Determination of Insulin Concentration in Camel Milk Using Ultra Violet –Visible Absorption Spectroscopy
ABSTRACT: Camel milk contains sufficient levels of insulin and does not form the coagulum in the stomach preventing degradation of insulin and act as an effective vehicle to take the milk insulin unchanged to the intestine. In present study direct spectroscopy and standard addition method, well-known methods in analytical chemistry were used for determining insulin concentration in camel milk. ...

متن کاملNear Infra-red Spectroscopy of V838 Monocerotis
Near IR, multi epoch, spectroscopic and photometric observations of the enigmatic, eruptive variable V838 Mon in the JHK bands are reported. One of unusual features of the spectra is the detection of several strong neutral TiI lines in emission in the K band. From the strength of these lines, the mass of the ejected envelope is estimated to be in the range 10−7 to 10−5 M . The spectra also show...
متن کاملQuick Detection of Contaminants Leaching from Polypropylene Centrifuge Tube with Surface Enhanced Raman Spectroscopy and Ultra Violet Absorption Spectroscopy
Anomalous surface enhanced Raman scattering (SERS) peaks are identified for liquid sample stored in polypropylene centrifuge tubes (PP tube) for months. We observed the unexpected Raman peaks during experiments for Thiamine Hydrochloride aqueous solution stored in PP tube for two months. In order to identify the contaminants we have performed SERS experiments for de-ionized water (DI water) sto...
متن کاملUltra-violet resonance Raman spectroscopy for the rapid discrimination of urinary tract infection bacteria.
The ability to identify pathogenic organisms rapidly provides significant benefits to clinicians; in particular, with respect to best prescription practices and tracking of recurrent infections. Conventional bioassays require 3-5 days before identification of an organism can be made, thus compromising the effectiveness with which patients can be treated for bacterial infections. We analysed 20 ...
