Query: Comments on the papers recently published by Kalaivani et al   We argue that the so-called l lysinium succinate (journal of crystal growth
426 (2015) 135), zinc chloride doped l lysinium succinate (journal of crystal
growth 428 (2015) 24), and l threonine phthalate (journal of crystal growth 427
(2015) 29) and sodium acetate doped l tyrosine (spectrochimica acta 136a (2015)
168) are all dubious crystals. Taking these compounds as examples we show that
that edax is an inappropriate method for characterization of new materials
based on elemental composition data.
