The phrase "in the case of samples" is correct and usable in written English.
It can be used when discussing specific instances or situations involving samples, often in scientific or analytical contexts.
Example: "In the case of samples collected from the field, we need to ensure proper labeling and storage."
Alternatives: "regarding samples" or "with respect to samples".
In the case of samples containing 20% PEHP the crystallites were of the β-form.
In the case of samples with a higher degree of reduction, the electron donor power is shown by tetracyanoethylene adsorption.
In the case of samples nitrided at 500 Pa, a macroscopically visible ring is obtained with low hardness inside the ring.
Surprisingly, degrees of saturation larger than one are systematically obtained in the laboratory at low suction values in the case of samples of expansive clay tested at constant volume.
Spectra were only characterized by peaks corresponding to sulfate minerals, such as gypsum (414 cm−1, 493 cm−1008008 cm−1 and 1135 cm−1) and to SiO2 (463 cm−1) in the case of samples used for silicification41 (Fig. 3b and c).
In the case of samples with UV absorber the fluorescence data showed a barrier imposed by this additive in the formation of the monohydroxy-terephthalate. Scanning electron microcopy of fracture surfaces showed that film ductility is highly reduced after exposure.
Damage sizes as determined from ultrasonic nondestructive evaluation (NDE) were comparable to room temperature samples except in the case of samples that were subjected to cold dry conditioning for 6 months.
Eventually, impedance spectroscopy analysis did not appear sensitive to intermediate adsorption, plausibly because of the low variation of the coverage within the Tafel region; a poorly resolved contribution related to porosity was found in the case of samples prepared at 350 °C.
Half time of crystallization and induction period of crystallization enabled an in-depth analysis of the crystallization process which led to the conclusion that the rates of nucleation and crystallization increased significantly particularly in the case of samples with a small content of carbon black.
No peaks corresponding to Nickel oxide were observed in the case of samples on SAC.
However, in the case of samples on WAC, the XRD pattern consists of characteristic peaks of Nickel and Nickel oxide.
