The phrase "a solid sample of" is correct and usable in written English.
It can be used in scientific or technical contexts when referring to a tangible, physical specimen of a material or substance.
Example: "In our experiment, we analyzed a solid sample of the mineral to determine its composition."
Alternatives: "a physical specimen of" or "a tangible example of".
Besides providing information on the disease regulation networks in rice, they also represent a solid sample of examples for the evaluation of transgenic strategies.
A solid sample of the underlying material may help clarify the magnitude of this contribution and help assign sources for the ions and elements detected.
The intensity ratios (Iovertone/ Ifundamental) for a solid sample of Hb, which was submerged in distilled water and measured with the use of the same immersive objective as RBCs, are equal to 0.14, 0.48, 0.84, and 0.33.
The MgAcAc vapor was produced by heating a solid sample of MgAcAc to around 450 K in a tantalum boat located in a heat pipe connected to the central reaction chamber.
A solid sample of 4 epi (12.5 mg, 19.4 μmol) was mixed with 3 mL of water (using an ultrasonic bath) and the slightly yellow suspension was added to the slurry of the ground leaf.
The ligand P O and P N bonds of both species are comparable to those of 2. Interestingly, when a solid sample of 3 is heated under a dynamic vacuum at 100 °C for 36 h, the P NMR spectrum indicates the formation of 4 after redissolving the solid.
For the FTIR analysis of biomass, 10 mg of a solid sample was mixed with 50 mg of spectroscopic-grade KBr, ground, and pressed to produce transparent pellets using a laboratory mill and press (QM-1 and QP-1, Chromato Science, Osaka, Japan).
We have analyzed the condition needed for thermal explosion to occur in a solid sample when the temperature of the vessel walls is raised at a constant rate.
All the collected spectra were normalized by the reflectance spectra measured from a standard (solid sample of BaSO4) to correct for the wavelength dependent response of the system.
Such photoelectron energy results in a clearly sub-micrometer information depth of this method when investigating the surface of a solid sample.
Phosphate deposition on the control resin could be attributed to immersion of a solid sample that could be partially solubilized, evoking pH changes, altering local supersaturation of SBF and causing spontaneous precipitation of calcium and phosphate ions [22].
