To know how to farm, grow, harvest, and distill essential oil certainly gives an assurance that can come in no other way. To have a background in essential oil chemistry, a laboratory for testing the oils, and the ability to formulate is not likely to be duplicated. No other company in the history of essential … Continue reading Part 20: Finding Pure Essential Oils

9. Will the soil composition and location affect the plant that is grown there, thereby making a difference in the quality or chemical profile and aroma of the essential oil that is distilled? Yes, there is usually a difference that can be small or big. Not any one thing dictates what the quality will be. … Continue reading Part 19: Finding Pure Essential Oils

Following GC analysis, we run the essential oil through a mass spectrometry instrument (MS) to get an even greater separation and can find up to another 25 to 75 minor compounds. Then with the optical refractometer, we can measure the rotation of the molecules, which helps to identify if they are natural or synthetic. Like … Continue reading Part 18: Finding Pure Essential Oils

Other factors can also vary the results of an analysis. If the essential oil sample injected into the Gas Chromatography (GC) instrument is diluted, the computer may or may not give a correct analysis. Another aspect is called “ramping” the temperature to cause more separation. This means that as the essential oil flows through the … Continue reading Part 17: Finding Pure Essential Oils

8. Are all gas chromatograph instruments the same, and will the analysis be the same from all GC instruments? No! There are several different makes of GC instruments, but that is not what makes the difference. The instrumentation inside is where the accuracy is determined. In America, essential oils were not a subject of much … Continue reading Part 16: Finding Pure Essential Oils
