The phrase "sample degradation" is correct and can be used in written English.
It typically refers to the gradual decline in the quality of an original sample. For example, "The sample degradation was so severe that the test results were inaccurate."
The device quantifies sample degradation by monitoring its deformation induced by a static gravity load.
Step-wise loop tests were performed to examine the sample degradation characteristics of sand foam mixtures.
The electron gun lens was set to 0.9 kV, and objective aperture size of 30 µm was used to improve spatial resolution and limit the current to below 500 pA to reduce electron beam heating and sample degradation.
As a consequence of the higher analytical through-put less standardization is required in the analysis of labile compounds because less sample degradation is apparent.
The possibility of sample degradation was considered but discounted after an experimental examination of rotavirus stability and EM visualization of rotavirus-like particles in several untypeable samples.
Possible sample degradation was first investigated, but no significant degradation or dehydration was detected using FTIR and DSC under the experimental condition.
To avoid sample degradation and to increase extraction efficiency, quercetin hydrolysis was optimized using a central composite design to investigate the effects of acid concentration and hydrolysis time on extraction recovery.
Characterization of measurement errors, caused mainly by thermal transients and by translating the instrument sensor, demonstrated that HDD can quantify sample degradation with <6 μm precision and <10 μm temperature-induced errors.
"Needless to say, FIFA will have a task to ensure (1) that the chain of custody is maintained at all times to protect the integrity of the samples; and (2) that storage conditions are optimal throughout the transfer of the samples so to avoid any risk of sample degradation.
The laser power at the sample was approximately 3 mW to ensure no sample degradation.
This could be due to the breakdown of molecular bonds and sample degradation.
