The phrase "a determination of primary" is not complete and lacks context, making it difficult to assess its correctness in written English.
It could be used in contexts related to decision-making or classification, but it needs additional information to clarify its meaning.
Example: "The committee reached a determination of primary importance regarding the project's objectives."
Alternatives: "an assessment of primary" or "a decision on primary".
The best-observed response was taken as a basis for the determination of primary endpoint and confirmed responses were also reported.
Isobutyl chloroformate (IBCF) has been used as a derivatization reagent for GC determination of primary and secondary low-molecular-mass aliphatic amines (Lundh and Akesson 1993); dicarboxylic acids and amino acids (Sobolevsk et al. 2004); and 4- 5- methylimidazole (Fernando and Ferreira 1997).
cThe computer algorithm with the worst agreement, which used only microbiology data for the determination of infection vs. contaminant (rule B1, Table 1), and an abbreviated time period for the determination of primary vs. secondary (rule C1, Table 1).
R2CH−CR2−NH2+ HNO2→ R2CH−CR2N2NO → N2 + R2C=CR2 or R2CH−CR2OH This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.

However, a limitation of using biomarkers is that they usually do not allow for determination of primary exposure sources and different analysis of the parent compounds (Meeker et al. 2008).
The main factor limiting the use of these models is the lack or low density and accuracy of the determination of primary soil properties needed to organize them.
In this work, a headspace solid-phase microextraction and gas chromatography coupled with mass spectrometry (HS-SPME-GC/MS) method for trace determination of primary aromatic amines was developed.
