All Better Essentials oils are GC-MS tested to ensure 100% purity. With each batch of essential oils we bring in, we receive independently analyzed GC-MS reports. We have worked with a number of different testing labs, based on our relationship with the supplier.
You can find a link to the current batch's GC-MS report for each single essential oil on the individual product pages.
Gas chromatography-mass spectrometry (GC-MS) combines the analytical chemistry technique of gas chromatography (GC) with the mass analysis capabilities of mass spectrometry (MS). A gas sample is first injected into the GC, which is equipped with a capillary column that separates the different compounds within the sample. As the different molecules elute from the column at different times, they then enter the MS, which captures, ionizes, accelerates, deflects, and detects the ionized molecules separately. These two components (GC and MS) cannot be used to accurately identify compounds when used separately, but when used in conjunction, they allow for a sensitive degree of compound identification.
The quality of our essential oils is second to none, and we guarantee you will be satisfied. If, however, you decide you want to return your product for any reason, simply return the opened or unopened product and we will refund 100% of your purchase. Read more about our return policy here.
