard detector for further background reduction. The instrument is ideal for 3H in water measurements as well as other low-level environmental monitoring, radiocarbon dating and biofuel verification applications.

The advanced Active Guard is a separate scintillator detector which detects and subtracts real-time background radiation. The guard can be turned off for high energy samples and does not interfere with alpha/beta separation.

Digital Pb shield is a proprietary Hidex spectral fitting algorithm that improves counting performance by utilizing spectrum information for active sample tritium counts and background counts.

New Active Guard for low level environmental measurements:

  • 3H & 14C in natural waters
  • ground water dating (3H)
  • 90Y/90Sr
  • gross alpha/beta
  • biobased 14C
  • low level alphas
  • 55Fe, 66Ni
  • 3H & 90Sr radiobioassays
