Berthold Multi Crystal LB 2111 RIA Counter
The LB 2111 Multi Crystal Gamma Counter is a remarkably simple system for gamma counting applications that delivers consistent and reliable results. Due to its compact size, the system can fit into virtually any laboratory setting. The instrument is PC controlled using either LBIS or the advanced MikroWin software. The LB 2111 Multi Crystal Gamma Counter is available as a 12-detector unit and to increase throughput, a second detector block can be added resulting in a 24-detector system.
The Multi Crystal Gamma Counter uses high-performance NaI well-type detectors that minimize variance effects caused by sample volume and position to guarantee best counting efficiencies. The crystals cover an energy range from 10 to 510 KeV suitable to detect 125I, 57Co, 131I, 51CR, 75Se and 99TC. The 6 mm lead shielding surrounds each detector providing 12 mm lead shielding between detectors to decrease crosstalk between samples and/or background radiation.
The 12-detector version of the Gamma Counter enables analysis of 204 samples in 17 minutes using a 1-minute counting time per sample and more than 1,300 samples an hour can be measured using the 24-detector model. A complete series of measurements can be prepared in advance using multiple sample racks and numerous tubes. As the Multi Crystal contains no moving parts, sample jamming and expensive belt repairs are never a problem.
The sample rack concept of the Gamma Counter prevents contamination entering the instrument from tubes that are contaminated on the outside. The tubes are placed into racks for signal measurement which can be cleaned and decontaminated easily. To satisfy quality management requirements LBIS as well as MikroWin support QM functions. Including efficiency, absolute & relative background, relative detector efficiency and high voltage adjustment. In order to facilitate instrument QC a single-tube or 12-tube 125I or 57Co sources of 2 KBq/tube are available.
Several software options are available for measurement and data analysis:
RIA and IRMA immunoassays mainly with 125I, including, but not limited to
Other applications with gamma-emitting isotopes
