Sentence examples for external contaminants from inspiring English sources

Strippable coatings have been used for more than 50 years for various applications for protection of surfaces from external contaminants.

Unfortunately, the mechanism by which these devices operate leads to aspiration of external contaminants back into the device at the end of the spray cycle.

For these applications, the coatings have to be non-penetrable and resistant to water and other external contaminants A wide variety of solvent- and water-based strippable coatings are available for precision cleaning of surfaces and for protecting surfaces that have been cleaned.

While, at the macrostructural level, physical exclusion of microbes and other external contaminants may be an important feature, and, at the ultrastructural level, the adsorption of DNA to hydroxyapatite and/or binding of DNA to Type I collagen may stabilise the DNA, the relative contribution of each, and what other factors may be relevant, are unclear.

Thus, preference for lower pH may be advantageous to the mutant; also lower pH would mean fewer chances of external contaminants.

The HYAFF® layer is physically coupled with a transparent and flexible film of a medical-grade synthetic elastomer that acts as a semipermeable barrier against external contaminants.

In ancient mtDNA analysis, sequences can be recovered that are not authentic but derive from some external contaminant or the nuclear genome.

The occurrence of contamination on the plate did not show any trend (figure 1C), suggesting that the accidental entry of external contaminant DNA into a well during experiments was randomly distributed.

Sequences that were likely to be derived from non-spider contaminants (mainly parasitic, commensal and external contaminant organisms - the spider "meta-transcriptome"), were identified by filtering the blastx results for all putatively non-metazoan transcripts.

However, it is also likely that the use of ncDNA resulted in the detection of a large and diverse spider "meta-transcriptome" – an inventory of expressed genes from organisms associated with the spiders (endo- and ectoparasites, commensal and external contaminant organisms).

Hence it may be difficult to distinguish between contaminants taken up and those related to external contamination.
