Determination of the ash content of coal without ashing: a simple technique using laser-induced breakdown spectroscopy
Haider, A F M Yusuf; Rony, M. A.; Abedin, K. M. (© 2013 American Chemical Society, 2013-07-18)The bituminous coal samples were analyzed using the technique of laser-induced breakdown spectroscopy (LIBS). The fraction of the ash content of the coal was spectroscopically determined by a technique requiring only two ... -
A quick method to determine the impurity content in gold ornaments by LIBS technique
Haider, A F M Yusuf; Sengupta, S.; Abedin, K. M. (© 2015 SciTePress, 2015)Laser induced breakdown spectroscopy (LIBS) and low energy dispersive X-ray fluorescence (ED-XRF) spectrometer, were used to determine the line intensity and concentration ratios of the major impurities (Cu and Ag) with ... -
Radiative lifetime measurement of excited neutral nitrogen atoms by time resolved laser-induced breakdown spectroscopy
Haider, A F M Yusuf; Ira, Mehera Kamal; Khan, Z. H.; Abedin, K. M. (© 2014 Royal Society of Chemistry, 2014-08)Lifetimes of the excited 2P2 (3P) 3p 4S3/2 level of a nitrogen atom corresponding to transitions to different lower states have been estimated by measuring the line intensity of a transition as a function of the delay time ...
