In this report, we present our results from various studies to qualitatively discriminate the common military explosives viz. RDX, TNT and HMX in their pure form at a distance of ~6.5 m in standoff mode using femtosecond (fs) filament induced breakdown sp... see more

We report the ‘standoff detection’ of explosives at 1 m in laboratory conditions, for the first time in India, using Laser Induced Breakdown Spectroscopy combined with multivariate analysis. The spectra of a set of five secondary explosives were recorded ... see more

A simple, yet efficient, methodology is proposed to classify three high energy materials (HEMs) with diverse composition using nanosecond laser induced breakdown spectroscopic data. We have calculated O/N, N/H, and O/H elemental peaks ratios using a ratio... see more

Analysis of impurity in powder samples has been made by using metal-assisted laser-induced plasma spectroscopy utilizing a pulsed CO2 laser. Various powders including food powder, supplement powder, baby powder, and medicine powder were employed as sample... see more

The analytical capability of laser-produced plasma for the analysis of low alloying elements in cast iron samples has been investigated. The plasma was induced by irradiation of a sample in air at atmospheric pressure using an infrared CO2 laser. Emission... see more

Research have been conducted about calculating the plasma temperature using Laser-Induced Breakdown Spectroscopy (LIBS), located in Udayana University’s Laboratorium Penelitian Terpadu FMIPA. The calculation of Plasma Temperature is done using the Boltzma... see more

 In this work, we evaluated the use of laser-induced breakdown spectroscopy (LIBS) coupled with chemometric methods as a fast and simple technique for identifying diseased tissue in prostate cancer samples. The experimental setup consisted of a neody... see more

AbstrakDalam penelitian ini dikembangkan suatu metode untuk mendeteksi kandungan boraks dalam makanan dengan menggunakan teknik Laser Induced Breakdown Spectroscopy (LIBS). Dalam teknik ini boraks (Na2B4O7) yang berupa serbuk dicampur dengan bahan makanan... see more

AbstrakMerkuri (Hg) merupakan salah satu logam berat berbahaya, yang apabila mengenai kulit dalam konsentrasi kecilpun dapat bersifat racun. Namun, sering terjadi penyalahgunaan dengan mencampurkan merkuri ke dalam kosmetik sebagai pemutih kulit secara in... see more
