Beckman LS 6000

The current model Scintillation Counter offers unparalleled flexibility in a single high performance system, without the need of a dedicated external computer. Advanced electronic components, such as a Motorola 68000 Series microprocessor supported by a digital signal processor, maximize technological lifetime and make the LS 6500 fast and efficient.

A 32,768 channel multichannel analyzer gives you an eight-fold improvement in effective resolution (0.06 keV per channel) over that of conventional liquid scintillation counters (0.5 keV per channel). This provides the basis for:

Functionally very similar to the LS5801 / LS3801 with additional sophistication. Selection of programs is also accomplished through the use of command cards, but the process of editing user programs is somewhat different.

Additional functionality for the 6500 include improved counting efficiency of dry scintillant (eg ReadyCaps); a reversible belt carrier system that allows for more convenient recounting of samples; counting single racks without command card (under interrupt in the Multi Task menu), single photon counting, and dual label studies. Entering user programs involves selection of isotopes to set spectrometer windows rather that actual window energies. Thus, if you wish to count tritium in channel 1 you would select 3H for isotope one (actually this is the default). If you wish to manually set the window you may do so by entering Manual in this field. Please refer the the manual for detailed instructions.

It is important to note that if are doing a dual labeling study you should choose Isotope 1 as the lower energy isotope and Isotope 2 as the higher energy isotope. The lower limit for Isotope 2 is set the same as the upper limit for Isotope 1. Don't define multiple isotopes in singlely labeled studies as it will result in lowered counts.
