GA-MA & ASSOCIATES, INC. (GA-MA) is a manufacturer of specialty products for the radiochemistry laboratory. Key product lines include a wide variety of marinelli-type containers and associated hardware designed for gamma spectroscopy applications involving solid, liquid and gas samples.

GA-MA & ASSOCIATES, INC. is a USA manufacturer that has been in business since 1975 and serves customers in the USA and on six different continents either directly or through its distribution network.

GA-MA manufactures marinelli beakers for 70 mm, 76 mm, 80 mm, 90 mm, 96 mm, 102 mm and 108 mm endcap diameters of Germanium, Sodium iodide and other types of scintillation or solid state detectors utilized in radiochemistry laboratories.

Beakers for solid or liquid sample applications are available for different sample volumes ranging from 250 mls to 4 liters.

The standard gas marinelli product line utilizes hermetically sealed plastic containers, which have operating pressure/vacuum to ± 10 psig. Custom gas marinellis are also available in aluminum or stainless steel for higher pressure applications.

The use of marinelli-type containers in gamma spectroscopy applications permits the radiochemist to obtain greater geometric detection efficiencies by positioning greater amounts of sample volume as close to the detector as possible.

GA-MA also manufactures specialty small volume radiogas containers in 25cc and 100cc.

We also have available a complete line of planchets and radiochemistry discs in aluminum, stainless steel, and special order, such as Silver, Platinum, Copper, Gold and Tantalum.

GA-MA can also manufacture custom plastic containers that have unique feature or requirements.
