The phrase "a mixture of a solution" is not correct and may cause confusion in written English.
It is typically used incorrectly because a solution is already a homogeneous mixture of solute and solvent, so referring to it as a mixture is redundant.
Example: "The chemist prepared a mixture of a solution to demonstrate the reaction."
Alternatives: "a blend of components" or "a combination of substances".
On passaging, the cells were detached from the flask by incubation with a mixture of an enzyme solution of 0.125% trypsin(Gibco) and 0.02% ethylenediaminetetraacetic acid (EDTA, Gibco) for 2 5 min at room temperature.
With a mixture of a SiO2 sol and a solution of lithium and cobalt acetates as the precursor, nano-SiO2 modified LiCoO2 films were fabricated by the electrostatic spray deposition (ESD) technique.
XRD and XPS analyses revealed the formation of a mixture of a carbonitride fcc solid solution, in a dominant proportion, and metallic chromium.
The following two solutions were prepared (concentrations given are those in the final CFPS mixture, which consisted of an equal mixture of Solution A and B): Solution A consisted of a small molecule substrate mixture [25] and 0.1% Tween 20 (Sigma Aldrich, St Louis, MO) to prevent bead aggregation.
In brief, a mixture of a ferrocene toluene (20.00 g L−1) solution was nebulized, using ultrasound, and fed into a quartz tube located inside a tube furnace and maintained at a temperature of 900 °C.
Peters et al. (2012) used a mixture of a radiopaque contrast medium and NaOCl solution in 300 canals in 181 patients and activated the solution with an erbium laser for 60 s in teeth with one or two canals and 120 s on teeth with three or four canals.
Monolayers were formed by immersing these substrates into an ethanolic solution containing a mixture of a symmetric tri ethylene glycol -terminated disulfide (Eglycol -terminatedric disulfide with tri(EG3ylene glycol) and maneimide heasymmetricfor 12–16 h at room temperature.
A mixture of H3PO4 solution (pH 2.5, phase A) and acetonitrile (phase B) were used as the mobile phase using the following gradient program: 0 min, 80% A, 20% B; 25 min, 20% A, 80% B; 35 min, 20% A, 80% B; 36 min, 80% A, 20% B; 41 min, 80% A, 20% B. The PDA was set at 200 600 nm, and the flow rate of the mobile phase was 0.8 mL/min.
