The HERM is a dedicated radio HPLC monitor which can be connected to different detectors. Providing flexibility, reproducibility and sensitivity, the HERM offers a safe and user-friendly solution for quality control laboratories. The HERM with NaI detector for gamma and high energy beta isotopes combines an extremely sensitive NaI detector with a compact shielding, and can detect even low energy gamma isotopes like 125I with high efficiency. For PET and direct luminescence, the HERM with fLumo detector is available.
The HERM makes integration into any existing HPLC system very easy. The PC connection can be established instantly via the USB port or by using the analog 0-1 V output. Its compact design makes it easy to fit in to a hot cell.
The NaI detector option combines an extremely sensitive detector with a compact shielding. Even low energy gamma isotopes like 125I can be detected with high efficiency. Lead shielding ensures low backgrounds even when there is high external radiation.
The HERM LB 500 has been designed to be intuitive and easy to use to get you up and running quickly. Standard tubing is used to create the flow cell volume. This provides maximum user flexibility. In addition, changing cells has been simplified as much as possible. The twin cell changer enables the user to easily switch between two different cell volumes. If required by GLP regulations, the cell volume can be fixed to just one volume using the optional single volume insert. The system has been designed to avoid accidental parameter modifications eliminating manual adjustment knobs: all instrument parameters are controlled remotely.
Dual operation mode
The HERM system can be installed in multiple distinct configurations, providing more flexibility and convenience. The comfortable stand-alone configuration provides an analog signal which can be easily integrated into an existing HPLC system. The system is equipped with a flash memory and a powerful CPU. Alternatively, the system can be installed in the PC-controlled configuration via a USB connection for digital data acquisition.
The HERM Controller is the software interface to the instrument; it controls all functions and collects the data. The RadioStar software combines the ability to run sophisticated measurements with a user-friendly operation and user interface. In addition, a Chromeleon™ driver is available. Chromeleon™ is known as a very versatile chromatography software package supporting many different hardware solutions. The driver is fully certified and digitally signed by Thermo Scientific™ and runs with versions 6.x and 7.x.
