The phrase "a sample to characterize" is correct and usable in written English.
It can be used in contexts where you are discussing the purpose of a sample, particularly in scientific or analytical settings.
Example: "We collected a sample to characterize the chemical composition of the soil."
Alternatives: "a sample for analysis" or "a sample for identification".
Thus, we selected Lig 290 as a candidate sample to characterize as a potential high-lipid producing pH tolerant microalgae strain, which could be used in biofuel production.
Lambda phage DNA was used as a model sample to characterize the chip.
Previous studies on the reproducibility of phthalate metabolite concentrations in urine samples among nonpregnant individuals have shown a wide range of estimates of within-person variability (Fromme et al. 2007; Hauser et al. 2004; Hoppin et al. 2002; Teitelbaum et al. 2007), leading to concerns regarding the approach of relying on a single sample to characterize exposure.
We found that though DAP metabolites in single or multiple spot samples are strongly correlated with levels in same-day 24-hr samples, children's urinary DAP concentrations vary greatly from day to day, and use of spot samples to characterize a child's cumulative weekly exposure results in a moderate degree of misclassification.
We used GS-FLX Titanium Sequencing (Roche/454-Sequencing) of two normalized libraries of pooled RNA samples to characterize a transcriptome of the dark-eyed junco (Junco hyemalis), a North American sparrow that is a classically studied species in the fields of photoperiodism, speciation, and hormone-mediated behavior.
Reservoir engineers rely on a limited number of small core samples to characterize many of the large-scale multiphase flow petrophysical properties affecting the production and recovery of hydrocarbon fields.
Some studies of non-participation rely on follow-up interviews or questionnaires on a sample of nonparticipants to characterize the entire group, but the proportion of initial non-respondents who complete a follow-up questionnaire may be quite low [ 32, 33].
In this work we use a consecutive sampling method to characterize the dispersion patterns of data generated from Illumina fiberoptic bead-based oligonucleotide arrays.
IVIVCs should utilize sufficient subjects (a statistically powered sample) to adequately characterize the drug product performance.
We collected forest plot data using a multi-scale sampling design to characterize pre-infestation forest composition and ongoing tree mortality along environmental and time-since-fire gradients.
