The BACTEC NR730 blood culture system is a commercially available system which utilizes infrared spectrophotometry to detect bacterial growth in broth media inoculated with the blood specimen. The objective of this study is to compare this system with the conventional system used in our laboratory. A total of 479 blood samples were collected from adult patients in the Klang TAR Hospital and ino...

With the use of a high-resolution grating infrared spectrophotometer, it is possible to analyze mixtures of cholesterol esters and triglycerides on the basis of the difference in their ester carbonyl absorption frequencies. In the analysis of serum lipids, the preliminary removal of phospholipids is accomplished by a simple batch adsorption on silicic acid. Infrared absorbance measurements are ...

Tetracyclines (TCs) discharged from livestock wastewater have aroused public concerns due to their pharmacological threats to ecosystems and human health. As an important medium in the wastewater, suspended organic matters (SOMs) play vital roles in antibiotics transport and degradation. However, limited information has been reported in the relevant literature. This study investigated TCs sorpt...

The spectrum of the unidentified infrared (UIR) emission bands between 5.8 and 11.6 m has been observed for the first time for the diffuse emission of the galactic disk where the interstellar radiation field (ISRF) is quite low. The UIR bands at 6.2, 7.7, 8.6, and 11.3 m have absolute intensities which are 1/10th of the values observed in planetary and reflection nebulae. However, the intensity...

From evidence obtained by nuclear magnetic resonance, mass and infrared spectrometry, and chemical techniques, these compounds were identified as cis-4-decene-1, lodioic, cis,cis-4,7-decadiene-1, IO-dioic, cis-4-octene-1,8dioic, glutaric, and adipic acids, N-isovalerylglycine, and N-(methylenecyclopropyl)acetylglycine.

The aim of this study was to evaluate the basic freezing point of buffalo milk. Bulk milk samples were collected from buffalo and cattle farms in Caserta area from 2008 to 2014. The analysis involved a total of 1886 buffalo milk samples and 1711 bovine milk samples. These were also tested for fat, protein and lactose contents by means of infrared spectrometry. The freezing point was determined ...

We report on the synthesis of ultrathin SmVO(4) nanosheets through a simple and facile ionic liquid-assisted hydrothermal approach and their application in luminescence properties. The as-prepared products were characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy/high-resolution TEM, energy dispersive X-ray microanalysis, Fourier tran...

The recent development of Fourier transform infrared (FTIR) spectroscopic imaging has enhanced our capability to examine, on a microscopic scale, the spatial distribution of vibrational spectroscopic signatures of materials spanning the physical and biomedical disciplines. Recent activity in this emerging area has concentrated on instrumentation development, theoretical analyses to provide guid...
