The phrase "assurance of samples" is correct and usable in written English.
It can be used in contexts where you are discussing the reliability or quality guarantee of samples, such as in research, product testing, or quality control.
Example: "The assurance of samples provided by the laboratory ensures that our results will be accurate and trustworthy."
Alternatives: "guarantee of samples" or "confidence in samples".
The designed sampling process was empirically proven to be practically applicable and provide better scientific assurance of sampling accuracy, which may reduce economic risks and their consequent costs caused by unfavorable sampling in the propose traceability system.
For the quality assurance of our samples, the genotyping call rates were 100% for rs6958967 in both the patient and control groups.
Extensive review and quality assurance of macroinvertebrate sampling protocols, laboratory subsample counts and taxonomic resolution was completed to assure data comparability.
The approach to managing single peptide hits employed in this study is attractive in that it maintains a stringent estimated false-positive rate at the peptide level, while salvaging a significant proportion of true positive protein identifications based on the assurance of cross-sample validation and de novo peptide sequencing.
Specifically, assurance of fast sample processing would be straightforward to implement and would increase the likelihood of detecting cells if they were originally present in the sample.
qRT-PCR of a housekeeping gene proved very informative and was usable for quality assurance of each sample by defining an acceptable range of Ct scores.
Sample size for the original study was calculated based on: a) a combination of PNI theory and preliminary results from the investigators previous work and, b) criteria for number of cases in regression and, c) assurance of needed sample size for structural equation modeling [ 35].
For quality assurance purposes, 10% of samples were selected at random for repeat analysis, performed by laboratory staff blinded to sample identity.
As quality assurance measures, 15% of samples were assayed in duplicate; DNA-free negative controls were included in each 96-sample plate; samples that failed more than 10% of genotyping assays were excluded from the genotyping study.
