The Analyticity of Carnap Conditionals
In section 24.D of his "Replies and systematic expositions" in the Schilpp volume, Carnap argues that every theory can be split into a component "representing the factual content of the theory", and another component serving as "analytic meaning postulates [...] for the theoretical terms". In fact, he doesn't speak about every theory, but it seems that what he says is true in general.
Take everything you believe about water, and call that your water theory. Your theory presumably contains things like "water fills our lakes and rivers", "water boils at around 100 °C under normal conditions", "water consists of H2O", and so on. All that is plainly empirical. Now the factual component of your theory, according to Carnap, is its Ramsey sentence: the theory with all occurrences of "water" replaced by a variable and prefixed by an existential quantifier binding that variable. The analytic meaning postulate then is the material conditional of the Ramsey sentence as antecedent and the theory itself as consequent. Let's call that the Carnap conditional of the theory.
