ActLabs (stream sediment) INAA (34 elements + Au + Wt) Rb, d.l. = 15ppm



Activation Laboratories Limited, stream sediment; Instrumental Neutron Activation Analysis (Au, Ag, As, Ba, Br, Ca, Co, Cr, Cs, Fe, Hf, Hg, Ir, Mo, Na, Ni, Rb, Sb, Sc,Se, Sn, Sr, Ta, Th, U, W, Zn, La, Ce, Nd, Sm, Eu, Tb, Yb, Lu, Wt) Rb, detection limit = 15 ppm

General Methodology:

Weighed and encapsulated samples are packaged for irradiation along with internal standards and international reference materials.  Samples and standards are irradiated together with neutron flux monitors in a two megawatt pool type reactor.  After a seven day decay period, samples are measured on a high resolution germanium detector.  Computer control is achieved with a Microvax II computer.  Typical counting times are 500 seconds.
