A spectroscopic method for human sperm evaluation and characterization using Fourier Transform Infra Red (FTIR) is presented. The high sensitivity of FTIR to changes in chemical structure and arrangement of molecules and proteins makes it a powerful diagnostic tool. Our experimental results show that a simple MIR (400 cm−1 4000 cm−1) transmission spectrum of a human sperm is very fast and can b...

Fourier transform infrared (FTIR) spectroscopy has long been a powerful tool for structural analysis of membrane proteins. However, because of difficulties in resolving contributions from individual residues, most of the derived measurements tend to yield average properties for the system under study. Isotope editing, through its ability to resolve individual vibrations, establishes FTIR as a m...

The design of Agilent Cary 600 FTIR Series spectrometers focuses on performance. This is achieved through innovative optics design, with an emphasis on optical throughput. The result is an FTIR series that offers unrivalled sensitivity and performance. A larger footprint is required, but this is a negligible compromise for the customer, given the vast increase in productivity and profitability ...

A quantitative method for determining the level of plasticizer in plastics is now available for Agilent portable and handheld FTIR analyzers. The calibrated method affords a limit of quantitation as low as 0.1% as well as provides a very rapid means of screening plastic products and components. This ensures that greater volume of plastic materials can be screened more effi ciently for complianc...

For this reason, there is signifi cant interest in rapid, easy to use analytical methods that can detect if milk is adulterated and then measure the levels of the adulterants in milk. In a recent publication [1], researchers measured adulterants in milk in the laboratory using the Agilent Cary 630 FTIR spectrometer and showed that the mid FTIR system is superior to NIR spectroscopy for these de...

The aim of this study was to characterize the solid state properties of (4E)-2-(1H-pyrazol-3-ylamino)-4-(1H-pyrazol-3-ylimino)naphthalen-1(4H)-one (BiPNQ), a compound with a significant inhibitory activity against Trypanosoma cruzi, the etiological agent of Chagas disease (American trypanosomiasis). Methods used included Differential Scanning Calorimetry (DSC), Thermogravimetry (TG), Fourier Tr...

Qualitative and quantitative determination of chemicals especially that deal with drugs and pharmaceuticals can be considered as important issues in scientific research to insure human safety and security. With this direction of scientific research, folic acid had been determined qualitatively and quantitatively through applying FTIR technique. By applying a weight range of the pure compound, t...
