The phrase "amount of specimen" is correct and usable in written English.
It can be used in contexts related to scientific research, laboratory work, or any situation where the quantity of a sample is being discussed.
Example: "The amount of specimen collected during the experiment was sufficient for accurate analysis."
Alternatives: "quantity of specimen" or "volume of specimen".
A small amount of specimen drift or microscope defocus could easily make this signal less visible.
The amount of specimen required in conventional XRD has limited its application, but where synchrotron XRD is available, much smaller specimens can be successfully examined [15].
FTIR is especially well-suited for such a goal, as this spectroscopy technique requires only a low amount of specimen to analyze, and carbonate ions exhibit a clear vibrational signature.
The thermal change of indium 2-ethylhexanoate monohydroxide, In(OH)(O2CCH(CH2CH3)(CH2)3CH3)2, to form indium oxide, In2O3, thin film was investigated by TG DTA MS in a He 20%O2 atmosphere with a minute amount of specimen (∼0.1 mg) in order to clarify the formation process of the indium-tin-oxide transparent conducting films (thickness, ∼240 nm).
Hair samples from 4 children and 3 caregivers were excluded because of insufficient amount of specimen.
The amount of specimen removed did not interfere with the histological assessment of the remaining prostate.
Compared with traditional methods, this microfluidic system demonstrates the advantages of faster detection, requirement of fewer amount of specimens and reagents, much compact design and lower cost as well as lower risks for human errors.
The used model was combined out of two existing models [ 24, 25] in order to maximize the amount of specimens in each goat.
In practice, especially when case investigation occurs after resolution of illness or death, as in this project, the preferred type and amount of specimens are not always available.
From each diagnosis, an almost comparable amount of specimens was used from either surgical or biopsy origin, in order to compare possible expression differences (260 surgical specimens and 201 biopsy specimens).
Of these 70 isolates, we could not perform the molecular study in 8 isolates due to an insufficient amount of specimens and we could not match the sequence of 11 isolates with our sequence database.
