Grass Chromatography: 4 Questions

What is cannabidiol (formula, elements)?
C21H30O2
Cannabidiol is a chemical derived from the cannabis plant. It doesn’t have any psychoactive properties (so it won’t get you high). Companies are interested in it because it has analgesic (pain-relieving), anti-inflammatory, and many other properties that could potentially make it useful in medicine.

Are there any other components of marijuana that need to be considered as well? Or is cannabidiol the main component that contributes to the drug’s effects?
CBD is actually not associated with any of marijuana’s psychoactive properties. The compound that is responsible for getting you high is tetrahydrocannabinol (THC), which works by binding with the cannabinoid receptors in the brain. Though only THC is useful for recreational purposes, both compounds have similar medicinal uses.

What is it that makes CBD hazardous? What are its symptoms?
There many small studies have shown that CBD is tolerated in adults well, the most common side effects were tiredness and changes in appetite or weight.

Why did it take so long to use the GC in this field?
The marijuana industry, be it recreational or medicinal, is relatively new. Because marijuana is a Schedule I drug (according to the FDA it has a high potential for abuse and no accepted medical uses), regardless of its legality in individual states. That can make it more difficult to run tests on marijuana.

The 411 on Tattoo Ink: dangerous or not?

Title: Sensitive Determination of Volatile Organic Compounds and Aldehydes in Tattoo Inks                      The popularity of a tattoo gone from sub-culture to pop culture in recent years, however, getting a tattoo can potentially put your health at risk. A tattoo is a form of external body modification in which a needle is inserted in the dermis layer in order to transfer the pigments. Tattoo inks are a mixture of organic and metal complex dyes in various solvents; the solvents with ethyl alcohol are more commonly used as the alcohol increases the skin’s permeability but also carries more hazardous materials into the blood. Despite the high numbers of tattooed individuals, there has been no study until now of the harmful solvents and impurities contained in tattoo products.              This study used gas chromatography to develop analytical methods pertaining t...

Preserving Prehistory

A Prehistoric Egyptian Mummy: Evidence for an ‘Embalming Recipe’ and the Evolution of Early Formative Funerary Treatments When one mentions the word ‘mummy,’ Egyptian pharaohs, massive pyramids, lavish burial tombs, and an equally lavish embalming process probably come to mind. These funerary rituals were thought to have begun c. 2500 BCE. However, a recent analysis of the prehistoric Turin mummy shows that rudimentary preparations were made before then. This mummy was the perfect specimen for testing because there was no record of any preservation measures employed after the body had been discovered, which is not true for many other mummies from this period (c. 3600 BCE). Scientists took the opportunity to take textile and tissue samples and perform a battery of tests to determine many things about the life and death of the Turin mummy, but most notably, when  three textile samples from different parts of the mummy were analyzed, gas chromatography showed remnants of plant oil ...

Bad Biogas

Establishment of analysis method for methane detection by gas chromatography An analysis of methane levels in biogas determined whether the levels detected by gas chromatography in the process of food waste fermentation were safe. As methane has greenhouse effects twenty-five times stronger than those of carbon, the analysis is vital to determine the safety of basic food fermentation. First, a sample of biogas was collected from a digestion reactor. After analyzing this substance, only one peak that belonged to methane appeared in the chromatogram as the only other substance was air. According to a table created by the researchers, methane content rose slightly to 12.75% in the initial fermentation phase before shooting to 63.03% in the next phase and settling to 50.76% in the last phase. Since the working curve range unfortunately only went up to 44%, the method of collection used was not acceptable for determining methane levels in biogas.       ...
