Palm oil, spiked with MOSH and MOAH, by using a lubricant oil and a technical creeping oil.
The concentration levels are:
Total MOSH (≥ n-C10 to ≤ n-C50)
32.6 mg/kg (assigned values from method ring test P1917-MRT)
Total MOAH (≥ n-C10 to ≤ n-C50)
4.11 mg/kg (assigned values from method ring test P1917-MRT)
The spiked levels are provided in the specification related to the reference material
If the levels of MOSH and MOAH are quantified in P1917-RMPo1 (spiked palm oil) and P1917-BLPo1 (unspiked palm oil) and the difference between the unspiked material and the spiked material is calculated, the spiked levels can be used as an approximation of the true values of MOSH and MOAH.
The reference material is validated in the method ring test P1917-MRT. Please refer to the summary of the specification for more information.
The reference material is available until June 2021 (or end of stock).
