English to Russian Science Chemistry; Chem Sci/Eng

Коллеги, специализирующиеся на химической и экотоксикологической тематике, проконсультируйте, п-та, по поводу этого термина. В моем тексте он (в различных формах) встречается в следующих предложениях:

Sensitivity of the analytical method and the *analytical recoveries* are not reported.
The accuracy of the analytical methods was examined by determining the *recovery* of known amount of the chemical in water or tissue.
The experimental procedures were adjusted so that at least 90% of the added substance was *recovered*.
It is likely that the measured concentrations underestimate the real concentrations of methoxychlor because aged sediments will sorb the substance more strongly than a spiked sample generated for *recovery* purposes in the laboratory.
It was found in 3 out of 72 (4.1%) adipose tissue samples from pregnant women at a concentration range of 106–817.85 ng/g of fat (mean value: 347.73 ng/g of fat; SD: 407.19 ng/g of fat; *recovery rate* of 97%).
….collected between March 2015 and April 2016 with *laboratory recoveries* ≥ 98.2%
The *recoveries* of all compounds ranged from 72–119% in plasma samples and LODs and LOQs were 0.08–2.31 ng/mL and 0.26–7.69 ng/mL, respectively.
Procedural mean *recovery* was 91.08%.
*Recoveries* of surrogate standards were higher than 76% for all samples.
*Recovery experiments* for both water and organisms showed recoveries over 85% for the test substances.
