This new strategy was successfully applied to determine nitrogen contents of NCs in real explosive samples (smokeless gunpowders).
So "Ha Di Ka," featuring Big Chief Juan Pardo and his Mardi Gras Indian tribe, Golden Comanche, isn't just one more Indian chant backed by a band; it's got fat-bottomed electronics, a deranged psychedelic guitar and explosive samples grappling with Galactic's keyboard funk.
Three standard explosive samples (TNT, RDX, and PETN) were purchased from AccuStandard, Inc. (New Haven, CT) and used without further purification.
It is important to note that the explosive sample was 3 mm thick, so the data cannot be directly compared with those of the simulants.
In this work, we proposed a novel method for simultaneous determination of pentaerythritol tetranitrate (PETN), 1,3,5-trinitroperhydro-1,3,5-triazine (RDX), and 2,4,6-trinaitrotolunene (TNT) in binary-component polymer bonded explosive (PBX) samples by means of a combination of ultraviolet (UV) spectrophotometry with multivariable calibration methods.
The method followed by gas chromatography with micro-electron capture detector (GC-μECD), was successfully applied for determination of nitroaromatic explosives in water samples.
After deciding she can't do this to her gentle employers, she decides to complete a British spying mission instead, by stealing the formula for a secret explosive, taking a sample home to London hidden in her hat.
In this work, colloidal gel of magnetic carbon nanotube and deep eutectic solvent was prepared and used in developing a fast and efficient dispersive solid phase extraction method for enrichment of ultra-trace amounts of nitroaromatic explosives in water samples.
A method for the sensitive quantification of trace amounts of organic explosives in water samples was developed by using stir bar sorptive extraction (SBSE) followed by liquid desorption and ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC MS/MS).
A fast, simple, inexpensive, sensitive, efficient and environmental friendly direct ultrasound-assisted dispersive liquid liquid microextraction (DUSA-DLLME) procedure has been developed to concentrate five nitroaromatic explosives from water samples prior to quantification by gas chromatography mass spectrometry (GC MS).
During periods of volcanic unrest (including explosive activity), continuous sampling by hand at the lakeshore is difficult or impossible, in contrast to data collection by seismometer and GNSS.
