Kobashi New state of the art water filtration system.
Kobashi water comes from a spring aquifer 66m below
the pristine hills of higher Cotley surrounded by the
ancient oak forest (Dandyland wood) and Dartmoor National Park.
When you purchase Kobashi Products your money is reinvested
to improve our already premium quality.
We wanted the best water for Kobashi products and drinking.
The system cost over 14,000GBP and filters to 5 microns.
Mass Spectrum HP MS 5972 quadrapole detector, GC 5890 and Auto Sampler
The main analysis on each oil is carried out using gas-chromatography / mass-spectroscopy (GC-MS).
This type of analysis gives information about the individual components of each oil, and their relative amounts. See below for more information.
The physical properties of each oil are also tested to ensure that they are within the expected range for each oil (e.g., density). GC-MS Analysis Component identification The different components of each oil are identified using the following databases;
1.) Comparison of the GC retention time with a retention time library.
a) Comparison of the mass spectrum with the Wiley275.L, Wiley7n.L, and HPCH1607.L mass spectra librarys, containing over 360 000 entries. )
Comparison with pure 'standards' for certain- components, especially unwanted contaminants such as phthalates.
2.) Cross-referencing with other oils.
3.) Comparison with published data on each essential oil
4.) Analysis run on quantified library of pesticides to PPT accuracy. ppm = parts per million
1 ppm = 1/1,000,000 = 0.000001 = 0.0001%
10 ppm = 10/1,000,000 = 0.00001 = 0.001%
100 ppm = 100/1,000,000 = 0.0001 = 0.01%
200 ppm = 200/1,000,000 = 0.0002 = 0.02%
400 ppm = 200/1,000,000 = 0.0002 = 0.04%
1000 ppm = 5000/1,000,000 = 0.005 = 0.1%
2000 ppm = 5000/1,000,000 = 0.005 = 0.2%
10,000 ppm = 10000/1,000,000 = 0.01 = 1.0%
20,000 ppm = 20000/1,000,000 = 0.02 = 2.0%
