Web1. Compound Symmetry just means that all the variances are equal and all the covariances are equal. So the same variance and covariance are used for all subjects. If you think this applies to the factors in your ANOVA model, compound symmetry is a good covariance structure to use because of its simple structure. Share. WebDec 20, 2024 · Charged surface hybrid (CSH) C18 (pH range 1-11): On this packing, low-pH mobile phases (pH ~3.0) with 0.1% formic acid can reduce tailing of both weak bases and strong bases in many cases. High-pH mobile phases (~pH 10.0) can be used to neutralize a weak base and alleviate tailing. High pH cannot be used to neutralize a strong base.

WebThe CSH particle is similar to the BEH in that both are hybrid particles; however, the former maintains a slight positive charge on the particle which is not present on the BEH particle. This slight charge acts in two ways. First, the slight positive charge improves peak shape for basic analytes at low pH due to weak ionic repulsion.
