Hydrocarbon Index-Kit acc. to DIN EN ISO 9377-2/H53
Recommended Products
Application
The kit allows users to extract and analyze 20 water samples (2 series of 10 water samples) in duplicate. Recovery and Blank analysis should be run in duplicate after each series.
The following solutions should be diluted as follows prior to use:
49574 - 1:10with n-heptane
51706 - 1:10with acetone (exact concentration should be a thousand times the desired application range)
The water sample is extracted with an extracting agent. Polar substances are removed by clean up on Florisil®. The purified aliquot is analyzed by capillary chromatography using a non-polar column and a flame ionization detector. The total peak area between n-decane and n-tetracontane is measured. The concentration of mineral oil is quantified against and external standard consisting of two specified mineral oils, and the hydrocarbon oil index is calculated.
