WebHow can we increase column efficiency in GC? Decreasing particle size thus is a useful method for improving column efficiency and providing better separations. changing to particles that are half as big, while keeping the column length the same, will double the performance, but increase the required pressure by a factor of four.

When we say “GC rich”, we mean approximately 60% of the bases are either cytosine (C) or guanine (G). GC-rich DNA sequences are inherently more stable than sequences with a low GC content. For PCR, this means that the higher the GC content, the higher the melting point of the DNA.
