Gas sampler HS-20 NX

headspace

The HS-20, developed as the best solution for volatile component analysis, has been improved and introduced as the NX series. The excellent basic performance and user-friendly design provide a powerful solution for scientists in both research and quality control laboratories. The HS-20 NX series uses the isolation gas flow to reduce carryover to 1/10 of conventional models. It supports a wide range of chemical species, including high-boiling point compounds and high-polar compounds, and provides reliable analytical results. The isolation gas flow prevents sample diffusion from the vent channel, which has been a problem with conventional headspace samplers. (patent pending) Carryover of highly adsorptive compounds is reduced, eliminating the need for repeating blank runs. In the residual solvents analysis of medicines, analysis with an aqueous solvent may be performed after analysis with a DMF solvent, but with the HS-20 NX, carryover of DMF is not a problem. HS-20 NX is effective for the analysis of samples with different type of solvents or large concentration differences. High analysis reproducibility is achieved by the sample vial loading from the lower part of the oven. Shimadzu's unique sample vial delivery system minimizes heat dissipation in the HS oven as the vial enters and leaves the oven, and maintains high temperature stability during repeated analyses.
