HERM LB 500 High Activity Radio Monitor

The Flow Monitor for High Activities

The HERM is a dedicated radio flow monitor for detecting gamma isotopes present in high activities e.g. in nuclear medicine or PET laboratories.

The sodium iodide crystal combined with a thick lead shielding provides a sensitive, reliable and stable measurement system. The Twin-Cell-Changer offers enough flexibility in terms of changing activities and flow rates for the flow through analysis.

Choice of operation

HERM can be used as a stand-alone system pre-configured via a terminal software or in a fully PC-controlled manner via the RadioStar software.

Similarly the signals detected in the HERM can be transferred an analogue channel (0 to 1 V) or via the digital USB connection

Twin-Cell-Changer

Each of the detection cells can be configured to the needs, i.e. activities and/or flow rates present in the analysis. A mechanism enabling immediate change between the two cells gives even more freedom in customization.

Downstream Control

Threshold values can be set in order to be able to control downstream devices like separation valves and fraction collectors even in a time-delayed way.

Validation

A built-in oscillator serves as a reference source for auto-control and GLP validation of the system.
