Black pepper - MOSH and MOAH (spiked)

The ground black pepper is spiked with the lubricant oil Shell Gadus as well as with a technical white oil. 

Spiked levels are:

7.1 mg/kg of total MOSH (n-C10 to n-C50)

8.3 mg/kg of total MOAH (n-C10 to n-C50)

The raw material, which was used for the preparation of the reference material contains about 3 mg/kg of total MOSH, while it is free from total MOAH (< 1 mg/kg). The unspiked raw material is available as blank material P2103-BLPe. 

The specification of the reference material includes the comparability of results (z-score criterion) as well as the trueness of results. For evaluation of the trueness of results, the levels of total MOSH in the blank material are considered for evaluation. The quantified concentration levels of total MOSH in the blank material are subtracted from the levels of total MOSH in the reference material.

Please refer to the specification for more information related to the reference material.

The reference material is available until April 2024 (or end of stock).
