The raw material related to P1917-RMPo2 contains MOSH. In order to prepare the reference material, it is spiked with a white oil, which contains MOAH, while it is free from MOSH.
The resulting concentration levels are :
Total MOSH (≥ n-C10 to ≤ n-C50)
14.2 mg/kg (assigned value from method ring test P1917-MRT)
Total MOAH (≥ n-C10 to ≤ n-C50)
6.19 mg/kg (assigned value from method ring test P1917-MRT)
The spiked level of total MOAH is provided in the specification related to the reference material.
If the levels of total MOAH are quantified in P1917-RMPo2 (spiked palm oil) and P1917-BLPo2 (unspiked palm oil) and the difference between the unspiked material and the spiked material is calculated, the spiked level of total MOAH can be used as an approximation of the true value of total 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).
