The present invention relates to a method for detecting steel sample components by using a multi-pulse laser induced plasma spectral analysis device, and in particular, to a method for detecting steel sample components by using a multi-pulse laser induced plasma spectral analysis device that includes picosecond and nanosecond laser pulse widths. A laser induced light source is a laser light source that includes nanosecond and picosecond ultrashort pulses, and one pulse laser device can be used to generate two pulse lasers, namely, a nanosecond and a picosecond laser; the two pulse lasers pass through a same output and focusing light path, so as to ensure that the two pulse lasers are focused on a same position of a sample to be detected; a surface of the sample is irradiated by using a first beam of nanosecond laser pulse to generate plasmas; subsequently, the plasmas are irradiated by using a second beam of picosecond laser pulse to enhance spectral line emission.

A system and method for non-destructive, in situ, positive material identification of a pipe selects a plurality of test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/10%, a carbon percentage within +/25%, and a manganese percentage within +/20% of a known material standard.

A precious metal source verification system includes a quantity of precious metal being formed into a shape. A quantity of trace elements is imprinted into the shape with the precious metal such that the trace elements are detectible within the shape. The quantity of trace elements defines a signature for the shape. The quantity of trace elements is at least partially destroyed or altered upon melting of the shape wherein the signature is destroyed if the shape is altered. The system provides verification of provenance of the precious metal when the signature is maintained.
