Hidex 600 SLe Super Low Level
For challenging low level applications
For challenging low level applications
The Hidex 600 SLe super low level model 425-009 includes the same features as the standard model but has lower background making is suitable for low level applications such as detection of H-3 and gross a/b activity in drinking water. Lower background is utilized by using additional Pb shielding, low background PMTs and an active guard.
Active Guard
The 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
Digital Pb shield is a proprietary Hidex spectral fitting algorithm that decreases the background and improves the uncertainty of the results by utilizing spectrum information for active sample tritium counts and background counts.
User friendly software
The Hidex 600 SLe super low level is operated using an external PC with Windows 10 or higher based MikroWin 600 SL software, featuring an easy-to-use graphical interface and extensive data reduction capabilities, including quench curve analysis and half-life correction. The software is designed for multiuser environment, enabling unlimited number of methods for different isotopes and easy data export to Excel or other programs. Users can add samples with new methods, and high priority samples while the instrument is counting. MikroWin is also 21 CFR Part 11 compliant.
Applications
Low level environmental measurements:
H-3 & C-14 in natural waters
ground water dating (H-3)
