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
