INRS/McMaster INAA (low DL)
Instrumental neutron activation analysis of 29 trace elements was performed on the till fractions. These analyses were done by the Institut national de la recherche scientifique- Géoressources (INRS) on a 3-monitor reactor at McMaster University.
Distinguishing characteristic : 2 hour count, low detection limits
Depending on sample density, 3 to 7 g of the sample were capped in 7 ml plastic containers. Samples were irradiated at McMaster University's 3 monitor reactor. A batch irradiation consisted of 21 samples and a standard (GTS-1). The delay between irradiation and counting was 5 to 8 days. A single 2 hour count (7 200 s) was performed on each sample. The distance between the sample and the detector was 2 cm. The proposed "detection limit" was calculated at the 3σ level. Measurement error for concentrations greater than 10 times the detection limit is: ± detection limit + 5% of the measured value. Below this concentration, measurement error increases.
