SHIMADZU SCIENTIFIC INSTRUMENTS: Headspace Samplers
The HS-20 series of headspace samplers reportedly provide a reliable and robust headspace solution for any application analyzing volatile components in a difficult matrix. The HS-20 series consists of two models: a loop model for the traditional static headspace methods, and a trap model, which can adds the dynamic headspace technique for applications requiring greater sensitivity.
The series reportedly achieves a new industry standard for repeatability through precise control of gas flow rates, and a mechanism that allows a sample vial to enter the oven from the bottom. This technique can minimize heat loss and thermal instability during the equilibration step. The oven can be heated to 300°C, enabling accurate analysis of higher-boiling compounds. In addition, both models have been engineered with a short, inert sample pathway to minimize carryover from one sample to the next.
