4F - B - PGNAA (0.5 ppm and 2 ppm B)

Samples 1 g in size are encapsulated in a polyethylene vial and placed in a thermalized beam of neutrons produced from a nuclear reactor. Samples are measured for the doppler broadened prompt gamma ray at 478 KeV using a high purity GE detector. Samples are compared to certified reference materials used to calibrate the system. A minimum of four standards are analyzed with every work order. Duplicates are analyzed when samples are provided. The detection limit reported is a function of the counting times required for each.
