Abstract
Method and apparatus are provided to equilibrate a solution contained in a conventional syringe. The syringe is positioned so that the tapered end of the syringe is upward relative to the flanged end of the syringe. An equilibration tube member is inserted into the tapered end of the syringe. Equilibrating gas of a known composition is delivered to an input cavity formed in a heat block. The equilibrating gas is humidified in a humidifying chamber after it exits the input cavity. The humidified, equilibrating gas then passes into an output cavity formed in the heat block. The equilibration tube member receives the gas from the output cavity and carries it downwardly into the syringe where it exits the equilibration tube member into the equilibration solution. The equilibrating gas passes upwardly through the solution to produce an equilibrated sample. Gas passing from the solution is able to exit the syringe through its tapered end.
