Analytical Services
Essential oils and aromatic chemicals are the beating heart of all olfactory experiences, and it is imperative they are verified for purity and originality. Benson Co, committed to the cause of excellence in everything sensorial, sets and strives to meet stringent quality standards of these components. We adopt physical or physio chemical techniques such as Gas Chromatography using state-of-the-art analytical instruments.
Gas Chromatography
Using the gold standard in gas chromatography (GC), the Agilent GC 8860 gas chromatograph, we ensure that the different components in a sample is measured reliably, thoroughly and cost effectively.
How it works
The strength of GC lies in its robustness and suitability to routine research and analysis, which is very helpful in business-as-usual aroma and personal care product analytics.
GC separates the chemical components of a sample mixture and then detects their properties to determine the extent of their presence or absence. The sample solution injected into the instrument enters a gas stream, which transports the sample into a separation tube known as the "column." (Helium or nitrogen is used as the ‘carrier gas’.) GC separates the different components inside the column, with the detector measuring the quantity of the components that exit the column. To measure a sample with an unknown concentration, a standard sample with known concentration is injected into the instrument. The standard sample peak retention time (appearance time) and area are compared to the test sample to calculate the concentration.
