The phrase "an initial separation at" is correct and usable in written English.
It can be used when discussing the beginning of a process or event that involves dividing or distinguishing something at a specific point.
Example: "The study focused on an initial separation at the molecular level to understand the reactions better."
Alternatives: "a preliminary division at" or "an early separation at".
It also suggests that repeatability across time appears to be relatively stable after an initial separation period of at least 14 days and suggests that multiple measurements offers the potential to more accurately rank animals.
Hence, two signal vectors in the phase space with an initial separation of δ Z0 will eventually diverge at a rate given by: δ Z t ≈ e λ t δ Z 0, (8).
After an initial separation of DNA adducts by TLC, individual spots were isolated and separated further on HPLC.
At present, to achieve price bidding, China has realized an initial separation of power plants and grid enterprises, which creates conditions to optimize the allocation of resources.
Our divergence age estimates indicate an initial separation into southern and northern baboon clades 2.09 (1.54–2.71) million years ago (mya).
After equilibration, the second dimension was performed on 12.5% SDS-polyacrylamide gels at a consistent power supply (with initial separation at a constant 0.2 w/gel for 1 hour followed by 17 w/gel at 25°C).
SDS-PAGE was carried out using Hoefer SE 600 vertical chambers and a Tris-glycine buffer (25 mM Tris and 192 mM glycine) containing 0.1% w/v SDS, with initial separation at a constant 10 mA/gel for 30 min followed by 20 mA/gel.
The only way I made it through the initial separation at birth and the rejection as an adult was with the deep love of my family and the many kindred spirits that have become part of my extended family of adoption.
The snapshots demonstrate all typical features of spinodal decomposition: a quick initial separation and a much slower further coarsening.
The touch-down PCR program had an initial strand separation step at 94°C for 3 min followed by 15 cycles of denaturation at 94°C for 30 s, annealing at 65°C with delta RT-1°C in each cycle for 30 s and elongation at 72°C for 40 s; after that, similar 25 cycles with annealing temperature 50°C.
