Odor chemistry of Un-Derivatized Human Blood using zNose®
Here is an infographic which explains how the odor chemistry of human blood can be derived using zNose®. The infographic begins with an introduction to the complex structure of human blood and how the main odor-producing chemicals present in blood are amino acids. In addition, it also explains the importance of human blood and how it helps the human body to run like: *It helps in regulating the body's system *Other functions are supplying oxygen and nutrients to tissues, removing waste etc *Amino acids are the building blocks for proteins in the body *Amino acid comprise the second-largest component of human muscles, cells and tissues The infographic also informs us how detectability of odors has always presented itself as a difficult task. However, blood odors can now be chromatographed directly with the help of zNose® Then, the infographic talks about the steps for odor chemistry of human blood which are as follows: *Kovats indices are to be obtained by spiking a septa-sealed vial for measuring the headspace odor chemistry *Even the retention time is obtained in a similar way *Amino acid mix is to be injected into the vial and thermostated at 37Degrees *Odor chemistry is obtained by directly sampling headspace vapors *With a heated 200Degree inlet, it enables zNose® to detect even compounds with indices more than 2600 At the end, the infographic talks about the blood odor measurement results which are as follows: *The temperature was programmed from 40Degrees to 160Degrees *The results are compared with two blood samples and a headspace vapor containing amino acid standards *Retention time is represented by the angular variable 0 *Computer processing allows recognition of relatively known odors and chemical vapor standards This is how zNose® helps in the odor chemistry of underivatized Human Blood.
