The world's leading radio flow detector offers unrivaled sensitivity, resolution and versatility.

** A newer version of this instrument is available, please see the Beta-RAM 6 radio flow detector for HPLC. ** 

With over 30 years of development and used by thousands of researchers worldwide, the Beta-RAM coupled with the industry standard Laura software, leads the way for radiochromatographers. 

Sensitivity

The Beta-RAM offers superb sensitivity with the speed and efficiency of on-line counting. Special functions such as Active Counting Mode and Stop Flow offer the users unrivaled levels of sensitivity and limits of detection.

Resolution

The B-RAM uses low dead volume fittings, tubing and mixing components to ensure the best possible resolution between peaks and to retain peak shape. Specially designed flow cells are also used to keep peak integrity. The B-RAM also supports the latest LC techniques such as UPLC, Fast LC, Rapid resolution LC.

Versatility

The B-RAM range offers the versatility of either homogeneous counting by admixing with liquid scintillator via the accurate built in pump or heterogeneous counting with a range of pre-packed solid scintillator flow cells. This makes the B-RAM the versatile choice whether you are doing the most sensitive low level metabolism work or high activity preperative HPLC work.

Resolution

Resolution is a key factor in assessing the suitability of your chromatographic method. 

The Beta-RAM has been developed to complement the latest separation technologies such as UHPLC, Fast LC, Rapid Resolution LC.

Great care has been taken with choice of fittings and flow cell design to reduce dead volume and therefore maintain peak shape and integrity.

Support for UHPLC®, Rapid Resolution LC, Fast LC

New LC technologies bring new challenges for the radio chromatographer, the new Beta-RAM model meets those challenges.

Low dead volume fittings, tubing and mixing components optimized for low flow rates ensure optimum peak shape and definition.

Specially designed flow cells in volumes ranging from 5ul give superb performance under even the most demanding conditions.

The Beta-RAM range has always offered the lowest background and the model 5 improves this even further.

The Beta-RAM also features sub-second update times to ensure the greatest accuracy with the tightest peaks.

Stop Flow

Stop flow replaces the requirement for time consuming and expensive Liquid Scintillation Counting of low level samples.

By optimizing the counting time in the detector flow cell, the combination of the stop flow option and Laura software allows the radiochemical measurement to be entirely at the threshold and measurement level required by the user.

The stop flow mode allows the user to achieve superb levels of sensitivity without the labor intensive, time consuming process of fraction collecting.

Active Counting Mode

Radio flow detection has traditionally used a variety of static parameters that are applied to the entire run. We are now able to alter the detection characteristics according to a simplified heterodyne model. This allows the system to actively monitor and adjust run conditions in real time, applying the most appropriate settings dynamically.

Standard flow:

 ACM provides unrivalled limits of detection while keeping run duration the same as a conventional run. This gives on-line detection limits previously only achieved off-line; Improved resolution and peak definition.

Is the Beta-RAM compatible with UHPLC?

Yes, the Beta-RAM has fittings, mixing components and a re-designed flow cell to reduce dead volume and retain peak shape when using low flow rates.

Can the Beta-RAM support fast update times?

Yes, the Beta-RAM can update the chromatogram up to 3 times per second to provide sufficient data points per peak even with the narrowest peaks.

Does the Beta-RAM have an integrated scintillant pump?

Yes, the B-RAM model 5B and 5C have an integrated scintillant pump that through the Laura software is capable of delivering scintillation cocktail from as low as 200ul per minute.

Can I use the Beta-RAM with a solid scintillator?

Yes, all the models of the Beta-RAM  will support the use of a flow cell packed with a solid scintillator. Calcium Fluoride, Yttrium silicate and silanized Lithium glass packed cells are available.

Is a range of flow cell sizes available?

Yes, flow cells can be provided in almost any size to suit users requirements from 5ul up to 1ml.

Can the Beta-RAM be installed vertically?

Yes, the Beta-RAM can be installed either vertically or horizontally to suit the available laboratory space.
