Extraction Methods:
PURELY employs industry standards and best practices for each of our oils to ensure that you receive the absolute best and most effective essential oils. By using mostly first distillation or cold pressing, depending on the product, assures the highest available beneficial properties in our oils.
Test:
Random Batch:
Each test is performed, in each batch, using random selection procedures
at random selecting stages during the processing. These random batch
test provide quality assurance that must agree and confirm with the
previous performed test outlined below.
Gas Chromatography:
Gas Chromatography is a test performed on an essential oil to determine
the chemical composition of oil compounds. Once the essential oil has
been carefully distilled from plant material, a sample is taken to
undergo testing. The oil sample is heated to a specific temperature in
the heating chamber of a gas chromatograph machine. Each compound of the
oil then vaporizes as it passes through a detector, at different rates,
and measured. The results are then analyzed to ensure the quality of an
oil.
Mass Spectrometry:
Upon completion of the gas chromatography testing, an additional test
known as mass spectrometry is performed on our oil samples for
composition. During mass spectrometry, individual compounds are ionized
and are sorted by weight to reveal the presence of particular compounds
(such as pollutants or metals) which are too heavy to be detected by the
gas chromatography. This test reveals the purity of an essential oil.
Organoleptic Testing:
To further test the purity of our oils, our team of experts perform
organoleptic testing by utilizing the human senses, such as sight,
smell, taste and touch. While organoleptic testing can not replace the
analyzation by mechanical testing, we rely heavily on the expertise of
our team and trust their ability to ensure the highest standard
attainable for our oils.
