MOSH/MOAH Standard
(9 components)
• Developed specifically for using LC coupled with GC-FID
to accurately determine hydrocarbons found in mineral oils,
which can migrate from packaging into food.
• This 9-component mix contains non-interfering internal
standards as well as both mineral oil saturated hydrocarbon
(MOSH) and mineral oil aromatic hydrocarbon (MOAH)
markers to correctly cut fractions.
• Certified reference material (CRM) manufactured and
QC-tested in Restek’s ISO-accredited labs satisfies your ISO
requirements.
• Restek is your complete supplier for world-class MOSH/
MOAH analysis: reference standards, Allure® silica LC
columns, Rxi®-5Sil MS GC columns, accessories, and more!

ASTMMethod D6042-96
(Plastic Container Testing)
American Society for Testing and Materials (ASTM Interna-
tional) Method D6042-96—Test Method for Determination of
Phenolic Antioxidants and Erucamide Slip Additives in Poly-
propylene Homopolymer Formulations Using Liquid Chroma-
tography—is a “consensus” or “referee” method used among
plastic manufacturers and the pharmaceutical companies that
purchase plastic containers. Plastic container manufacturers use
this test to ensure the quality of their product for their phar-
maceutical customers. Pharmaceutical companies also specify
this test and provide their own lists of target compounds and
concentration limits in purchase agreements.
This test calls for isopropanol extraction, LC separation, and
UV detection. Restek offers a variety of reversed-phase LC col-
umns suitable for these separations. Restek also designed a ref-
erence standard to validate this method. This mixture contains
the common antioxidants and slips listed in ASTM D6042-96,
along with BHT.

EFSA PAH4 Standard
(4 components)
• European Food Safety Authority (EFSA) PAH4 compounds
prepared in toluene solvent.
• High 1,000 µg/mL concentration—dilute as needed to
economically prepare custom mixes.
• Low volatility—longer shelf life and more accurate results.
• High miscibility—compatible with QuEChERS solvents.
• Certified reference material (CRM) meets strict ISO quality
requirements.
• Pair with Rxi®-PAH GC column for easy separation of EFSA
PAH4 compounds from common interferences in food and
environmental samples. See
page 84for more details.
