These syringes are ideal for purge and trap applications because the plunger can be easily removed to load water samples into the syringe barrel. Internal standard or a surrogate spike can be added through the twist valve with a 10 µL syringe. The sample syringe can also be connected directly to the purge and trap valve via the integral male luer fitting. Hamilton 5 mL and 25 mL Purge and Trap syringes were designed for the analysis of drinking water samples according to EPA purge and trap concentration techniques (see EPA methods 502.1, 502.2, 503.1, 524.1, and 524.2).
