- Digital Pb shield with proprietary Hidex spectral fitting algorithm
Hidex 300 SL Super Low Level
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 H-3 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.
Active Guard for low level environmental measurements:
H-3 & C-14 in natural waters
ground water dating (H-3)
Y-90/Sr-90
gross alpha/beta
biobased C-14
low level alphas
Fe-55, Ni-66
H-3 & Sr-90 radiobioassays

Performance Specifications
All the measurements are performed at temperature of 22°C ± 2°C and at normal humidity conditions of Hidex laboratory, Turku, Finland (relative humidity not measured). Background may vary locally depending on natural environmental radiation.
Counting efficiency
Counting efficiency typical > 70 % for H-3 and typical > 96 % for 14C with unquenched samples.
> 35 % for H-3 quenched (8 mL water sample + 12 mL AquaLight cocktail)
α’s (Po-210, U-234/238, Am-241, Rn-222, Ra-226) > 95 %
Typical background
3 CPM with 8 mL water + 12 mL AquaLight Low Level cocktail. *Background value measured using window with 25 % counting efficiency.
< 0.3 CPM for alphas (with a/b separation option)
