LIBS identification of pigments from Aula Leopoldina vault

SPIE Proceedings, 2009
Aula Leopoldina is the most representative, baroque hall in Wroclaw University. In 2008, LIBS measurements of paintings layers of Aula vault were done. LIBS spectra permitted identification of mineral pigments used for specific colors of painting layers. This identification could not be unambiguous in each case since simultaneous occurrence of elements

Computer-assisted Pigment Identification in Artworks

2007
False-color infrared represents a well known method for non-invasive pigment identification in artworks. This is particularly useful in the field of conservation of cultural heritage as it provides useful information about painting materials, techniques, retouches.

Identification of pigmented gram negative bacilli.

Health laboratory science, 1978
Identification of chromogenic gram-negative bacilli on the basis of pigment production as a taxonomic criterion is unreliable. Because of this, a wide range of morphological, cultural and biochemical characteristics of bacteria in this category was examined.

Pigment analysis in the identification of "Flavobacteria".

Health laboratory science, 1977
Spectral properties of the intracellular pigments of flavpbacteroa were studied by "scanning" ultrasonic preparations, methanol extracts, MF preparations, slide cultures and whole cell suspensions. No genus-specific Amax were demonstrated with methanol extracts.

Pigment identification on medieval manuscripts by Raman microscopy

Journal of Molecular Structure, 1995
Abstract The pigments — particularly the inorganic ones — used to illuminate medieval manuscripts are surveyed and the possible methods for their identification briefly summarised. Raman microscopy is now recognized to be the most effective technique for this purpose, and a range of recent applications is surveyed.

Infrared Spectra in Identification of Painting Pigments

2009
Spektroskopski podaci u svijetu nalaze široku primjenu u identifikaciji pigmenata na predmetima različitog podrijetla i sastava, primjerice na manuskriptima, umjetničkim slikama, arheološkim ostatcima keramike i slično. Time se doprinosi rješavanju problema restauriranja, konzerviranja, datiranja i autentificiranja istraživanih predmeta. Analizirana su
